What Affects the Structural Integrity of a Shipping Container?

Friday, October 15th, 2021

Purchasing new containers or used containers is a great idea for so many reasons, whether you use them for mobile offices and classrooms, or to use as storage in your backyard. Steel shipping containers are very durable and are designed to last for years, decades even – if they’re cared for properly.

Many people choose to make modifications to their shipping containers. However, they may not realize that those modifications can compromise the structural integrity of the container, resulting in long-term repercussions. In order to safely store items and valuables inside the container, the structural integrity must remain intact, for one thing, and for another, it must be able to accommodate safe alterations that you may make in the future.

Annual routine maintenance, particular to the roof and doors, will help to extend the life of your container. But there are many things you have to take into consideration that can negatively impact the structural integrity of the shipping container.

What Affects Structural Integrity? 3 Factors to Consider

There are three main factors that affect a shipping container’s structural integrity. They are:

Improper Stacking of Containers: Whether you’re stacking containers for storage purposes or you’re looking to build multiple container complexes, stacking is a common practice. When done right, it isn’t harmful to the containers. But when the containers are incorrectly piled on top of one another, they can result in structural damage as well as a dangerous situation for people around them. As such, you should always stack units at the corners (not diagonally), tying them with twist locks to ensure a multi-level shipping container building that is structurally sound.

Too Many Modifications: Alterations are a common undertaking among shipping container owners. Perhaps you would like to transform the unit into a garage space or workshop or maybe you want to add security upgrades to your mobile office so it’s safer at night when you’re not there. Whatever the case, changes to the original container are sometimes necessary and should be allowed to happen. However, you have to follow certain guidelines and precautions to ensure it remains structurally sound even after the modifications. For instance, you can’t cut out too large a space to accommodate more doors or cut too close to the corners, as this will lead to an uneven distribution of weight and a precarious situation. Keep in mind that every shipping container is carried via the corner castings, which are basically the four corners of the container. Let’s say you cut out a corner casting to make a desired modification design change. If you did this without consulting with a structural engineer, you could be sacrificing the container’s structural integrity. Drastic cuts to a wall, for example, are another way to compromise structure. If you were to cut out an entire wall, this would cause the roof to sag, while the floor would become almost spring-like. The walls carry a lot of weight in addition to the corner castings, and they are necessary to maintain the container’s  shape.

Frequent Sea Travel: The deterioration process is hastened with frequent travel and exposure to the ocean air and water. All that salt can cause corrosion, and objects in the water can result in dents. If buying a used container that has been in the ocean, make sure you fully inspect the unit, checking for signs of rust, wear and tear, and other damage. Keep in mind, if you buy a used container, this means it likely traveled at sea many times. You may want to take a look at “one-trip” containers, which have only traveled once across the sea. A used container that has been exposed to the ocean is more affordable and may be perfectly suited to your needs of storage. But if you need a structurally sound container to enhance into a classy mobile office, art space or yoga studio, you’ll want to go with one trip or new containers, especially when people’s safety is at stake.

Most Common Shipping Container Conversions in America

Thursday, September 30th, 2021


Shipping containers aren’t just used for shipping cargo. In recent years, they have become more and more popular for unique and inventive uses, from pop up coffee shops to mobile offices. Because they are made of heavy-duty steel, they’re durable, long-lasting and weatherproof, giving you many years of dependable service.

You can buy new containers or used containers, but whichever one you choose, you are free to get creative when it comes to its uses. Here are the top 10 most popular shipping container conversions in America for 2021.

1.  Residential & Business Storage

Storage is one of the main reasons why so many people choose to put shipping containers in their back yards or on their business property. There are many things you store in a shipping container, such as:

  • Furniture
  • Sports equipment
  • Documents
  • Machinery
  • Equipment
  • Stoves
  • Tables
  • Artwork
  • Newspapers
  • Books
  • Dryers
  • Washers
  • Electronics
  • Home décor
  • Lamps
  • Mattresses
  • Musical instruments
  • Ovens

So, if you have extra items that you don’t have room to store in your main office or home, use a shipping container for safe, secure and weatherproof storage. If you buy new and plan to use the container for many years, this will save you those expensive monthly storage unit costs.

