PURPOSE:To contrive to enhance heat resistance and state of plated surface, by applying a molten plating bath comprising an alloy containing Al, Pb and Zn in a predetermined ratio to the surface of a ferrous metal. CONSTITUTION:A Zn-alloy comprising 0.2-14% Al, 0.01-0.5% Pb and the remainder of Zn is melted to form a molten plating bath in which iron, steel or an iron alloy is, in turn, immersed to apply molten plating thereto. The obtained Zn-alloy plated ferrous metal product is excellent in heat resistance and plated surface state. |
