Wholesale DX51 China Steel Factory Hot Dipped Galvanized Steel Coil Manufacturer and Supplier

DX51 China Steel Factory Hot Dipped Galvanized Steel Coil

Short Description:

For galvanized coils, the sheet steel is immersed in a molten zinc bath to make a sheet of zinc coated on its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in a plating tank with zinc melted to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also manufactured by hot dip method, but immediately after being out of the tank, it is heated to about 500 ℃ to form an alloy coating of zinc and iron. This galvanized coil has good paint adhesion and weldability.

Product Detail

Galvanized coil, a thin steel sheet that is dipped into the molten zinc bath to make its surface adhere to a layer of zinc. At present, it is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously dipped in the bath with melted zinc to make galvanized steel plate; Alloyed galvanized steel sheet. This kind of steel plate is also made by hot dip method, but it is heated to about 500 ℃ immediately after being out of the tank, so that it can form an alloy coating of zinc and iron. This galvanized coil has good coating tightness and weldability. Galvanized coils can be divided into hot-rolled galvanized coils and cold-rolled hot-rolled galvanized coils, which are mainly used in construction, household appliances, automobiles, containers, transportation and household industries. In particular, steel structure construction, automobile manufacturing, steel warehouse manufacturing and other industries. The demand of construction industry and light industry is the main market of galvanized coil, which accounts for about 30% of the demand of galvanized sheet.

Main Application

Features

1. Corrosion Resistance: Cold Rolled Carbon Steel Coil is an economical and effective rust prevention method that is often used. About half of the world's zinc production is used for this process. Zinc not only forms a dense protective layer on steel surface, but also has cathodic protection effect. When the zinc coating is damaged, it can still prevent the corrosion of iron based materials through cathodic protection.

2. Good Cold Bending and Welding Performance: low carbon steel is mainly used, which requires good cold bending, welding performance and certain stamping performance

3. Reflectivity: high reflectivity, making it a thermal barrier

4. The Coating Has Strong Toughness, and the zinc coating forms a special metallurgical structure, which can withstand mechanical damage during transportation and use.

Application

Cold Rolled Galvanized Steel Coil products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery, commerce and other industries. The construction industry is mainly used to manufacture anti-corrosion roof panels and roof gratings for industrial and civil buildings; In light industry, it is used to manufacture household appliance shells, civil chimneys, kitchen appliances, etc. In automobile industry, it is mainly used to manufacture corrosion resistant parts of cars, etc; Agriculture, animal husbandry and fishery are mainly used as food storage and transportation, frozen processing tools for meat and aquatic products, etc; It is mainly used for the storage and transportation of materials and packaging tools.