2.  Restaurants & Bars

Just like the food truck trend that’s taking over work sites and college campuses all over the country, shipping container restaurants are also becoming popular in cities with high rent prices and limited space. Such containers are a great option for people who are very eco-conscious with a focus on sustainability.

3.  Pop-up Retail Shops

From boutiques and book stores to coffee shops and sunglass bodegas, pop-up container markets are also gaining in popularity. They’re especially cost effective and convenient for seasonal businesses who are only setting up shop for a month or two, such as to sell Christmas ornaments in December, fireworks in July, and Halloween costumes in October.

4.  Office Buildings

There’s a new generation infiltrating the workforce and they don’t want to be confined to boring, isolating, cookie-cutter cubicles. Instead, they’re looking for ways to modernize corporate America. That could be through the use of a single office in their backyard or an entire complex of shipping containers stacked on top of each other. These solutions give employees and business owners more flexibility, privacy and noise insulation.

5.  Emergency Hospital or Clinic

If the COVID-19 pandemic has taught us anything, it’s to be prepared. That couldn’t be more true than with hospitals, testing sites and clinics. These establishments have to be erected quickly and must be located away from the main facility for health reasons. These mobile clinics also provide patients a quick and easy way to drive through, get tested or treated, and then leave.

With the possibility of needing more beds than any one hospital can accommodate, pop-up urgent care sites are becoming crucial in America. Such emergency hospitals feature beds, medical equipment, medication, sanitizing items, and more.

6.  Swimming Pool

With vacations cut short in the last year due to the pandemic, more and more people are deciding to vacation at home instead. With that boom has come an influx of requests for shipping container pools. You can easily and cheaply convert a shipping container or two into an in-ground pool for a fraction of the cost of a real pool, which can cost upwards of $30,000.

7.  Indoor Gardens & Greenhouses

Did you know you can fit an acre’s worth of fruits, veggies, flowers and herbs into a 40-foot shipping container? It’s true. Why invest in a cumbersome and permanent greenhouse in your backyard or for your business when you can just use a shipping container and equip it with all the necessary hydroponic components? It’s time to start enjoying fresh produce no matter what the season!

8.  Toilets

There never seem to be enough portable toilets whenever you attend an outdoor event such as a wedding, fair, festival, concert or football game. Owners of these events and establishments are challenged with affordable, sanitary and mobile bathrooms to accommodate a growing number of patrons and guests.

9.  Disaster Shelters

The aftermath of a hurricane, tornado or other type of emergency situation can be a chaotic one. There are often not enough first aid centers, water distribution areas and shelters where people can get the help and relief they need. Shipping containers as emergency disaster shelters can quickly be deployed to accommodate displaced families who need safe and clean shelter. Storage containers fit the bill due to their durability, weatherproof nature, comfort and ready availability.

10.                Workshops & Studios

The pandemic has forced more and more employees to work remotely from their home. Many people were not equipped to handle a home office, usually due to lack of space or lack of privacy. But with a shipping container in your backyard, you can get both! In addition to home offices, shipping containers can be used as yoga studios, pottery studios, recording booths for bands, and more.

What to Know About Open Top Shipping Containers

Wednesday, September 15th, 2021

image above open top container

Open top shipping containers are considered specialty units, but they serve a similar storage and transport purpose as standard shipping containers. The difference is that they are able to accommodate much larger items, usually those too large to be loaded into a standard sized shipping container.

Made from corrugated steel, the top of the container is open and is covered with a soft roof or tarp, secured with removable bows. You can swing the roof away in order to add contents to the shipping container. End doors offer additional flexibility for easier loading. Dimensions and sizes vary, but because they’re not restricted by a solid roof, they have a larger capacity.

What Are the Uses for Open Top Containers?

These containers are best when you need to load scrap metal and timber with the use of large cranes. The items can simply be dropped carefully down into the top of the container, then covered with the tarp. It makes it a lot easier to load and unload cargo this way. When fully loaded, the container may likely be over height, precipitating the need for a special storage area.

You can order an oversized tarp to further secure the height of the load, which are made to order and will increase the cost to you. Your shipping provider will need to know the dimension of your over height cargo so they can provide a suitable tarp for adequate coverage.

