Galvanized coil classification and use:

Galvanized sheet coil product introduction:

Galvanized sheet is a galvanized sheet product produced by continuous hot-dip galvanizing process with cold-rolled steel strip as the substrate.

 Galvanized sheet products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commercial industries. Among them, the construction industry is mainly used to manufacture anti-corrosion industrial and civil building roof panels, roof grilles, etc.; the light industry industry uses it to manufacture household appliance shells, civil chimneys, kitchen utensils, etc., and the automotive industry is mainly used to manufacture corrosion-resistant parts for cars, etc. ; Agriculture, animal husbandry and fishery are mainly used for food storage and transportation, meat and aquatic products freezing processing tools, etc.;

 Galvanized coil classification and use:

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

a) 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 plates are made by continuously immersing rolled steel plates in a plating tank where zinc is melted;

b) Alloy galvanized steel sheet. This kind of steel plate is also produced by hot dip method, but immediately after it is out of the tank, it is heated to about 500 ℃ to form an alloy film of zinc and iron. This galvanized sheet has good paint adhesion and weldability;

c) 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;

d) Single-sided and double-sided differentially galvanized steel sheets. 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 of not being coated with zinc on one side, there is another galvanized sheet coated with a thin layer of zinc on the other side, that is, double-sided differential galvanized sheet;

e) Alloy, composite galvanized steel sheet. It is made of zinc and other metals such as lead and zinc to make alloys and even composite plated steel sheets. This kind of steel plate not only has excellent anti-rust performance, but also has good coating performance.
