Hot dipped galvanized steel coils are steel coils that have been zinc-coated using the hot dipped galvanizing process. Steel coils are immersed in a molten zinc bath, which establishes a metallurgical bond with the steel substrate. This results in a protective zinc coating that helps prevent corrosion and increases the steel’s lifespan. The hot dipped galvanizing method produces a long-lasting, homogeneous coating that protects the steel coils evenly across their full surface. Because of their corrosion resistance and strength, hot dipped galvanized steel coils are widely utilized in a variety of industries, including construction, automotive, appliances, and manufacturing. Among them, being mainly used for roofs, doors and windows, shutter doors, ceiling keels, etc in the construction industry. Being used in refrigerators in Home appliances, washing machines, etc. Being mainly used for body shells, chassis, doors, fuel tanks, fenders, etc in the automotive industry. Being mainly used for steel window blank, color coated plate substrate and so on in the metallurgical industry.
