Galvanized steel , immersing the thin steel plate in the molten zinc bath, adhering a layer of zinc thin steel plate on the surface.It is mainly produced by 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 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 coil has good paint adhesion and weldability.
