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 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.
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.

GL steel can be further processed to produce a wide range of products suitable for a variety of applications, especially in industries where rust and corrosion resistance, aesthetics, and durability are high requirements.
Corrosion resistance: GL steel coil has strong corrosion resistance, which is 3 times higher than galvanized coil.
Heat Resistance: Withstands temperatures of over 300 degrees Celsius, suitable for use in high-temperature environments.
Thermal reflectivity: Aluminum-zinc alloy layers have a high degree of thermal reflectivity and can be used as an insulating material.
Physical Properties: Aluminum-zinc alloy has low density, GL steel is lightweight and high strength.
Construction: Roofing, walling, roofing components, doors and windows, etc.
Decoration: soundproof board, indoor partition, ceiling, etc.
Manufacturing: cabinets, refrigerators air conditioners, and other home appliance panels, etc.
Others: Pipes, drains, cables, fences, etc.
Wanzhi has 2 aluminized zinc production lines, which are mainly used to produce Aluzinc steel products in the range of AZ20-AZ350g. Currently, we have already supplied steel coils, steel sheets, roofing sheets, and other products to customers all over the world.
Our factory is located in Binzhou City, Shandong Province, China, with a professional team in charge of raw materials, production, quality control, and shipment, GL steel coil has obtained CE, SGS, ISO, and other certifications.
Wanzhi Group attaches great importance to steel packaging, on one hand to avoid production loss during transportation, and on the other hand to facilitate customers’ storage and sale.
Our GI, GL, PPGI, PPGL steel products have been exported all over the world, supplying products and services to nearly 100 countries. We have also customized GL steel coil, GL Roofing, etc. for different construction projects and factories.
Prepainted Galvalume Coil is based on GL steel coil and coated with one or more layers of organic coating, PE/PVDF/SMP/HDP/PVC, which retains the properties of GL steel and adds decorative features. Both are commonly used as building materials.
The price of Galvalume steel coil depends on the substrate, process, surface treatment, specification, etc. You can leave a message to tell us your requirements, we will give you a free quote according to your requirements! Besides GL steel, other steel products produced by Wanzhi Group, GI, PPGI, PPGL, ZAM, stainless steel, etc. can be customized, welcome to contact us!
