Galvanized steel coil is a kind of thin steel sheet dipped into a bath of dissolved zinc so that it sticks to a layer of zinc on the surface. At present it mainly uses continuous galvanizing process which is to immerse steel coils in zinc dissolved tank continuously to produce galvanized steel sheets and to alloy galvanized steel sheet.This kind of steel sheet is made by hot dipping,and heated to 500ºC mmediately after it come out of the zinc tank to form an alloy film of zinc and iron. It has an excellent coating adhesion and weldabiity.
Advantage of Galvanized steel
1. Excellent corrosion resistance, zinc has more reactive chemicalproperties than iron and will preferentially react with oxygen and watervapor in the environment to form a dense oxide film. The service life ofgalvanized steel plates can reach 10-50 years, far exceeding that ofordinary steel plates.
2. High cost-effectiveness and low cost anti-corrosion: Compared withstainless steel or other alloy steels, galvanizing process has lower cost,but can significantly improve the durability of steel plates and reducemaintenance or replacement costs.
3. Good processing performance, galvanized steel sheet can be processedby cutting, bending, welding, etc
4. High strength and lightweight, different strength substrates (such aslow carbon steel and high-strength steel) can be selected according toneeds.
5.Aesthetics, the galvanized layer presents a silver gray luster, neat andbeautiful, suitable for exposed use occasions6. Environmental friendliness and recyclability: Galvanized steel plates are100% recyclable, and zinc itself is also a reusable resource.