Lashing rings secure the load inside, keeping it safe and stable. Most open top containers are 40 feet long, but they also come in 20 foot sizes.

Open top containers can also be used to remove bulk recycling products or waste items. Once weighed, they are loaded into containers and placed on cargo ships for their journey.

Common items to store in an open top container include:

  • Raw mining materials
  • Pipes
  • Tools
  • Cable spools and cables
  • Construction supplies/debris
  • Machinery attachments
  • Tall, awkward or bulky cargo
  • Logs, scrap metal, machinery and oddly-shaped items

You may opt for an open top shipping container if you have items that are larger than what you could reasonably fit inside a standard container.

In addition to being ideal for storage of bulky or awkward goods, open top containers are also convenient when the primary material handling equipment you have access to on site involves cranes. Just like standard containers, open top containers come in both 20 foot and 40 foot configurations, depending on how much stuff you need to accommodate. There are also some high cube open top shipping containers on the market, but they are rare.

If you need a container with easier loading options, particularly with more space at the top, open top storage containers are a great idea.

Modified open top shipping containers do exist, and these are containers with open tops that have been made through the modification of a standard cargo container. It’s a lot more involved than simply cutting the roof off a traditional container, though. The container will then need additional structural support to make up for the fact that there’s no roof.

Modified open tops have a lower overall capacity, more restrictions on loading and handling, and next to no resale value. On the bright side, they are a bit more affordable than original factory built open top containers, and are more readily available in specific locations and at specific times. Plus, they’re easier to find special sizes, like 40ft high cube open tops for instance.

Common Features

Common features of the open top container include:

  • Convenient design perfect for handling heavy or awkward cargo
  • Option to load through the top thanks to the use of overhead lifting equipment, or via the door if the need arises
  • PVC tarpaulins have a removable rear header to protect cargo
  • Bow devices and attachable ceiling
  • Choice of hardwood or plywood floors
  • Securing points in the bottom side rail and on floor

When it comes to floor depth, either on a 20-foot or 40-foot shipping container, these measurements can vary slightly, especially between various ages and makes. Usually, though, the floor is a bit higher than that in a standard dry shipping container that has a solid roof. That’s because the floor needs to be extra strong to make up for lack of a traditional roofing system.

6 Things to Know Before Buying a Storage Container

Tuesday, August 31st, 2021

If you are planning to buy a shipping container or storage container, there are some things to keep in mind throughout the purchase process.

1.    Duration

Ask yourself how long you need the storage container for. You may need it for several weeks, months or years. If you need it for less than a year, renting may be a better option for you. But if you need it for the long term, buying outright is the best route, which saves you money.

2.    Size

Next, what size will you need? There are several options available to you:

Two standard lengths for storage containers exist: 20-footers and 40-footers. While height and width vary, most are 8 feet wide x 8 feet 6 inches high. No matter what, make sure it has been approved by the International Standards Organization (ISO), which ensures safety, quality and consistency. With standard size of storage containers, they can all fit together or be stacked, usually up to seven units high.

You also have the option of buying non-standard, customized sizes, which you’ll pay more for because they must be welded together or cut down to size. In general, a custom container costs between 20 and 30 percent more than a standard container.

Non-standard sizes typically include:

  • 45’ length x 8’ width x 8’6” height
  • 30’ length x 8’ width x 8’6” height
  • 15’ length x 8’ width x 8’6” height

On top of those, you can choose an extra wide container, which is 10 feet across. Many in the construction and retail industry choose this option so they can store bulky items and equipment, such as seasonal inventory or heavy machinery.

3.    Features

Think about the features you want and what you need for your business. Common features and add-ons include:

  • Single/double door entry
  • Windows
  • Flooring
  • Office/storage space combo
  • Internal locking system
  • HVAC
  • Shelving

4.    Security

You will understandably want to keep the contents of your storage container safe from theft or damage. Your two main options include exterior bolt locks and interior locking mechanisms. Do your research on both, making sure they are of the highest quality. Many exterior locks on the market today can be easily cut with a bolt cutter by determined thieves. You may just need an exterior bolt lock on your container if it is placed in a heavily-monitored and secure area.

