Galvanized steel coil, immersing the thin steel plate in the molten zinc bath, and adhering a layer of zinc thin steel plate on the surface. It is mainly produced by the continuous galvanizing process, that is, the coiled steel plate is continuously immersed in the zinc-melted plating tank to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also made by the hot-dip method, but it is heated to about 500 °C immediately after exiting the tank to form an alloy film of zinc and iron. This galvanized steel coil has good paint adhesion and weldability.

Galvanized steel plate is divided into ordinary electrolytic plate and fingerprint resistant electrolytic plate.Fingerprint resistant plate is added on the basis of ordinary electrolytic plate with a resistant fingerprint treatment, which can resist sweat. It is generally used in parts without any treatment. The brand is SECC-N.Ordinary electrolytic board and phosphating plate and passivation board, phosphating is more commonly used, the grade is SECC-P, commonly known as P material.Passivating plates are oiled and unoiled.
