It is a steel product, mainly made of carbon steel.In the manufacturing process of galvanized steel strip, different grades of steel will be used, including low carbon steel , medium carbon steel and high strength steel , etc. These kinds of steel have different physical and chemical properties, such as hardness, strength, toughness, etc., to meet different application needs. Galvanized steel strip is plated with a layer of zinc on the surface of cold rolled or hot rolled long steel sheet. The formation of new building materials with corrosion resistance, wear resistance and aesthetics, galvanized layer can significantly improve the service life of steel strips, especially in harsh environments or corrosive environments.
