Iron Galvanized Steel

1. Hot dip galvanized steel sheet. dip a sheet of steel into a molten zinc bath so that it adheres to a sheet of zinc. At present, the continuous galvanizing process is mainly used   for production, that is, the steel plate into a roll of continuous immersion in the melting of zinc plating tank made of galvanized steel plate;

2. Alloyed galvanized steel sheet. This steel plate is also made by hot dip, but immediately after the trough, it is heated to about 500℃, so that it generates an alloy film of zinc   and iron. This galvanized sheet has good coating tightness and weldability; This galvanized steel plate has good machinability by electroplating. But the coating is thin,   corrosion  resistance is not as good as hot dip galvanized sheet;

3. Single side plated and double side difference galvanized steel plate. Single-sided galvanized steel, that is, galvanized only on one side of the product. In welding, coating, rust   treatment, processing and other aspects, it has better adaptability than double-sided galvanized sheet. In order to overcome the shortcomings of single side not coated with   zinc, and a galvanized sheet coated with a thin layer of zinc on the other side, that is, double-sided difference galvanized sheet;

4. Alloy, composite galvanized steel plate. It is made of zinc and other metals such as lead, zinc alloy or composite plated steel plate. This kind of steel plate has excellent anti-     rust performance and good coating performance.
