Factory Direct Price ASTM A653 G90 Z275 g Dx51d Galvanized Coil.Hot-dip galvanized coils can therefore be divided into hot-rolled galvanized coils and cold-rolled hot-dip galvanized coils. They are mainly used in construction, home appliances, automobiles, containers, transportation, and other industrial fields, especially in steel structure construction, automobile manufacturing, and steel silo manufacturing. Their main characteristics include: strong corrosion resistance, good surface quality, suitability for further processing, and economic practicality.
