This specification  covers zinc coatings applied by the hot-dip process on iron and steel hardware.

The hot-dip galvanizing process consists of parts being immersed in molten zinc for a sufficient time to allow a metallurgical  reaction between iron from the steel  surface and the molten zinc, resulting  in the formation of Zn/Fe alloy layers bonding the coating to the steel surface.
