STS42 Galvanized Steel Sheet Plate Metal Customized Size GB/T3880

      Galvanized sheet is a steel plate with a layer of zinc on the surface. Galvanizing is an economical and effective method which is often used to prevent rust.
      According to production and processing methods, it can be divided into the following categories:
① Hot-dip galvanized steel sheet. A thin sheet of steel is immersed in a molten zinc tank so that the surface is adhered to a thin sheet of zinc. At present, continuous galvanizing process is mainly used in the production, that is, the rolling steel plate is continuously immersed in the melting zinc plating tank made of galvanized steel plate;
② Alloyed galvanized steel sheet. This steel plate is also made by hot dipping, but immediately after it is taken out of the tank, it is heated to about 500℃ to form a thin alloy film of zinc and iron. This galvanized sheet has good coating tightness and weldability;
③ Galvanized steel sheet. This galvanized steel plate made by electroplating has good workability. But the coating is thinner, corrosion resistance is not as hot dip galvanized sheet;

      Packing:It is divided into two kinds of galvanized sheet and galvanized sheet packaging with coil length. Generally, it is packed in iron sheet, lined with moisture-proof paper, and bound on the bracket with iron kidneys. The binding should be firm to prevent the inner galvanized sheet from rubbing against each other.
