According to the methods of production and processing, the following categories can be divided into the following categories:
(1) hot dip galvanized sheet. The thin steel sheet is immersed in the molten zinc bath to make the surface adhere to a thin sheet of zinc. At present, the continuous galvanizing process is mainly used to produce the galvanized steel sheet continuously immersed in the zinc plating bath.
(2) alloying galvanized steel sheet. The steel plate is also made by hot dipping, but after it is discharged, it is heated to about 500 degrees Celsius to make the alloy coating of zinc and iron. This galvanized sheet has good coating adhesion and weldability.
(3) galvanized steel plate. The galvanized steel sheet produced by electroplating has good workability. But the coating is thinner and the corrosion resistance is not as good as that of hot dip galvanized steel sheet.
(4) single side plating and double-sided differential galvanized steel sheet. Single sided galvanized steel, that is, only one galvanized product. It has better adaptability than double sided galvanized sheet in welding, painting, rust prevention and processing. In order to overcome the shortcomings of uncoated zinc on one side, there is a galvanized sheet coated with thin zinc on the other side, that is, double-sided galvanized sheet.
5. Alloy and composite galvanized steel sheet. It is made of zinc and other metals, such as lead and zinc, and even composite plated steel plates. This steel plate has excellent rust resistance and good coating properties.
In addition to the above five, there are also coloured galvanized steel sheets, printed zinc coated steel sheets and PVC laminated galvanized steel sheets. But the most commonly used hot-dip galvanizing plate is still in common use at present.
