Steel is made from iron and some other components; since steel is made of iron, it is a ferrous metal. Ferrous metals are prone to oxidation or rusting in the presence of oxygen and moisture. They also can corrode over time. To prevent that from happening, the steel is galvanised. Galvanising steel involves applying a protective coating of zinc over the door Zinc is a non-reactive metal that does not rust or corrode even when it is rained on repeatedly. This means that the galvanised steel roller shutter doors will not rust over time. They will always be protective of your warehouse.

Furthermore, the doors are typically on rollers that are also made of metal Your rollers need to be made with galvanised steel tracks.

In the event the underlying metal becomes exposed, protection can continue as long as there is zinc close enough to be electrically coupled. After all of the zinc in the immediate area is consumed, localized corrosion of the base metal can occur
