Galvanized Steel Pipe
Galvanized sheet is a steel plate with a layer of zinc plated on the surface.
Galvanizing is an economical and effective anticorrosion method that is often used, and about half of the world's zinc production is used in this process.
Galvanized can generally be divided into hot dip plating or electric galvanized layer, generally widely used in construction, home appliances, vehicles and vessels, container manufacturing, electromechanical industry.

Classification Of Galvanizing:
| • Hot dip galvanized steel sheet. The sheet steel is immersed in the melted zinc tank so that the surface is adhered to a layer of zinc sheet steel. At present, it is mainly produced by continuous galvanizing process, that is, continuous immersion of rolled steel plates in melting zinc plating tanks to make galvanized steel plates |
| • Alloyed galvanized steel sheet. This steel plate is also made by hot dipping, but after the tank is out, it is immediately heated to about 500° C to generate an alloy film of zinc and iron. This galvanized sheet has good coating adhesion and weldability |
| • Electric galvanized steel sheet. The galvanized steel plate made by electroplating has good workability. However, the coating is thin and the corrosion resistance is not as good as that of hot-dip galvanized sheet. |
| • Processing and so on. In order to overcome the shortcomings of uncoated zinc on one side, there is a galvanized sheet coated with a thin layer of zinc on the other side, that is, a double-sided differential galvanized sheet. |
| • Alloy, composite galvanized steel plate. It is a steel plate made of zinc and other metals such as lead and zinc alloy or even composite plating. This steel plate not only has excellent anti-rust performance, but also has good coating performance. |
| • In addition to the above five kinds, there are color galvanized steel plate, printed coated galvanized steel plate, polyvinyl chloride laminated galvanized steel plate and so on. But the most commonly used is still hot dip galvanized sheet. |
