标准摘要
Zinc and zinc-alloy coated steel is used to enhance a structure’s protection against corrosion degradation. For the purpose of this SAE Recommended Practice, a galvanized coating is defined as a zinc or zinc-alloy metallic coating. The selection of the optimum galvanized steel sheet product depends on many factors, the most important being: desired corrosion protection, formability, weldability, surface characteristics, and paintability. The trade-offs of these product characteristics are more complex than is the case with uncoated steel sheet products.Cross Reference: ASTMA653/A653M,ASTMA754/A754M,ASTMA879/A879M,ASTMA90/A90M,ASTMA924/A924M,J1392_201703,J2329,J2340_201703,J2745
