940mm Full Hard Aluzinc AZ150 G550/SGC570 Structural Steel Corrugated Galvalume Steel Roofing Sheet

Aluminium-zinc-steel plated light steel has quite a few excellent characteristics:

Aluminum-zinc steel plated light steel possesses several outstanding characteristics:

• Superior Corrosion Resistance: It offers three times the corrosion resistance of pure galvanized steel. The surface features attractive zinc flowers, making it suitable for use as exterior panels for building roofs. Labeled as AZ150, aluminum-zinc steel plates maintain their appearance without color change over time, even on bare surfaces. In cases of chemical corrosion, a physical reaction occurs, forming an aluminum protective film on the keel. This film isolates the keel from external chemical substances, protecting the core material from rust.
• Protective Function of Aluminum: The corrosion resistance is primarily due to aluminum. When the zinc layer is worn away, aluminum forms a dense layer of aluminum oxide, which prevents further corrosion of the interior.
• Proven Durability: Aluminum-zinc plated alloy steel coils have undergone over 20 years of outdoor exposure tests in various atmospheric environments. These tests confirm that aluminum-zinc plated steel sheets offer superior protection for cut edges compared to galvanized steel sheets.
• Thermal Reflectivity: Aluminum-zinc plated mild steel has a high thermal reflectivity, twice that of galvanized mild steel, making it an excellent thermal insulator.
