Performance indexes of coating The most important performance of hot-dip galvanized products is the coating performance, mainly referring to the corrosion resistance and adhesion of the coating. The corrosion resistance includes salt spray and moisture resistance, etc., and the adhesion of the coating refers to the performance of the product to resist cracking, peeling, powdering, etc., during the processing of the coating.

Other performance indicators No test can perfectly match actual usage conditions. Other important performance aspects include surface quality, such as the surface quality of car exterior panels and appliance outer surfaces. For the automotive industry, controlling the surface roughness of steel plates is also crucial. Defining surface quality cannot be fully explained in just a few words; the best approach is to avoid direct use during different applications and conduct verification first. Additionally, there are other considerations, like for alloyed products or ordinary hot-dip galvanized products, which may have cut edges or uncut edges. Uncut edge steel sheets are allowed to have minor zinc layer cracks and white edges at their edges.
