Galvanized steel coil is a type of steel coil that has undergone surface galvanizing treatment. It is coated with a layer of zinc on the surface of a substrate (such as cold-rolled or hot-rolled steel plate) to improve its corrosion resistance and service life. The galvanizing process mainly includes two methods: hot-dip galvanizing (hot-dip galvanizing) and electroplating galvanizing. Among them, hot-dip galvanizing is more common, with a thicker zinc layer and stronger protection.

• Excellent corrosion resistance, zinc has more reactive chemical properties than iron and will preferentially react with oxygen and water vapor in the environment to form a dense oxide film. The service life of galvanized steel plates can reach 10-50 years, far exceeding that of ordinary steel plates.
• High cost-effectiveness and low cost anti-corrosion: Compared with stainless steel or other alloy steels, galvanizing process has lower cost, but can significantly improve the durability of steel plates and reduce maintenance or replacement costs.
• Good processing performance, galvanized steel sheet can be processed by cutting, bending, welding, etc.
• High strength and lightweight, different strength substrates (such as low carbon steel and high-strength steel) can be selected according to needs.
• Aesthetics, the galvanized layer presents a silver gray luster, neat and beautiful, suitable for exposed use occasions.
• Environmental friendliness and recyclability: Galvanized steel plates are 100% recyclable, and zinc itself is also a reusable resource.
