Galvanized coil: A thin steel sheet is dipped in a bath of molten zinc to coat its surface with a layer of zinc. It is primarily produced through a continuous galvanizing process, where the rolled steel sheet is continuously immersed in a molten zinc bath to create a galvanized steel sheet. Another variant is the alloyed galvanized steel sheet.

This type of steel panel is also produced using the hot-dip method, but it undergoes an additional step where it is heated to approximately 500°C immediately after emerging from the tank. This process forms a zinc-iron alloy coating on the surface. Galvanized coils exhibit excellent plating adhesion and weldability.

Galvanized steel coils and sheet products find extensive usage in appliances, automobiles, industrial machinery, as well as civil engineering and construction applications.
