G550 SPCC Cold Rolled Galvalume Steel Sheet Galvanized Steel Sheet

Galvanized steel plate is coated with a layer of metal zinc on the surface of the steel plate to prevent corrosion on the surface of the steel plate and prolong its service life. This kind of galvanized steel plate is called galvanized steel plate.
Surface condition: Due to the different treatment methods in the coating process, the surface condition of the galvanized sheet is also different, such as ordinary spangle, fine spangle, flat spangle, no spangle and phosphating surface. German standards also specify surface grades.
The galvanized sheet should have a good appearance and should not have defects that are harmful to the use of the product, such as no plating, holes, cracks and scum, over-plating thickness, scratches, chromic acid dirt, white rust, etc. Foreign standards are not very clear about specific appearance defects. Some specific defects should be listed in the contract when ordering.

Classification

According to production and processing methods, it can be divided into the following categories:

1.Hot dip galvanized steel sheet. The sheet steel is immersed in a molten zinc bath, and a sheet of zinc is adhered to its surface. At present, it is mainly produced by continuous galvanizing process, that is, galvanized steel plate is made by continuously immersing the rolled steel plate in a plating tank where zinc is melted;

2.Alloyed galvanized steel sheet. This kind of steel plate is also made by hot-dip method, but after it is out of the tank, it is heated to about 500 ºC immediately to form an alloy film of zinc and iron. This galvanized sheet has good paint adhesion and weldability;

3. Electro-galvanized steel sheet. The galvanized steel sheet produced by the electroplating method has good workability. However, the coating is thin, and the corrosion resistance is not as good as that of the hot-dip galvanized sheet;

4.Single-sided and double-sided differential galvanized steel. Single-sided galvanized steel sheet, that is, a product that is galvanized on only one side. In welding, painting, anti-rust treatment, processing, etc., it has better adaptability than double-sided galvanized sheet. In order to overcome the disadvantage that one side is not coated with zinc, there is another galvanized sheet coated with a thin layer of zinc on the other side, that is, double-sided differential galvanized sheet;

5.Alloy and composite galvanized steel sheet. It is made of zinc and other metals such as aluminum, lead, zinc, etc. to make alloys or even composite plated steel plates. This kind of steel plate has both excellent anti-rust performance and good coating performance;

In addition to the above five types, there are also colored galvanized steel sheets, printed and painted galvanized steel sheets, and PVC laminated galvanized steel sheets. But the most commonly used is still hot-dip galvanized sheet.
