Electro cold rolled Zinc coated galvanized steel coil is a kind of metal product which uses cold rolled steel sheet as the base material and forms a dense zinc layer on its surface through electro galvanizing process. The product has both the strength of steel and the corrosion resistance of zinc layer, with excellent anti-corrosion performance and good processing and forming properties. At the same time, it has smooth surface, uniform color and excellent aesthetic effect. The raw materials are mainly high-quality cold rolled steel sheets, which are pre-treated with surface cleaning, degreasing, pickling and other pre-treatment processes to ensure the cleanliness and activity of the steel sheet surface. Subsequently, a zinc layer is deposited on the surface of the steel plate through the zinc electroplating process, and finally a dense zinc protective film is formed through passivation, drying and other post-treatment processes. The entire production process is strictly controlled to ensure stable and reliable product quality.
As a high-quality steel base material, cold rolled steel coil has high strength, good formability and welding performance. After electro-galvanized treatment, it not only retains these advantages, but also further improves its corrosion resistance and aesthetics. In addition, it has excellent processing properties and can be easily cut, bent, stamped and other processing operations. Its zinc layer has excellent corrosion resistance and can effectively resist erosion by corrosive media in the environment of atmosphere, water and soil. At the same time, the zinc layer has a smooth surface, uniform color, with good aesthetic effect. Through passivation treatment, the corrosion resistance and adhesion of the zinc layer can also be further improved to extend the service life of the product.
