Bonderized steel is actually Galvanized steel that has been put through a phosphate bath and has a layer of Chromate applied and dried. The process produces a dull gray colored finish which provides for a good primer in order to be painted.
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.
