Since the two-layered galvanized steel sheet of zinc and zinc-manganese alloy prepared by the present invention has much better corrosion resistance and adhesion than conventional plated steel sheets, it can be used more appropriately for products requiring high corrosion resistance such as automobiles, home appliances and building materials. It can be effective.
