Product Introduction
Galvalume Steel Coil (GL Coil) is a high-performance coated steel product with an aluminum-zinc alloy coating, combining the corrosion resistance of zinc with the heat resistance and durability of aluminum. The standard coating composition typically contains 55% aluminum, 43.4% zinc, and 1.6% silicon, providing superior protection compared with traditional galvanized steel in many environments. Queen Metal supplies Galvalume coils with excellent corrosion resistance, heat resistance, surface appearance, and long service life for construction, automotive, solar, and industrial applications. Available in different steel grades, thicknesses, widths, coating weights, and surface finishes. Customized specifications and processing services are available according to customer requirements.
