Step 1: Examine and Repair the Container Roof The first and most significant part of the container to maintain is the roof of your shipping container. Second-hand containers are often dented when having other containers loaded on top of them. Dents can gather rain water which causes corrosion. Ensure that all dents are fixed and areas are treated with rust proof paint to avoid corrosion. Step 2: Check, Remove and Treat Rusted Areas Many shipping container websites mistakenly suggest that because shipping containers are constructed from Cor-Ten steel that they are totally rust proof. This is not the case – Cor-Ten steel is better to other steel, and corrosion resistant, but not completely corrosion proof. The steel is sensitive to salt air environments and must be preserved to guarantee that it does not rust with specialist paint. Areas that have been dented, scratched or cut must be sealed, painted and rust proofed. Step 3: Inspect, Lubricate and Repair Doors Shipping containers are fairly simple, and only have a couple of moving parts in the door assemblies. As with everything with moving parts, they are subject to damage or wear out with frequent use, and should be looked after to ensure they work properly all the time. There are two important things to do when maintaining your shipping container doors. The first is to clean them, and the second is to lubricate them. Step 4: Check container alterations Shipping containers are well designed to evade corrosion, water and dirt traps. Things get a little bit fiddlier after you cut them, join them, stack them and modify them in numerous ways, shapes, and forms. This is especially vital if you have used shipping containers as the basis for a modified container building with doors, windows and other openings. Check your containers altered areas, especially around the joints or metal on metal areas to confirm that these are clean and free of corrosion. Take special care to look for depressions or other areas that may amass dirt, debris, and water and clean them out. Remove any rust and treat the area with anti-corrosive paint. Step 5: Make sure the Container is on a Level Surface One of the most imperative things you can do to ensure a long life of your shipping container is to mount it on a level, well-drained surface. This stops water from collecting in one area of the container and prevents corrosion of the underside.