If you are concerned about security or your container is located in a sketchy area with no monitoring, you may want to install an interior locking mechanism. They cost more but they will keep your stuff safe and give you added peace of mind.

5.    Permission

In some cases, you have to get a temporary permit from your town or city to place a shipping container on your property, especially in highly trafficked areas or residential locations. While most construction and retail sites must pull a temporary permit due to the visibility, a secluded agricultural property or anywhere else that doesn’t get much traffic may not need to. Always contact the city to learn about requirements before purchasing a container.

6.    Site Preparation

You may not need much in the way of site prep if the area is level and dry. If you own a construction site and only need a temporary unit, you will likely be able to find the flattest spot for your container no problem. However, if you need a long term solution, can’t find level ground, or want the unit to stack on top of others, you will need more extensive site prep.

Check with your storage container supplier on how much clearance is needed around the site, how to prepare the ground for delivery, and what to expect on delivery day. Many will come out and take a look at the property beforehand to go over site prep suggestions with you. Just remember that rocky land, sloping landscapes and easily flooded areas are not the best places to store containers.

Now that you know what to consider before buying a storage container, you will be better able to make an informed decision.

Decorating the Interior of Your Shipping Container

Monday, August 16th, 2021

If you have purchased your shipping container for business, a home office, pop up coffee shop or some other purpose, you may now want to start the process of decorating it. Modifications are meant to enhance the usefulness and functionality of your container. You can incorporate modifications into storage containers, job site offices, sports equipment storage, labs, commercial container storage and industrial applications.

Some common modifications are:

  • Windows: These not only enhance visibility to the outside world, but they can be opened to increase ventilation within the unit. And because you will have a good view of your work site, you can effectively supervise your staff. You can add metal grates onto your windows to protect them from debris that could cause damage, such as at a construction site.
  • Insulation: This will help to control temperature changes inside your container, increasing comfort on a job site while combating dramatic changes in temperature in the case of storing heat- and cold-sensitive items.
  • Ventilation: This allows air to circulate throughout the container while controlling the humidity and condensation inside. You can even choose custom sized vents and motorized vents.
  • Electrical work: This will help to power your container so you can then add lighting, heating and cooling as well as electrical outlets for electronics, tools and appliances.
  • Partition walls: Use these to create custom storage spaces within the container, especially useful in industrial and commercial storage applications. You can use partition walls and custom roll-up doors or garage doors to split larger containers into two or more customized spaces. Use one for function and the other for storage, for example.
  • Floor: Invest in high-quality flooring for mobile offices, for example, or add anti-slip protection for temporary labs and classrooms.
  • Custom shelving: Make use of vertical space by incorporating metal or wood shelving and cubbies to keep everything organized. From storage racks to shelves, the options are endless.

Decorating: Less is More

Whether you’re using a shipping container as a tiny home or a mobile burger joint, you’ll want to make modifications that are more decorative in nature and that boost the aesthetic appeal of the interior. Shipping container interiors tend to be quite utilitarian-looking if you fail to decorate.

It’s wise to use interior design techniques to best utilize the existing space you have so it seems bigger than it really is.

One way you can do this is to consider sliding doors or barn doors in lieu of standard swinging doors, which can waste lots of space. Sliding doors operate in a straight line between open and close positions. The swept area is zero, making these a far better choice for compact container homes.

Barn doors are a type of sliding door, and run along a track mounted on the exterior of the opening. Pocket doors are another type of sliding door, but they actually disappear into the wall, thereby saving even more space when they slide.

Furniture is another way you can save space while still ensuring a pretty and comfortable interior space. Choosing furniture that pulls double or triple duty as something else is always a wise idea. For instance, an ottoman with a cover that turns over to reveal a hard surface for resting coffee cups, or a futon that folds up when not in use and acts as a daybed.

Mirrors are another component you’ll want to incorporate in your small space because they may everything look bigger. The magic lies in how they create the illusion that your room extends past the plane of its reflective surface. Yes, windows would genuinely open up the space, but they can be costly in terms of lost energy and privacy. Mirrors, on the other hand, are cheaper, simpler, and not as permanent.

