Galvanized Steel Coils
Galvanized coil, the thin steel sheet is immersed in a molten zinc tank to make a layer of zinc thin steel sheet adhered to its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel sheet is continuously immersed in a plating tank with molten zinc to make a galvanized steel sheet; Alloy galvanized steel sheet. This steel sheet is also made by hot dip method, but after leaving the tank, it is immediately heated to about 500℃ to form an alloy film of zinc and iron. This galvanized coil has good coating adhesion and weldability.

Product Description

Galvanized coil, the thin steel sheet is immersed in a molten zinc tank to make a layer of zinc thin steel sheet adhered to its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel sheet is continuously immersed in a plating tank with molten zinc to make a galvanized steel sheet; Alloy galvanized steel sheet. This steel sheet is also made by hot dip method, but after leaving the tank, it is immediately heated to about 500℃ to form an alloy film of zinc and iron. This galvanized coil has good coating adhesion and weldability.

Full cold galvanizing process:

Chemical degreasing → hot water washing → water washing → electrolytic degreasing → water washing → acid washing → rust removal → water washing → electrogalvanizing process → water washing → passivation → hot water washing → drying → quality inspection → packaging and sales

Scope Of Application

Building Materials Field

Electrogalvanizing has a wide range of applications in the field of building materials. First of all, electro-galvanizing can be used to manufacture construction steel, which not only prevents metal oxidation and prolongs its service life, but also enhances the toughness, strength and corrosion resistance of steel, and improves the performance of steel. Secondly, in the decoration of building exterior walls, electro-galvanized aluminum alloy, electro-galvanized iron alloy and other materials are also widely used, which can protect the steel structure and prevent oxidation, but also has the characteristics of beauty and fire prevention.

Automobile Manufacturing Field

Electrogalvanizing is also a commonly used material in the field of automobile manufacturing. Electro-galvanized coating can be used for surface protection and repair of automobile parts to avoid oxidation corrosion and damage, and to improve the service life of automobiles. The electro-galvanized coating can also be used in the manufacture of parts such as car frames and casings to avoid oxidation and corrosion, and improve the overall quality and durability of the car.

Home Appliance Manufacturing Field

In the field of home appliance manufacturing, galvanizing also has its important applications. For example, the manufacture of refrigerators, washing machines and other household appliances shell, lining, refrigerator and other parts, usually need to use electro-galvanized material for surface coating, to prevent metal oxidation, improve appearance and performance.
