Product Specification

AZ150 AFP Galvalume Steel Aluzinc Steel Coil

0.42BMT G550 Corrugated Sheet Panels Roof Tiles Structural Steel ASTM A792M

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

• Strong Corrosion Resistance: It provides corrosion resistance three times stronger than pure galvanizing. The surface features attractive zinc flowers and is suitable for use as exterior panels on building roofs.
• Long-term Color Stability: Designated as AZ150, aluminum-zinc-plated steel plates maintain their color over extended periods, resisting chemical corrosion. When exposed, a physical reaction occurs, forming a protective aluminum oxide film on the surface. This film isolates the steel from external chemicals, preventing rust and preserving the integrity of the material.
• Mechanism of Corrosion Resistance: Aluminum primarily contributes to its robust corrosion resistance. In the event of zinc abrasion, aluminum reacts to form a dense layer of aluminum oxide, effectively preventing further corrosion of the underlying steel.

These properties make aluminum-zinc-plated light steel a durable and protective choice for various applications, particularly where corrosion resistance and aesthetic appeal are crucial.

Popularity of Aluzinc Steel Coils (Galvalume Steel Coils) in the Brazilian Market
