PROBLEM TO BE SOLVED: To provide a coating material for highly corrosion-resistant zinc-based alloy-plating, hardly causing difference in color with the zinc-based alloy plating, and securing the adhesion of the coating material with the plated steel material while keeping the corrosion resistance against an iron surface; and to provide a steel-made structure. SOLUTION: The coating material for the highly corrosion-resistant zinc-based alloy-plated steel material contains≥60 mass% zinc-based alloy powder which is a composition comprising≥10 and <30 mass% aluminum and the remainder consisting of zinc and unavoidable impurities. The shape of the powder is sphere or oval regulated so that the ratio (the maximum diameter/the minimum diameter) of the maximum diameter to the minimum diameter is 1-1.5. The steel-made structure is obtained by using the coating material. COPYRIGHT: (C)2006,JPO&NCIPI |
