Shipping containers are undoubtedly becoming the trendiest material in economical, eco-friendly building projects. The fact that you can buy them second-hand and re-purpose them as residential or commercial space to cut building costs makes them all the more attractive. But do you know why they are still so durable even after being used to carry goods across the world?
The answer is simple, they are made with CORTEN steel which is what makes them strong enough to withstand harsh weather conditions.
So what is CORTEN steel anyway?
Corten or COR-TEN steel, also known as weathering steel is a group of steel alloys that were specially designed and developed to eliminate the need to repaint. When a factory manufactures a shipping container, they apply a generous coat of marine paint. This will ensure that the container is protected as it ages and is banged around on a ship or truck in transit, the properties of the steel will then begin to form to create a second layer of defense.
Maintaining a CORTEN steel shipping container
The first thing to do to expand the lifecycle of your shipping container, whether used or brand new is to maintain the roof of the container. Inspect the roof for any dents as shipping containers can have dents when other containers are stacked on top of them. These dents can collect rain water, causing corrosion on the chipped paint. Make sure that all dents are fixed, and you apply rust proof paint to prevent corrosion.
