1. Excellent corrosion resistance.

Like galvanized steel, the Al-Zn coating protects the base metal. In particular, as the zinc layer wears away, a dense alumina layer is left to prevent further corrosion of the base metal. GL steel has been proven to last 3 times longer than GI steel. This is why GL steel is preferred in harsh environments.

2. High temperature resistance.

Aluzinc steel has good heat resistance, can withstand temperatures over 300 degrees Celsius, and is often used in chimneys, oven lights, and lampshades.

3. High reflectivity.

The thermal reflection coefficient GL is twice that of galvanized steel, so it is often used as a thermal insulation material. Therefore, it is the best choice for roofing in hot climates.

4. Beautiful appearance

The surface of GL steel is smooth and shiny, giving it a beautiful appearance. So it can be used directly without painting.
