product description

what?

GL steel coil ASTM A792 provides good protection by covering the surface of steel with an alloy of aluminium and zinc, which forms a dense quaternary crystal.A792 Aluminium Zinc Plated Steel Sheet is usually used in application scenarios that require a high level of corrosion resistance, such as buildings, bridges, vehicles and so on.

Compositio

The alloy composition of GLC ASTM A792 mainly consists of 55% Aluminium, 43.4% Zinc and 1.6% Silicon, which solidify at a high temperature of 600°C to form a quaternary crystalline structure of Aluminium - Iron - Silicon - Zinc.
This structure not only provides good corrosion resistance, but also effectively prevents rust and corrosion of the steel sheet, thus extending its service life.
In addition, the production method of galvalume steel coil ASTM A792 includes cold rolling, which is suitable for making plates of high quality carbon structural steel, the thickness of which can be thin.

The ASTM A792M standard was developed specifically for aluminium zinc plated steel sheets, where ASTM stands for American Society for Testing and Materials and M stands for Material Standard.The A792M standard details the chemical composition, mechanical properties, dimensions, and other requirements for aluminium zinc plated steel sheets, ensuring the quality and performance of the steel sheets.

Corrosion resistance

A792 aluminised zinc has good corrosion resistance due to the ability of zinc and aluminium to form a protective coating in air. Zinc is chemically active and can form a thin but dense film of alkaline zinc carbonate in air at room temperature, which prevents further oxidation. Aluminium, on the other hand, can form an insoluble oxide layer in the air, which serves as a barrier to protect the substrate from corrosion.

Heat Resistance

A792 galvalume plate is stable at temperatures of up to 315 degrees Celsius, a characteristic that makes it suitable for a wide range of applications where high temperature resistance is required.

High reflectivity

A792 zinc aluminide is highly reflective and, in particular, almost twice as thermally reflective as galvanised steel, which makes it a significant energy saver when used, for example, in steel-framed metal roofs.

Ease of painting

A792 zinc aluminide has excellent adhesion to paint, which means that it can be painted without pre-treatment or weathering, simplifying the application process.

Summary

These features make A792 aluminised zinc sheet have a wide range of applications in construction, automotive and household appliances, especially in environments where corrosion resistance, high temperature resistance, high reflectivity and ease of painting are required, A792 aluminised zinc sheet demonstrates its unique advantages and value.

APPLICATIONS

A792 galvalume steel coil is mainly used in various automobiles, high- and low-voltage switchgear cabinets, and mechanical equipment parts. In addition, A792 galvalume sheets have high strength and good formability, which can meet the processing needs of various complex structures. In the automotive industry, it is widely used in the production of internal and external coverings and structural parts, while in the field of machinery and equipment, it is used to make a variety of fittings to improve the durability and reliability of the equipment.
