PROBLEM TO BE SOLVED: To provide a method of coating a steel product using an aluminum-zinc coating alloy. SOLUTION: A coating bath is modified with a particulate compound constituent in effective amounts to control the spangle facet size of the coated product to improve tension bend corrosive rust characteristics and coated surface appearance when brushed. Constituents include boron compounds such as titanium boride and aluminum boride, carbon compounds such as titanium carbide, and aluminum compounds such as titanium aluminide. The coated steel product that does not require temper rolling for coating is produced by this method. COPYRIGHT: (C)2004,JPO
