Galvanizing (or zinc coating) is the process of adding a layer of zinc to the outer surface of a metal, such as steel or iron. The purpose of doing this is to add a protective coating to the underlying metal, reducing the possibility of corrosion or rusting.
The galvanizing process varies depending on the specific technology. However, the most important part of this process is that it usually involves enclosing steel or iron in zinc, which may be in a liquid or dust-like state. When zinc is introduced, the iron in the surrounding metal reacts with zinc to form a tightly bonded alloy coating.
