High quality Galvalume Steel Coil also known as Alu Zinc coated steel coil with superior corrosion resistance 2 to 6 times longer lifespan than GI widely used in roofing appliances and industrial panels competitive price factory direct supply.
Galvalume Steel Coil also referred to as Alu Zinc coated steel coil is an advanced coated steel material produced by a continuous hot dip process. The steel substrate is coated with an aluminum zinc alloy layer typically containing 55 percent aluminum small silicon content and zinc balance. This structure creates a highly durable barrier combining aluminum protection and zinc sacrificial performance.
Compared with traditional galvanized steel Galvalume Steel Coil offers significantly enhanced durability making it an ideal material for long term outdoor and industrial applications. The surface presents a uniform silver gray appearance with a distinctive spangle pattern suitable for both functional and decorative uses.

Superior Corrosion Resistance for Harsh Environments
Galvalume Steel Coil delivers 2 to 6 times longer service life than standard galvanized steel. It performs exceptionally well in marine industrial and high humidity environments making it a reliable choice for roofing and exterior structures.
Dual Protection Mechanism
The aluminum component forms a dense protective barrier while zinc provides electrochemical protection at cut edges and scratches ensuring long term structural integrity.
Excellent Heat Reflectivity and Energy Efficiency
Alu Zinc coated steel coil reflects heat effectively reducing building temperature and improving energy efficiency especially for roofing systems in hot climates.
Outstanding Surface Quality
Smooth bright silver finish with options including regular spangle minimized spangle and skin passed surface suitable for painting or direct use.