Custom built-in furniture is another option to reduce cleaning and to save space. Shelves, dressers, and wardrobes can be made as built-ins to fit exactly in the designated space. For instance, custom L or U-shaped couches will expand seating options and even give you hidden storage underneath!

As you can see, there are many things you can do to enhance and decorate your shipping container. Call us for more ideas.

Before you can decorate your shipping container, you have to buy one first! We can help connect you with the right unit for your needs and point you in the right direction when it comes to modifications and accessories. Just contact us at 910-483-7828 today.


Preparing For Shipping Container Delivery

Saturday, July 31st, 2021

Once you’ve bought your shipping container, now you have to move onto the next step: preparing the site for delivery. The trucks will bring the unit to you, of course, but there are some things you can do on your end that will make the delivery go smoothly.

Preparing for delivery at your site will guarantee the safety of the driver and lead to a seamless delivery process overall. If you don’t prepare well beforehand, you could be subject to fees from your shipping container provider.

Depending upon the equipment you have ordered as well as the specific site conditions, most shipping containers will be delivered with either a roll-back truck or a flat-bed truck. That’s how we do things here at Transocean.

Roll Back Truck

Most deliveries are made with a self-unloading tractor trailer that will drop off your storage shipping container on the ground right where you want it on your site. Combined, the truck and trailer measure 55 feet long. Armed with that information, you should make sure your site is accessible for the truck to maneuver without problems.

Deliveries of 40-foot shipping containers require more clearance than 20-foot storage shipping containers because they are dropped off by a larger truck.

It’s best that the ground be dry and relatively compact at the time of delivery so the truck can get in and out without becoming stuck in the sand, mud or soft ground. You can go a step further and add 4”x 4” boards, railroad ties or concrete blocks under your container to encourage air flow so it doesn’t sink into the ground.

Here at Transocean, our standard full-length truck is able to deliver one 40-foot, 45-foot or 53-foot storage shipping container or two 20-foot storage shipping containers at one time. If you simply don’t have the room on your site, we can bring a smaller 28-foot truck to deliver one 20-foot storage shipping container, but please let us know beforehand.


The cheapest method of container delivery is via flat-bed truck because you are responsible for unloading the container yourself. Keep in mind, a 20′ container weighs about 5,000 pounds, and 40′ containers weigh about 9,000 pounds. Prior to ordering a flat-bed delivery, make sure you have access to the proper equipment to offload the unit, such as cranes, fork-lifts, top-lifts or boom-trucks. These are usually best for large orders, government agencies, or industrial customers.

Considerations for Delivery

There are a few factors to keep in mind when prepping your site for delivery.

Space Requirements

Because the drop-off trucks are very large and must be able to make wide turns, you have to ensure adequate space for them to maneuver on your property, be able to cross culverts, or smoothly navigate between gates.

If your container is being delivered on a full-sized truck with trailer, you’ll need to give the drivers at least 70 feet of open space. If delivered on a small tilt bed truck, 40 feet of open space is necessary.


While a trailer with container hits 13’6”H, it can reach as high as 16 feet when raised for offloading. Think about any overhead obstructions that could be present, such as bridges, tree branches, and wires. You don’t want to see any unfortunate accidents happen due to negligence.

Ground Type

Heavy container delivery trucks will sink in soft surface conditions such as mud and wet grass. This is why it’s imperative to select a location that features firm and level ground – not only so the trucks won’t sink but also so your container won’t sink.


Here at Transocean, our drivers are trained to deliver containers in the more precise and safe manner. Ensuring a successful delivery without damage to your surrounding property is our #1 concern. That being said, if our drivers don’t feel as though they can safely deliver your container at the given site, they will leave, but you will still be charged for the attempted delivery.

Do a sweep of the surrounding area to make sure it is open and safe. Both parties will benefit from this attention to detail in the end!

Contact Transocean Equipment Management

If you would like more detailed information on how to prepare for your specific shipping container delivery, contact us at 910-483-7828. We would be happy to inform you of the specific requirements we need you to heed before we drop off your container at the site.


