Galvanized sheet is a steel plate with a zinc coating on its surface. Galvanizing is an economical and effective anticorrosive method which is often used. About half of the world's zinc production is used in this process.
1. Definition of
China Galvanized Steel Roofing Sheet for sale is coated with zinc metal to prevent corrosion on the surface of steel sheet and prolong its service life. This kind of thin galvanized steel sheet is called galvanized steel sheet.
2. The classification and use of galvanized sheets can be divided into the following categories according to production and processing methods:
A. The
hot dip galvanized steel coil for sale. The thin steel plate is immersed in the molten zinc bath to make its surface adhere to a layer of zinc thin steel plate. At present, continuous galvanizing process is mainly used to produce galvanized steel sheets, that is, coiled steel sheets are continuously immersed in galvanized bath to produce galvanized steel sheets.
B. Galvanized steel sheet. The galvanized steel sheet produced by electroplating has good processability. However, the coating is thinner and the corrosion resistance is not as good as that of hot dip galvanized sheet.
C. Single-sided and double-sided galvanized steel sheets. One-sided galvanized steel sheet, that is, only one-sided galvanized products. It has better adaptability than double-sided galvanized sheet in welding, painting, anti-rust treatment and processing. In order to overcome the shortcomings of single-sided galvanized sheet, there is another kind of galvanized sheet coated with thin zinc on the other side, that is, double-sided difference galvanized sheet.
