With over 10 years of experience in the foreign trade industry, we are proficient in international compliance and risk control. As a direct source factory, we eliminate middleman markups, offering significant price advantages through factory direct supply. We support customized production with controllable delivery cycles, providing you with cost-effective aluzinc color coated steel coil products.
Core Product Advantages
Start with the coating, because that's where roofing coils win or lose. Our color coated PPGL carries a 55% aluminum-zinc galvalume layer, and in most environments it outlasts a zinc coating of similar thickness by roughly two to four times. On a roof, that means fewer replacements and less downtime-not just a longer warranty.
Above the alloy sits a mill-applied paint system: primer plus PVDF, HDP, or SMP topcoat, baked on. You get uniform color across the whole roof, better resistance to UV fading and chalking, and a harder surface that handles transport and weather. Lighter colors also reflect more solar heat than bare galvanized, which can trim cooling costs on a metal building.
Every coil is made to ASTM A792 or JIS G3321, in AZ20 to AZ150 coating classes, and we will share mill certificates with any inquiry.


Bends, roll-forms, and stamps into tight profiles - roof panels, wall cladding, industrial parts - with no coating cracks or peeling, so it takes on complex building and fabrication work without a second thought.
It's made from 100% recyclable steel and built for the long haul: fewer repairs, fewer replacements, and lower maintenance costs year after year, which is easier to justify when budgets stretch over decades.
Sustained heat at 315°C won't deform it, and its high-reflectivity surface trims building energy use. In hot, corrosive settings where ordinary coated steel degrades fast, it keeps performing, season after season.
Application Scope
Typical jobs we supply for:
Residential roofs and villa extensions, where color and long coating life matter
Commercial buildings, shopping centers and office blocks
Factories, warehouses and logistics centers with large-span roofs
Agricultural buildings: poultry sheds, pig houses, barns and greenhouses
Coastal towns and industrial zones, where salt air and chemical exposure eat ordinary GI sheets
Retrofit and re-roofing work over existing trusses
