New Shipping Containers

Our new shipping containers are one-trip containers, meaning they are only used once before reaching their destination. They were manufactured, loaded with cargo, shipped, and unloaded before they reach our depot. Since these new shipping containers have been handled in the port, they will only have a few minor dents and scratches.

Used Shipping Containers

Our used containers have been transporting goods all around the world for years. They are inspected and kept up to compliance standards because these cargo containers are very durable and designed to be long-lasting. If you need a quality, long lasting shipping container but do not want to spend as much on it, our used shipping containers will be perfect for you.

Standard containers are 8 feet 6 inch tall and High Cube containers have an additional foot of headspace at 9 feet 6 inch.

There are 3 relevant weights to consider which are painted on the outside of the container doors.

  • The container tare weight is the weight of the container without any contents.
  • The container gross weight is the weight of the container + the maximum payload it can hold. In other words, the maximum total weight of the container.
  • The payload (net weight) is the weight of the cargo or contents that a container can hold.

The weight of an empty shipping container (tare weight) varies by size. 20ft containers weigh about 5,000 pounds. 40ft standard and high cube containers weigh around 8,000 pounds.

We sell containers to individuals, small businesses, large corporations, the government, and the military. We provide containers to everyone through a seamless and hassle-free process.

This could be due to several reasons. New containers sometimes have a paint or chemical smell because the doors have been closed for 99% of the time since being built with minimal air circulation. We recommend leaving the doors open for a few days to let it air out or purchasing industrial strength odor neutralizers from your local hardware store.

There are thousands of ways to use shipping containers. In fact, there is no limit to what a shipping container can be used for. With a little creativity, they can be transformed into almost anything. Almost every industry uses them in some way including industrial, commercial, and personal uses.

  • Temporary workspace: Containers are used by businesses that need to quickly set up or break down a temporary workspace. And because they’re made from sturdy steel, they can handle the rigors of being moved and transported multiple times without any damage.
  • Storage: They can be used to store supplies, equipment, and even hazardous materials. They can also be used as temporary storage space for excess inventory or materials.
  • Transporting goods: Containers are often used to transport goods from one location to another. They can be used to store or transport items in a warehouse setting, or they can be taken on the road and used as a mobile storage unit.
  • Industrial Uses: There are many industrial applications including workshops, toolrooms, confined space training, and more. They can also be modified to be employee housing on a jobsite.
  • Container homes: Need portable and affordable housing options? Shipping containers can be modified to include basic facilities like a bed, bathroom, and kitchen, and they can be transported virtually anywhere. People use them as homes, studios, or extensions to their homes. They are also converted into barns, sheds, camp houses, and even mancaves.

Start by greasing the door hinges with an industrial lubricant for ease of use. Prevent the container from settling and causing an uneven doorframe by placing wood blocks under the doorframe posts. If the container has settled, the doorframe will be uneven, causing the door to not open and close properly.

Follow this simple checklist to maintain your container structure:

As Needed:

  • Remove heavy debris, ice, snow, and standing water from roof immediately.
  • Remove visible dirt to prevent damage to paint which can lead to rust.
  • Maintain level flooring, so the structure does not weaken.

Annual Checklist:

  • Inspect for peeling paint and ruse. Repaint rust patches as needed to maintain a weatherproof seal.
  • Inspect caulking and weather stripping on doors and windows for leaks and replace as needed.
  • Inspect the leveling of the container. Some settling of the foundation and the container is normal. Re-level if necessary.
  • Inspect roof for dents and debris. Fill major dents with a sealant, such as caulk, to prevent further damage.
  • For climate-controlled shipping containers, check for mold and clean the AC unit by replacing the filter.

Standard container doors are approx. 7 feet, 8 inches but there are many other custom door options.

Yes, shipping containers are designed to be waterproof. Their structure, typically made from weathering steel (also known as COR-TEN steel), is designed to withstand harsh weather conditions, including heavy rains. The doors are equipped with watertight seals that prevent water ingress, thus ensuring that cargo housed within remains dry and safe during transit. However, a container may lose its waterproof quality over time and with wear and tear, so regular maintenance and inspection are necessary.

While it is true that shipping containers are designed to be waterproof, it’s crucial to note that not all containers are created equal, and their waterproofing levels can significantly vary. Factors such as the container’s age, condition, and quality can greatly affect its ability to withstand water. Older containers or those that have been poorly maintained may have lost their watertight integrity, with the presence of rust and damage to the seals being potential indicators.

Furthermore, while shipping containers are intended to be waterproof, it’s important to understand that they are not necessarily designed to be completely airtight. While the doors are equipped with seals to prevent both water ingress and the entry of pests, these seals do not make the container hermetically sealed. Air can still enter and exit, especially in older containers where the seals may have worn away over time.

Delivery Questions

Shipping containers are self-supporting and do not need any special foundations, but it’s important to place them on level ground to help ensure functionality and longevity. The container should ideally be positioned on a flat, level surface. If the ground is uneven, consider using materials such as railway sleepers or concrete paving blocks underneath each corner to level it. A well-placed container allows the doors to operate correctly and can hold up to approx. 30 tonnes of load without any issues.
