Galvalume Trapezoidal
Superior Corrosion & Weather Resistance: The Al-Zn alloy coating provides excellent protection against atmospheric corrosion, heat, and oxidation, ensuring long service life even in harsh outdoor environments.
High Strength with Lightweight Performance: At the same strength level, sheets can be made thinner and lighter, reducing structural load while lowering material and construction costs.
Excellent Formability & Processing Performance: Smooth surface and stable coating adhesion make the material easy to bend, cut, shape, and install—ideal for roofing, siding, and complex fabrication.
Hot-dipped galvalume steel sheet, commonly referred to as GL steel sheet, is a steel plate coated with an alloy of aluminum (55%), zinc (43.5%), and silicon (1.5%) through a hot-dipping process. It features a smooth surface, outstanding resistance to atmospheric corrosion, heat, and oxidation, along with excellent coating properties and superior workability.
