G550 Galvalume Steel

G550 Galvalume Steel is an innovative metallic material that perfectly combines the structural strength of G550 steel with the superior corrosion resistance of its aluminum-zinc coating (55% aluminum, 43.4% zinc, and 1.6% silicon), making it ideal for modern construction and industrial applications.

Our G550 Galvalume Steel uses high-quality raw materials and advanced coating technology, exhibiting stable performance and aesthetics even in harsh environments.

Reasons to Choose G550 Aluminum-Zinc Coated Steel

• Superior Structural Strength: High yield strength enables a 15-30% reduction in material usage compared to other materials under identical load requirements.
• Exceptional Corrosion Resistance: Both aluminum and zinc in the surface coating provide corrosion protection. The aluminum element forms a dense oxide layer, delivering corrosion resistance several times greater than GI steel at equivalent coating thicknesses.
• High-Temperature Resistance & Thermal Reflectivity: The aluminum-zinc coating exhibits excellent heat resistance and reflects up to 80% of solar heat, making it ideal for high-temperature environments and roofing systems.
• Superior Formability: G550 steel offers excellent flexibility and formability, supporting diverse processing techniques including stamping, shearing, bending, and deep drawing. As a substrate for PPGL steel coils, it ensures strong paint adhesion.
