Galvanization, or galvanisation, is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanization, in which parts are submerged in a bath of molten zinc.
Galvanization is a process in which metal is coated in a material which will help it resist corrosion. Zinc is classically used for galvanization. The blend of these two processes is designed to give galvannealed steel some unique and very desirable properties which make it ideally suited to an array of applications. In galvanneal, the steel is first dipped in a hot bath of zinc, as is done when materials are galvanized. Then, it is subjected to a secondary process in which iron is annealed with the zinc coating to create an iron-zinc blend on the surface of the metal.
