INTRODUCTION OF ALUMINUM-ZINC COATED STEEL COIL

Galvalume sheet is a kind of metal sheet with excellent performance.
It is an alloy coating formed by curing aluminum, zinc and silicon at high temperature and attached to the surface of the steel sheet. Galvalume sheet has good corrosion resistance because aluminum can form a dense oxide film to prevent the erosion of external substances on the sheet.
The heat resistance of galvalume sheet is also relatively excellent and it can maintain stable performance in high-temperature environments.
In practical applications, galvalume sheets are widely used in the construction field, such as roofs, walls, etc.; in industrial manufacturing, they are also commonly used to manufacture electrical enclosures, automotive parts, etc.
For example, in buildings in some coastal areas, due to the high salt content in the air, metals are easily corroded. The corrosion resistance of galvalume sheets enables it to adapt well to this environment and extend the service life of buildings.
In automotive manufacturing, galvalume sheets can reduce the weight of the vehicle body, while having sufficient strength and corrosion resistance to improve the performance and durability of the vehicle.
Overall, galvalume sheets play an important role in many fields with their excellent performance.

The differences between aluminized zinc sheets and galvanized sheets lie in the following aspects:

1. Coating composition:
   The coating of aluminized zinc sheets mainly contains aluminum, zinc and silicon.The main component of the coating of galvanized sheets is zinc.
2. Corrosion resistance:
   The corrosion resistance of aluminized zinc sheets is usually better than that of galvanized sheets. This is because aluminum can easily form a dense oxide film in the air, which can better block external corrosive substances.
   The corrosion resistance of galvanized sheets is relatively weak, especially in harsh environments.
3. Heat resistance:
   The heat resistance of aluminized zinc sheets is better and it can maintain stable performance at higher temperatures.
   The heat resistance of galvanized sheets is relatively poor.
4. Service life:
   Generally speaking, the service life of aluminized zinc sheets is longer.
   The service life of galvanized sheets is relatively shorter.
5. Cost:
   The production cost of aluminized zinc sheets is usually higher than that of galvanized sheets, so the price is also relatively higher.
   Galvanized sheets have a lower cost and a more popular among people
   For example, in some construction projects that are exposed outdoors for a long time and have harsh environments, such as chemical plants and seaside buildings, the use of aluminized zinc sheets may be more appropriate. Although the cost is high, it can ensure the stability and safety of the building structure for a long time. For some ordinary indoor or outdoor buildings with better environments, galvanized sheets may be able to meet the requirements and provide certain protective effects while controlling the cost.
