Galvalume Steel Sheet is a high-grade anti-corrosion steel sheet, with low-carbon steel as the base and a hot-dip 55%Al-43.5%Zn-1.5%Si alloy coating on the surface. The alloy coating forms a dense protective film, offering far better corrosion and weather resistance than regular galvanized sheets, and excellent heat reflectivity. It features superior formability, stamping, and weldability for flexible fabrication, with a smooth surface, uniform coating thickness and stable room-temperature mechanical properties. Cost-effective and durable for outdoor use, it’s a mainstream anti-corrosion sheet for harsh atmospheric and outdoor working environments.
