Shipping container doors are an integral part of the container structure. Selecting an appropriate door not only helps keep your contents safe but also makes storage containers more accessible and easier to use.
While designing cargo containers, choosing the right doors is an important design consideration. Additionally, 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 you can opt for to get maximum flexibility for your desired application.
The five essential parts of every storage container door are:
The body of a cargo door features two vertical hollow leaves, two horizontal C-sections, and a frame consisting of an infilled, corrugated steel paneling.
Four drop-forged steel hinges help hold the body at the rear corners of the containers.
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 on the door that houses a padlock. It protects the items inside the container from theft, tampering, and break-ins.
Each door has 2-4 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 help close the gap between the door body and the edges of the container. As a result, they help prevent water ingress and leaks to a certain extent.
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:
These are heavy-duty, freely swinging doors located at one end of the containers. They find their application in portable storage containers that store tools, machinery, and valuable items but can be challenging to access in constrained spaces.
Personnel doors help add more convenience, especially in portable offices, workspaces, and living areas. If your services require frequent container access, these doors can be the best solution for your company.
Roll-up doors or shutter doors lift from the bottom and curl up inside the container. If you do not have adequate space around the storage unit, you must go for these doors.
Glass doors are an aesthetic option for container cafes, shops, and exhibition areas. These stylish doors have a transparent body that enables maximum light to enter inside the unit. However, they might not be as secure as the options mentioned above.
There can be multiple entryways in large office-storage combo containers, each having a different door for easy access. Shipping container modification generally consists of creating various entries according to your business needs.
