The surface coating of galvanized steel coil has a unique honeycomb structure. Microscopically, the coating consists of aluminum "honeycombs" containing zinc. This clever design not only provides anodic protection but also reduces the chance of electrolysis due to the aluminum encapsulating the zinc material. However, it is important to note that cutting galvalume may result in a reduction in its anodic protection capabilities. Therefore, it is recommended to minimize cutting and protect the edges with anti-rust measures such as paint or zinc-rich paint to prolong the service life of the plate.
Surface treatment: Chemical treatment, oil, dry, Chemical treatment and oil, anti-finger print.

Galvalume coil is a technologically advanced multifunctional product with excellent corrosion resistance, formability, weldability and paintability. Its unique composition combines aluminium, zinc and silicon to provide a high level of rust and oxidation protection, making it the first choice for a variety of applications. Whether for construction, manufacturing or automotive use, Galvalume Coil ensures reliability and service life that exceeds industry standards and expectations. Choose Galvalume Coil for superior performance and durability.
One of the main advantages of galvalume steel is its excellent formability, weldability and paintability. This flexibility allows for easy customization and adaptation to various project requirements. In addition, due to the combination of the sacrificial protection of zinc and the barrier protection of aluminum, galvalume steel has excellent corrosion resistance under various atmospheric conditions. In fact, compared to hot-dip galvanized steel, galvalume coatings perform 2-6 times better than conventional galvanized coatings.
From a classification point of view, galvanized steel coils belong to the category of high-performance steel. It meets and exceeds the standards set by the industry, making it a reliable and trusted choice for construction, manufacturing, automotive and other demanding applications. Our galvalume coils are available in a variety of sizes to meet the specific needs of different projects, ensuring excellent performance and longevity.
