Coil Galvalume
Outstanding Corrosion Resistance: The aluminum-zinc-silicon alloy coating ensures long-lasting protection against rust, oxidation, and harsh weather conditions.
High Heat & Oxidation Resistance: Maintains stability and surface integrity even under high-temperature environments.
Lightweight with High Strength: Delivers excellent mechanical performance with thinner gauges, reducing material weight and overall project cost.
Excellent Formability & Surface Quality: Smooth, uniform surface with strong coating adhesion, making it ideal for bending, cutting, painting, and other fabrication processes.
Hot-Dipped Galvalume Steel Sheet (GL Steel Sheet)
Our hot-dipped galvalume steel sheet—also known as GL steel sheet—is manufactured with a premium aluminum-zinc-silicon alloy coating (55% Aluminum, 43.5% Zinc, 1.5% Silicon). This advanced surface treatment provides outstanding corrosion resistance, heat resistance, and oxidation resistance, making it an ideal choice for construction, household, and industrial applications.

Features
Superior Corrosion Resistance – The aluminum-zinc coating ensures long-lasting protection against rust and oxidation.
High Heat Resistance – Retains strength and coating adhesion under high-temperature environments.
Excellent Surface Quality – Smooth, bright surface finish with strong coating adhesion for further painting or lamination.
Lightweight & Strong – Enables thinner gauges while maintaining high tensile strength, reducing weight and cost.
Good Formability & Workability – Ideal for bending, cutting, and shaping without compromising coating integrity.
Structure
The galvalume steel sheet structure is engineered through a hot-dipping process, forming a uniform alloy layer of aluminum-zinc-silicon that tightly bonds with the steel substrate. This structure provides:
Barrier Protection: Aluminum forms a physical shield against external elements.
Galvanic Protection: Zinc sacrifices itself to prevent steel corrosion.
Enhanced Durability: The Si component strengthens adhesion between alloy coating and steel sheet.
Applications
Thanks to its unique combination of strength, durability, and corrosion resistance, hot-dipped galvalume steel sheets are widely applied in:
Construction Industry
Roofing sheets, wall cladding, and building facades
Pre-engineered steel buildings (PEB) and structural frames
Household Appliances
Refrigerators, washing machines, and microwave ovens
Automotive & Transportation
Car panels, underbody parts, and truck bodies
Agriculture & Industrial Equipment
Grain silos, barns, ventilation systems, and industrial enclosures
