ASTM A792 Galvalume Roof Panels AZ30 - AZ150 High Corrosion Resistance
ASTM A792 Galvalume steel coils Roofing sheet material
| What is Galvalume Steel? |
Galvalume steel is carbon steel coated with an alloy that combines the impervious properties of aluminum with the malleability and galvanic protection of zinc. The alloy coating gives galvalume steel coil and sheets a smooth, plain finish.
Galvalume steel is carbon steel coated with an aluminum-zinc alloy using a continuous hot-dip process, combining the corrosion protection and high-temperature resistance of aluminum with the formability and galvanic protection of zinc.
The galvalume coating is an alloy consisting of approximately 55% aluminum, 43.4% zinc and 1.5% silicon by weight, which is applied to steel by the continuous hot dip process. Galvalume steel sheet offers the best qualities of aluminum coated (aluminized) and zinc coated steel sheet (galvanized). The aluminum/zinc coating has barrier corrosion resistance and heat resistance similar to aluminum coated steel. It also has good bare edge galvanic protection and forming qualities similar to continuously annealed commercial quality galvanized. The appearance of Galvalume coating is quite distinctive. Its smooth, flat and fine spangle and a silvery metallic appearance make it attractive in unpainted applications.
Galvalume Steel Coil is an ideal roofing material because of its strength, extraordinary outdoor corrosion resistance and longevity. Galvalume is offered in both bare and pre-painted versions.
Benefits of Galvalume Steel
- Handles the heat: Performs well above 300 °C
- Protects against corrosion: An aluminum layer shields the steel’s interior
- Easy to paint: Galvalume steel offers the perfect adhesiveness to make your finish attractive
