Introduction to Galvalume Steel Strip
Galvalume Steel Strip is a type of steel strip that is coated with an aluminum-zinc alloy. The composition of the alloy is 55% aluminum, 43.4% zinc and 1.6% silicon, and it is solidified at a temperature of around 600 °C. This alloy coating gives the Galvalume Steel Strip superior performance compared to other types of steel.
Better Performance and Corrosion Resistance
One of the key advantages of Galvalume Steel Strip is its improved performance. The aluminum-zinc alloy coating helps to increase the strength of the steel, making it more durable and long-lasting. Additionally, the corrosion resistance of Galvalume Steel Strip is 2-6 times better than hot dip galvanized steel. This makes it an ideal choice for use in environments where rust and corrosion are potential issues.
Conclusion
In summary, Galvalume Steel Strip is a highly-effective and versatile steel product that can provide superior corrosion resistance and improved performance compared to other types of steel. As a result, it is a popular choice for use in a wide range of industrial and construction applications.

Galvalume steel, also known as aluminum-zinc coated steel, is widely used in various industries due to its excellent corrosion resistance, heat resistance, and reflective properties.
Construction industry: Metal sheets used to make roofs and walls, with good weather resistance and appearance decoration.
Automobile manufacturing industry: Manufacture of car body shells and parts to provide a certain strength and rust resistance.
Home appliance industry: Production of shells for appliances such as refrigerators, washing machines, air conditioners, etc., to protect internal parts and give a beautiful appearance.
1. Q: When should Galvalume not be used?
A: Galvalume should not be used on, in, or around concrete or mortar. Concrete and mortar are highly alkaline environments. Bare Galvalume and painted Galvalume sheets suffer rapid corrosion when in contact with mortar and concrete. Bare Galvanized and painted Galvanized perform better in this type of environment.
2.Q: Why does Galvalume turn black?
A: The dark stains that are at times visible on galvannealed sheet are caused by the same wet storage conditions that cause white rust on galvanized surfaces. Since galvannealed sheet is often shipped “dry, no oil, no surface passivation”, it is very important to control the shipping and storage of this product.
3. Q: Is Galvalume shiny?
A: Galvanized steel has a shiny silver finish, while Galvalume has a matte gray finish. This difference in appearance is due to the composition of the coating. The aluminum and silicon in the Galvalume coating give it a duller appearance. When it comes to cost, Galvanized steel is generally cheaper than Galvalume.
