Because shipping container doors are an integral part of the container structure, selecting the right door not only helps keep your contents safe but also makes storage containers more accessible and easier to use.
Choosing the right doors is also an important consideration during the design process.
If you're using a shipping container with pre-built doors, knowing the door architecture can help troubleshoot any issues that may hamper the container's accessibility.
Let's look at the design, construction, and types of doors that will give you maximum flexibility for your desired application.
For every storage container door there are five essential components:
The body of a cargo door features two vertical hollow leaves, two horizontal C-sections, and a frame consisting of infilled, corrugated steel paneling.
Four drop-forged steel hinges help hold the body at the rear corners of the container. The hinges, also known as blades, allow the door to swing 270 degrees against the container wall.
A lockbox is a protective steel box welded directly onto the door that houses a padlock. It protects the items inside the container from theft, tampering, and break-ins.
Each door has two to four vertical lock rods that enable opening, closing, and locking. The lock rod has a welded cam-and-knuckle mechanism, known as the cam keeper. Whenever you open the door, the handle rotates and forces the cam out of the keeper.
Rubber gaskets close the gap between the door body and the edges of the container. This seal helps prevent water ingress and leakage, keeping contents safe from damage.
Door hinges act as pivot points on the door, allowing free rotational movement.
Some containers may also have additional utilities, such as a security swing arm and shackle-puck locks.
With the proper equipment, fitting cargo doors can be a DIY process.
Due to the weight of the doors, you’ll most likely need a forklift or hoist mechanism in order to lift them.
Otherwise, it’s best to hire a professional. Before you start, you’ll also want to ensure that you have the following tools:

Depending upon your needs, you can use the following standard door types:
Cargo doors are heavy-duty free-swinging doors located at one end of the container. They are ideal for the portable storage of tools, machinery, and valuable items, however, they can be challenging to access in constrained spaces.
For portable offices, workspaces, and living areas, personnel doors are a necessity for convenience. If your services require frequent container access, these doors are the best solution for your company.
Roll-up doors, or shutter doors, lift from the bottom and curl up inside the container. These doors are a must if you lack adequate space around the storage unit.
Glass doors are an aesthetic option for container cafes, shops, and exhibition areas. These stylish doors are transparent, enabling maximum light into the unit. However, they might not be as secure as the options mentioned above.
