Galvanized coil, a thin steel plate is immersed in a molten zinc bath so that a layer of zinc adheres to the surface. It is mainly produced by the continuous galvanizing process, that is, the rolled steel plate is continuously immersed in a plating bath containing molten zinc 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 coming out of the tank to form an alloy film of zinc and iron. This kind of galvanized coil has good paint adhesion and weldability.
