Galvalume Steel Coil is a high-performance steel product coated with an alloy of 55% aluminum, 43.4% zinc, and 1.6% silicon.
Galvalume Steel Coil is a high-performance steel product coated with an alloy of 55% aluminum, 43.4% zinc, and 1.6% silicon. This unique coating combines the corrosion resistance of aluminum with the galvanic protection of zinc, providing outstanding durability and heat reflectivity.
The key advantages of
Galvalume steel coil include three to six times the corrosion resistance of regular galvanized steel, excellent heat and oxidation resistance, and long-term surface stability. Even when exposed to harsh outdoor environments, the aluminum-zinc coating forms a tightly bonded protective layer that prevents rust and extends service life.
In the construction industry,
Galvalume steel coils are widely used for roofing, wall panels, ceiling systems, and building structures, providing both strength and modern appearance.
In the automotive sector, they are applied in exhaust systems, underbody panels, and heat shields, where resistance to high temperatures and corrosion is essential.
In the appliance industry,
Galvalume steel coils are used in refrigerator backs, washing machine panels, and air-conditioning units, offering both aesthetic appeal and reliable protection.
In the energy and agricultural sectors, they are used for solar panel frames, grain silos, and greenhouse structures, taking advantage of their high reflectivity and weather resistance.
Another major benefit is energy efficiency — the aluminum-rich coating reflects heat and sunlight, helping reduce cooling costs in buildings and improving energy performance. Additionally, Galvalume steel is 100% recyclable, supporting sustainable industrial practices.
