ASTM A653M specification covers steel sheet, zinc-coated (galvanized) or zinc-iron alloy-coated (galvannealed) by the hotdip process in coils and cut lengths.
Galvanized sheet refers to the steel plate coated with a layer of zinc.Galvanizing is an economical and effective antirust method which is often used.
