Abstract

PURPOSE:To manufacture a galvanized steel sheet resisting rust and having superior surface properties by galvanizing a pretreated steel sheet with a galvanizing bath contg. a predetermined percentage each of Al, Pb, Mg and Sn. CONSTITUTION:A steel sheet pretreated by the Sendzimir method or other known method is galvanized with a galvanizing bath contg. <=0.4%, especially <=0.1% Al, <=0.4%, especially <=0.1% Pb, 0.1-3.0% Mg and 0.2-1.2% Sn. By using such a much Mg-contg. bath, high corrosion resistance is provided to the sheet, and a fluidity lowering of the bath due to much Mg added is prevented without sacrificing the corrosion resistance of the sheet. Thus, a high quality galvanized steel sheet resisting rust and having a fine surface is obtd.