Why Shipping Containers Make Great Storm Bunkers

Thursday, July 15th, 2021

You probably have seen shipping containers being used for everything from pop-up shops to on-site offices. But did you know shipping containers can be used as storm bunkers? It’s true. Over the years, the shipping container industry has become a big part of disaster management because these units are strong and built to last. They’re not only durable but they’re portable as well, which makes them perfect candidates for storm shelters in areas of the country prone to natural disasters such as hurricanes, tropical storms and tornadoes.

Steel shipping containers are manufactured to withstand rain, wind, snow, and ice, with the ability to endure up to 150 MPH winds. Traditional storm shelters are located underground but there is a trend moving toward above-ground storm shelters crafted out of storage containers. They’re an affordable solution to an otherwise expensive and labor-intensive alternative. Here are the pros and cons to each.

Challenges With Underground Shipping Container Bunkers

While an ingenious, convenient and affordable solution, converting a shipping container into an underground storm bunker isn’t as easy as you may think. Yes, such containers are stackable, but they are designed to bear weight on corner posts — they are not meant to support extreme pressure from all sides. You’ll have to do research to find out if an above-ground or underground shipping container shelter would be best for your needs and region.

Underground shipping containers can handle the elements very well and are the safest place to be in any storm, especially a tornado. But you can’t just bury a couple of stacked shipping containers and expect them not to buckle under the pressure. A container’s strength lies in its solid steel framing, rather than its corrugated-steel side walls. Before putting a container in the ground, it has to be reinforced on the interior and exterior so it doesn’t suddenly collapse or cave-in over time.

When burying a cargo container, you also need plenty of ventilation. You don’t want moisture to build up either. Placing silica bead pouches in the corners can help to retain some of that moisture. If you let moisture go, it can breed mold, which poses a health threat to humans.

Shipping containers made of Corten steel, AKA “weathering” steel, are comprised of rust-resistant steel alloys combined with rust-resistant paint. This combination helps your container better resist harsh weather. You’ll have to make sure the doors of your unit are sealed properly and are wind and watertight (WWT). This makes sense, since storms often bring with them torrential rains. You don’t want that to seep into your underground shelter.

While underground shipping container storm bunkers are certainly a good option, they take more maintenance and reinforcement efforts to ensure they perform safely and efficiently.

What About Above-Ground Shipping Containers?

While underground storm shelters are more common and popular, above-ground steel shipping containers converted to storm shelters may be a better option. These come with no moisture build-up issues, plus they don’t need as much care and maintenance. You don’t need stairs with an above ground shelter, either, making for easier entry and exit by occupants.

When transforming a shipping container into a storm shelter, you’ll have to properly secure the unit to the ground around it. Most steel shipping containers include areas that can be used as tie-downs. You could install anchors in concrete, using a steel cable to secure the container so it remains stable even in the nastiest of storms.

In Conclusion

As you can see, there are benefits and drawbacks to both underground and above ground containers for use as storm bunkers. Regardless of which one you go with, you can’t neglect the planning and research phases to ensure a functional and above all safe storm shelter.

While most shipping container providers don’t actually construct the storm shelters for you, you can purchase the container from them and take it to a contractor specializing in this type of project.

Again, you’ll need to do your research so you’re choosing a professional that has a reputable track record of efficiency and safety.

Shipping Containers: The Difference in Appearance and Condition

Monday, June 28th, 2021

The good, the bad, the ugly: not all shipping containers are created equal. Some are ugly yet still do the job. Others are in pristine condition but you’ll pay top dollar. From one-trip containers to D grade, there are many levels of containers in terms of their appearance and condition.

New/One Trip

These containers have only been used once in international shipping, and were usually built within the last two years. These containers are in excellent condition. You will pay the most for this type but this is a good investment if you need a top-notch container that will be pulling double duty for you for many years.

Cargo Worthy

Cargo worthy storage containers have been inspected and feature a seaworthy certification. If you are planning to ship goods with your container, you’re best off buying a cargo worthy storage container, which has no differences (at least in terms of condition) than a wind and watertight (WWT) container (more on that below).

But this type has the added benefit of being inspected by maritime surveyors, approved for use shipping goods and products overseas. You will pay a few hundred bucks more for this type than WWT simply because of that approval.


