SuperBox provides various customization options for shipping containers, making them suitable for a wide range of uses, whether for personal or business purposes. Below are some of the most popular modifications you can select from:

You can paint the outside of your container too. This is great if it will be in a public space or if you want it to match your business branding. It also helps protect against weather damage and rust.

A fresh coat of paint on the inside of your container not only improves its look but also protects against rust and brightens up the space, especially if you’re using it as an office or living area.

A roll-up door makes it easier to load and unload large items. It’s a great option for containers used for storage or as workspaces where easy access is important.

A smaller personnel door makes it easy to get in and out without opening the big cargo doors. This is perfect for containers used as offices or workshops.

Adding windows lets in natural light and improves ventilation. It makes the space feel more comfortable, especially if you’re turning the container into an office, studio, or living space.

We can add wiring, lighting, and outlets to your container, making it ready to use as a workspace or living area with power for lights, tools, and more.

We offer different types of shipping containers: New/One Trip, Used, CWO (Cargo Worthy), and WWT (Wind & Water Tight). Unlike other companies, we don’t sell containers “as is” because we believe in providing quality options. We recommend avoiding “as is” containers, as they may have hidden problems that could cause issues later. Our goal is to give you a container that’s in good condition and built to last.

New/One Trip containers are almost brand new. They’ve only been used once to ship goods across the ocean. They might have minor dents or scratches but are still in great shape. These containers are made in Asia, and since they’ve only been used for one trip, they cost less, saving you money. If you want a container that’s close to new, this is the best option.
Used shipping containers have been used to ship goods worldwide. After their initial use, they’re sold at a lower price, making them a great, affordable choice for storage. They may have signs of wear, like dents, rust, or faded paint, but they’re still strong and durable. Many people use them for storage or turn them into offices, homes, or workshops. They are a budget-friendly and practical option.


Cargo Worthy (CW) containers are inspected and certified for international shipping by sea, rail, or road. They might have some signs of use, like old paint or dents, but they’re still safe and reliable. These containers must pass a safety inspection and show a valid CSC (Container Safety Convention) sticker to be approved for global shipping.
Wind & Water Tight (WWT) containers are built to keep out wind and water, making them great for protecting your goods. They may have some wear, like faded paint or rust, but they are designed to keep everything inside dry and safe. While they might not look as new, they are still a reliable option for storage.

We offer a range of steel storage containers in various sizes to suit your needs. The best container for you will depend on what you’re storing and where you plan to keep it. You can choose from standard containers or high cubes based on your specific requirements.
The standard container is the most common type. It’s fully enclosed and weatherproof, making it ideal for transporting regular cargo that doesn’t need temperature control. These containers come in sizes like 20′, 40′, or 45′ and are perfect for securely storing and moving goods.

A double door or tunnel container looks like a standard dry van but features doors at both ends. This design makes loading and unloading easier, especially when you need access from both sides. Tunnel containers are particularly useful when you need to quickly reach your cargo or when containers are stacked and need to be accessed from different angles.

Open-top containers have a removable tarp or canvas roof instead of a solid metal top. These are used for large or awkward items that can’t be loaded through regular container doors, such as heavy machinery or construction materials. They are typically loaded from above using a crane or forklift.

Open-side containers have doors that open along the entire side, providing easier access for loading and unloading large or wide items. This is especially helpful for businesses that need to move bulky goods like furniture or construction materials. These containers offer side access rather than the traditional end doors.

The 20′ container is a popular choice for extra storage without needing the size of a 40′ container. It measures 20′ long, 8′ wide, and 8′ 6″ high, with a rear door for easy access. The floor is wooden, and the walls and roof are made of strong steel. It’s perfect for smaller storage needs.

The 20-high cube container is a great option for businesses, offering extra height with a 9′ 6″ ceiling. Made from durable steel, it weighs around 5,000 pounds and has a rear door for easy access. The extra height is ideal for storing larger items, and it’s built to last and resist weather.

The 40′ container is widely used by businesses. It weighs about 8,270 pounds and has a standard height of 8′ 6″, with a rear door for easy access. There’s also a taller version, the 40-high cube, which stands 9′ 6″ high. These containers are strong, weather-resistant, and perfect for storing business equipment and goods.

The 40-high cube container is a taller version of the standard 40′ container, offering more interior space with a height of 9′ 6″. This extra height makes it great for storing larger or bulkier items. If you need more storage room, the high cube is a solid choice.

For those needing even more storage space, the 45′ container offers additional length and is made from durable steel. It has a rear door for easy access and is weather-resistant. While not typically in stock, we can source one for you upon request.
If you need to store items that require a specific temperature, refrigerated shipping containers (reefers) are the ideal choice. These containers keep your goods cool or frozen, making them perfect for businesses that deal with perishable items. We offer 20′ and 40′ refrigerated containers for both short-term and long-term use.
Reefers protect your goods from moisture, pests, and temperature changes while keeping a consistent climate. Whether you’re storing food, pharmaceuticals, or other sensitive products, reefers help ensure they stay in good condition.

These containers have a fully operational refrigeration unit that can cool or freeze your items. They’re great for businesses that need to keep goods at a specific temperature over time, like food storage or medical supply transport. The cooling unit is powered and keeps your items fresh.
These are used or damaged reefers with a broken refrigeration unit. They don’t provide temperature control but still offer dry storage space. Non-working reefers are ideal for businesses that just need extra storage, without the need for cooling. They are more affordable and can be used for general storage or temporary shelters.
