Common Repairs to Shipping Containers

Today, retired shipping containers are used for almost every type of living environment that you can imagine. These giant metal boxes have to face many harsh elements and severe climatic conditions before they get to retire to their next life. Investing in a shipping container is one of the most profitable types of business. Because by making some minor adjustments and modifications, you can turn these cargo containers in a productive building or storage houses.

We know that shipping containers are sturdy, robust, and durable as they are made from high tensile Corten (anti-corrosion) steel. This makes them able to survive under extreme climatic conditions. However, they get deteriorate with rusting, scratching, and denting with every passing year and need regular repairs and maintenance. So, the proper maintenance of the storage containers is the vital key to get the return on your investment.  

Experience shows that most companies and contractors prefer to replace damaged shipping containers instead of repairing them. But some minor repairs can also save you thousands of bucks.

Well, if this is the case, you should have to fix minor damages immediately to avoid shelling out cash for big repairs. Fixing them before spreading them all over the structure will help to save your money as well as your cargo container.

Here are a few simple repairs to storage containers that you can handle on your own.

  1. Door Repairs:

The container doors become stiff and harder to open after years of use. Because of consistent closing and opening of doors, the hinges got wear down. Attempting to open the doors forcefully will result in scratches on the floor, and will often tear the hinges apart. Moreover, the locking bar handles can also be stuck or broke, and it gets difficult to open them easily. 

 To fix these problems, the hinges must be oiled regularly, and locking bar handles should be replaced with new ones. Always go with the smart repair, and your storage box won't get damaged easily.

  1. Repaint the Container to avoid Rust/ Dealing with Rust

Steel made containers act as big magnets for rust. This is because they are usually stacked up out in the open place and continuously exposed to different toxic elements that can corrode the material. Thus, it needs to be fixed right away before it affects the other parts of the Container. 

 The best way to protect your cargo container is to use water-resistant paint that will stop the process of rusting and expand the life-span of your Container. You should also start the cleaning process as soon as you see rust starting to form anywhere on the storage box.

  1. Patch small holes

When rust leaves little pinholes on your container top, you'll have to do something about it. If the damage is confined to a small area, metal patches can be welded over the scratched areas. That is a viable solution if the holes are only in a small area. However, if your problem is bigger than that, you are in trouble. Now, you have to cut down that part of Container having a big hole, and replace it with more Corten steel. An expert welder can quickly fix this issue and can correctly do patching. These waterproof patches can also bond to rusty surfaces and resistant to extreme temperatures.

  1. Fixing Roof Concerns

The roofs of the cargo containers have a weak link in the whole structure, and they have the minimal load-bearing capacity. Shipping container roofing is corrugated sheet metal that drains water from a small side to side pitch. Shipping containers may often get a scratched roof due to handling while being loaded or unloaded from cargo ships. When you find a large tear or another form of opening during an inspection in your container roofing material, you will have to fix it with patches, or you can make full tear off by replacing the roof.

Checking the roof status frequently is always a good idea to be sure it has not incurred any damage. If this is the case, repairing the damage should be given a priority.

  1. Replace the Floor

 A storage container floor takes up the bulk of the weight and can get damaged easily. The floor of your cargo box has two parts: one is the top layer made of marine-grade plywood, and the bottom layer is made up of steel. If the plywood layer rots out or simple cracks, you can replace it. However, if the steel made layer also rotted away, you need to replace the whole Container.

When buying storage boxes, most of the people forget to look down, which is a big mistake? The best-looking shipping container becomes useless when a small hole on the floor turns into a large rip and left unrepaired. So, it is essential to do a regular inspection of the bottom layer and check the steel-cross from time to time.

Keep closed the doors of storage containers when they are not in use. This will inhibit the moisture from entering the box and will not rot the plywood floor.


So, these are some common repairs that you take to extend the life of your shipping container. Whether you are renting or buying a portable storage container, these repairing tips will greatly help you, and you can fix the problem in time. However, regular maintenance is also crucial to avoid any future mishap. You also need to perform the routine checks and inspections to keep maintain the health of your Conex box.
