The surface coating of our galvalume steel is a unique honeycomb structure, the "honeycomb" consisting of zinc-containing aluminum. This combination provides anodic protection, but as the zinc content decreases and the zinc material is wrapped in aluminum, electrolysis becomes less likely. However, this means that when the galvanized sheet is cut, the cut edge loses its protection, making it prone to rust. To solve this problem, we recommend using paint or zinc-rich paint to protect the edges and prolong the life of the panels.
Surface treatment: Chemical treatment, oil, dry, Chemical treatment and oil, anti-finger print.

Our galvalume steel boasts an impressive array of properties, making it the ultimate choice for all your roofing projects. Not only is it formable, weldable and paintable, but it also offers excellent corrosion resistance even under the harshest atmospheric conditions. This is achieved through the combination of zinc's sacrificial protection and aluminum's barrier protection, ensuring your roof will remain strong and resilient for years to come.
Compared to conventional hot-dip galvanized steel, our galvalume steel coatings perform 2 to 6 times better than galvanized coatings. This means you can rest easy knowing your roof is well protected from rust and deterioration. Additionally, galvalume steel is available in a variety of gauges, allowing you to choose the perfect size and thickness for your specific project requirements.
Our galvalume steel is versatile and can be used in a wide range of applications beyond roofing. From siding and cladding to automotive components and appliances, you can rely on our galvanized steel to deliver superior performance and longevity.
