Summary:PURPOSE:To obtain the plated coating object having a smooth plating surface by maintaining the temp. of a plating bath in a specific range. CONSTITUTION:Iron and steel products are immersed into the bath contg. 0.10 to 10wt.% aluminum and 1.5 to 10wt.% copper and the balance consisting of zinc aside from inevitable impurities, by which the zinc aluminum alloy plating is applied on the surfaces thereof. The temp. of the plating bath is maintained in the range exceeding the solidification initiation temp. of the bath by 65 to 140 deg.C. As a result, the easy plating is executed without limitation even in such a case handling time is required and long-term immersion is involved as in large-sized steel products. The plated coating object having high practicability is thus obtd.