This is the most functional and economical solution, and is generally the most affordable cargo box out there. WWT stands for Wind and Water Tight. They range in condition and are in abundant supply. They are used, which means they vary in color, may have some surface rust, and may be dented and dinged.

But they are more affordable because they don’t have to undergo inspection by a maritime surveyor. Sometimes, they can be inspected by an experienced shop personnel at your direction and can be repaired to ensure they are indeed wind and water tight.


As-is containers are sort of like homes being sold as-is – meaning you buy the home/container as it is right now, with no extra work being done on the part of the seller to spruce it up. You’ll likely be looking at some damage which occurred somewhere along the line in the shipping process, as well as structural problems or a lot of rust.

These containers are past the point of being considered WWT. As such, they are much cheaper to buy than cargo worthy or WWT storage containers, but you do have to contend with the damage. This may not matter to you depending on the intended usage, so you can save yourself quite a bit of money here.

Here at Transocean, we have our own system of “grading” our containers. Here’s a look at what each category means.

A Grade

These boxes are in excellent condition, with minimal, if any, rust, good condition doors and gaskets, no major dents, few patches in the roof, and floors in very good condition. Choose this if aesthetics are important to you or you plan to paint the container.

B Grade

With these, you will notice some rust spots but they are mostly superficial in nature – no more than six inches in diameter. You will get good condition doors and gaskets with little to no rust around seals or hinges. You may have to patch a couple of places in the roof or floor, but overall this is a good value as part of a good quality container. Great if you’re planning to use it for storage.

C Grade

Rust, while still superficial, is definitely noticeable yet not predominant. You could see rust spots greater than six inches in diameter. Doors may still function but you may see rust around gaskets, hinges or at the tops of doors. Multiple patches on the roof and floor are likely, with delamination of the flooring as well.

This is our most common and popular grade of shipping container. They’re kind of ugly, but still provide good structural stability.

D Grade

At this level, rust is structural and predominant. You may have a hard time opening or closing doors, and gaskets may be loosening. Severe rust could be accumulating around the seals, with loose floors and severe delamination. Sides often feature large dents or deflections in D grade containers, which can be 20 years old or older. A bit more ugly than the C grade, D grade containers are great for storing 4-wheelers and lawnmowers.

8 Benefits of Modular Construction

Monday, June 14th, 2021

Modular structures can serve as temporary or permanent buildings, extra classrooms, office spaces and more. Using a shipping container or other modular unit for your structure uses fewer materials, takes less time to build and maintains its durability throughout its lifespan. If you’re looking for an easier way to preserve space, time, and money, consider shipping containers and other specialized units.

Check out these eight benefits to modular construction, which can be used for anything from warehouse storage to offices to homes. We hope these tips guide you in making the best possible decision on a modular structure or shipping container near you.

1.  No Impact on Business

If you’re using a modular structure or shipping container for your business, there will be little to no impact on your business operations. They can be set up fast and on-site, which means there’s zero downtime in productivity for you and your staff. This means you can keep making money and serving your customers while saving money and time on construction costs. In fact, you are taking away about 80 percent of construction from your site.

2. Environmentally-Friendly

You’re helping the environment when you use containers and modular structures. Why? They take fewer materials to construct and the materials that are used are sustainable and recycled products. Do your part to reduce your carbon footprint and be eco-friendly with a shipping container unit.

3. Cost Effective

Modular units need less room and less labor to construct, with less time to build as well. This saves you money and time, which leaves you with the most reasonable and affordable payment options.

4. Beautiful

Because you can put them together in any way you choose, and decorate and paint them how you want, modular structures are aesthetically appealing to many people. With newer, more modern designs and colors to choose from than ever before, you can really up the ante when it comes to the beauty of the finished products. The result is a unique structure that will spark conversation among guests and visitors.

5. Flexibility

Modular units are flexible and can be used for a variety of purposes. Not only can you choose the size you want, you can even attach the main structure to an existing business space, garden, property, home or building so you can add more square footage to your usable space at a fraction of the cost of traditional construction.

You can grow in size as quickly or as slowly as you want, using the container for any purpose such as:

  • Job Site Offices
  • Barriers
  • Construction Site Storage
  • Storm Bunkers
  • Garden Shed
  • Hay Storage Barn
  • Firework Stands
  • Inventory Storage
  • Sports Equipment Storage

This flexibility draws many people to storage units and other modular structures.

