Hot-dip galvanizing is the process of immersing iron or steel in a bath of molten zinc to produce a corrosion resistant, multi-layered coating of zinc-iron alloy and zinc metal. While the steel is immersed in the zinc, a metallurgical reaction occurs between the iron in the steel and the molten zinc. This reaction is a diffusion process, so the coating forms perpendicular to all surfaces creating a uniform thickness throughout the part.

The hot-dip galvanizing process has been used since 1742

Forgings require fewer secondary operations. As supplied, some grades of bar and plate require additional operations such as turning, grinding, and polishing to remove surface irregularities and achieve desired finish, dimensional accuracy, machinability, and strength. Often, forgings can be put into service without expensive secondary operations.
