The galvanized steel coil is immersed in a molten zinc bath to adhere a zinc-plated steel sheet to the surface. At present, it is mainly produced by a continuous galvanizing process, that is, a steel coil is continuously immersed in a zinc-plated plating tank to form a galvanized steel sheet. An alloyed galvanized steel sheet. This steel sheet is also produced by hot dip, but immediately after it is taken out, it is heated to about 500 ° C to form an alloy coating of zinc and iron. This galvanized roll has good adhesion and weldability of the coating.