6. Mobility

Storage containers are adaptable and mobile, meaning you can use them for virtually any purpose, plus you can move them wherever you want to suit your needs. Their adaptable nature make these containers an attractive choice for many job site foremen, real estate agents and others who have to constantly pick up and move their headquarters as their jobs demand.

7. Durability

Modular structures and storage containers are crafted from strong materials, such as Corten steel, that are able to withstand environmental or physical demands, such as wind, rain, and snow. If you live in an area where the weather can change rapidly and tends to be very harsh, this is a great choice for a structure that can take all the abuse Mother Nature can throw at it.

8. Fewer Labor Costs

Yet another benefit of shipping container structures is the associated reduced costs for construction labor. With a modular building, there’s also not as much maintenance or need for renovations as a traditional building would pose. This naturally saves you money on labor and construction costs. If you’re looking to protect your bottom line, a storage container or modular structure would be the way to go.

The above benefits make modular structures a wise choice over traditional buildings.

Your Guide to Shipping Container Maintenance

Tuesday, June 1st, 2021

Even the highest quality shipping containers need some amount of maintenance on a regular basis to ensure a long lifespan. From being mindful of how heavy your stored items are to clearing debris from the roof every now and then, here are some tips on how you can properly maintain your new or used shipping container, no matter what its purpose.

Buy From a Reputable Company

When considering shipping container companies, it’s imperative that you do thorough research. Not all companies are the same. Some have more years of experience than others, while some only offer certain services and not a comprehensive list. Some have great reviews across the board, while others may seem sketchy.

You want your shipping container to last the test of time, obviously. That starts with purchasing the unit from a reputable source. Be aware of the various types of containers you can buy. For example, there are two types of used shipping containers: “one-trip” and “used.”

“One-trip” containers are those that have been in the ocean just once as they traveled overseas to your destination. “Used” containers may have made several transocean trips, and usually feature more wear and tear than one-trip containers. The level of maintenance you give your container will depend on which type it is.

Be Aware of Weight

You may think that just because you have a lot of room in your storage container that you can pile it high with heavy stuff. Not so. It’s best not to store lots of heavy objects in your container. By the same token, you want to lessen the amount of weight on your roof, so never store heavy objects up there either.

Shipping containers tend to support the bulk of the weight at the four corners, which is why you don’t want to place a heavy object across the roof. If you absolutely need to store stuff up top, make sure the bulk of those objects lands on the corners.

Clear Debris, Water, Ice or Snow Off the Roof

On a regular basis and particularly after a storm, clear debris from the top of the roof to avoid cave-ins. Anything from standing water and leaves to snow and ice can weaken the Corten steel material. Eventually, it will rust and get thinner. After extreme weather, take a look at the roof and make sure you get off all debris.

Perform Climate Control System Maintenance

Following your manufacturer’s recommendations, perform regular system maintenance on containers with AC units. Be sure to change the filters, and hire a professional to tackle all maintenance, service or repair issues that may crop up.

Inspect the Container For Rust, Dents, Scratches, and Moisture

You can place your shipping container in the most protected place possible and it will still be vulnerable to rust, dents, scratches and moisture. Taking care of these problems when they first occur will ensure they don’t worsen and lead to bigger, more costly problems. Set up a schedule to inspect the unit, such as once every couple of weeks or every month, then stick to it.

Keep Dust and Rust at Bay

Be sure to remove any accumulating dirt and rust you may notice on the exterior of your container. Give it a good wash, using basic commercial soap and water, or even a mild bleach, and a hose. Use a broom beforehand to get off loose, dry debris. If you see large rust spots, call a professional to remove it so they don’t lead to holes.

Replace Caulking and Weather Stripping Annually

Moisture can have disastrous effects on your container, especially if left to sit. If you had caulking or weather stripping in the corners before, you should check on that every once in a while. If it starts to crack or peel, replace the caulk or weather stripping to ensure a longer life for your container. Plus, it will help your climate control system become more efficient.

There are many ways you can maintain your shipping container, as seen above, so that it lasts as long as it was intended to.
