According to the production and processing methods, the aluminum profile coated galvanized sheet can be divided into the following categories:
1. Single-sided and double-sided differential galvanized steel
The coated steel sheet is a single-sided galvanized steel sheet, that is, a product that is only galvanized on one side. In welding, painting, 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;
2. Hot dip galvanized steel sheet
The sheet steel is immersed in a molten zinc bath, so that the surface of the sheet is adhered with a layer of zinc. At present, the continuous galvanizing process is mainly used for production, that is, galvanized steel plates are made by successively immersing coiled steel plates in a plating tank with molten zinc;
3. Electro-galvanized steel sheet
This galvanized steel sheet produced by electroplating has excellent workability. However, the coating is thin and the corrosiveness is not as good as that of the hot-dip galvanized sheet;
What are the varieties of galvanized sheet processed by aluminum profile coating?
4. Alloy 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 ℃ immediately to form an alloy film of zinc and iron. This galvanized sheet has excellent paint adhesion and weldability;
5. Alloy, 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 the rust function and the outstanding coating function;
In addition to the above five types of coated steel sheets, there are also colorful galvanized steel sheets, printed and painted galvanized steel sheets, and PVC laminated galvanized steel sheets. But now the most commonly used hot-dip galvanized sheet is still.
