GL 0.43*1200MM AZM150 ASTM A792M CS-B AFP Galvalume Steel Corrugated Sheet Panels Roof Tiles GL 55% Aluzinc Steel Coil

The surface of the Galvalume / Aluzinc steel sheet presents a unique smooth, flat, and gorgeous spangle looking, with a silver white base color. The special coating structure gives it excellent corrosion resistance. The normal service life of Galvalume / Aluzinc Steel Sheet and Coils can reach 25 years, and they have good heat resistance and can be used in high-temperature environments at 315 ℃; The adhesion between the coating and the paint film is good, and it has good processing performance, which can be used for stamping, shearing, welding, etc; The surface conductivity is very good.

The coating consists of 55% aluminum, 43.5% zinc, and 1.5% silicon in weight ratio, respectively. The production process of aluminum zinc steel sheet is similar to that of galvanized steel plate and aluminum plated plate, and it is a continuous melting coating process. 55% aluminum zinc alloy coated aluminum zinc steel plate has superior corrosion resistance compared to galvanized steel plate of the same thickness when exposed to the same environment on both sides. 55% aluminum zinc alloy coated aluminum zinc steel ( 55% Alu-zinc Steel) plate not only has good corrosion resistance, but also color coated products have excellent adhesion and flexibility.

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.
