Galvalume Steel Coil

Wanzhi Group produces and sells high-quality Galvalume steel coil, sheet, roofing, etc. The zinc-aluminum alloy layer of GL steel protects the steel, effectively prevents rusting, and improves heat resistance and heat reflectivity. It is widely used in outdoor construction projects in hot and humid areas.

Galvalume Steel Coil Processing

Galvalume steel coils, also known as Aluzinc steel coils, are made of cold rolled or hot rolled sheet with an aluminum-zinc alloy layer containing 55% aluminium, 43% zinc, and 2% silicon, which is lighter in weight and more resistant to corrosion than galvanized steel. GL coil is available as raw material for stamping, bending, GL steel flat sheets, GL steel roofing sheets, GL steel panels, etc.

GL Steel Coil Products

Corrugated Steel – GL
Galvalume Roofing
GL steel flat sheets: GL coil cut to length with a flat and smooth surface.
Galvalume roofing: GL sheet is a raw material and is available in different surface configurations to improve structural strength.
Galvalume corrugated: GL sheet is stamped and molded into corrugated shapes for rigidity and compression resistance.
PPGL sheet: GL coil coated with organic coatings, which are colorful and decorative.

Galvalume Steel Coil Specifications

Galvalume Steel Coil relies on a layer of aluminum-zinc alloy that prevents the steel from rusting by isolating it from air and other substances. The thickness of the alloy layer determines the environment and service life. Wanzhi Group offers GL steel in thicknesses from AZ20 – AZ350g. Dimensions, surface structure, and surface treatment can be customized.
