COATING MATERIAL FOR HIGHLY CORROSION-RESISTANT ZINC ALLOY-PLATED STEEL MEMBER AND STEEL STRUCTURE HAVING COATING FILM MADE OF SUCH COATING MATERIAL

摘要

A paint for highly corrosion-resistant zinc-alloy coated steels containing zinc-alloy powder at not less than 60 mass%, characterized in that said powder contains aluminum at not less than 10 mass% and less than 30 mass% and the remainder comprising zinc and unavoidable impurities, the shape of powder particles is spherical or oval and the ratio between the maximum and minimum diameters (maximum diameter/minimum diameter) is 1 to 1.5, and a steel structure having coated films produced by using said paint.
