Product Description
Hot Dipped Galvanized Steel Coil
Galvanized steel coil is manufactured by immersing thin steel sheets into a molten zinc bath, creating a protective zinc coating on the surface. Produced through continuous galvanizing processes, these coils offer excellent corrosion resistance and superior surface quality, making them ideal for various industrial applications.

Manufacturing Process
Using cold-rolled or hot-rolled steel strip as the substrate, the material is immersed in 450-460°C molten zinc liquid. An iron-zinc reaction forms a durable alloy layer, which is then covered with a pure zinc layer. The process concludes with cooling and post-processing treatments such as passivation and oiling to ensure optimal performance and longevity.
Industry Applications
Widely used across multiple industries including construction (steel structures, roof panels), home appliances (refrigerator shells, washing machine inner drums), automotive (chassis anti-corrosion, exhaust pipe sheaths), energy (photovoltaic systems), and container manufacturing.
