Galvalume Steel Corrugated Sheets: A Cost-Effective & Durable Roofing Solution

Galvalume steel corrugated sheets are versatile roofing and cladding materials available in wavy, trapezoidal, or ribbed designs. 

They can be used as:

Single-layer roofing

Overlay for existing roofs

Core material in steel sandwich panels

Compared to traditional roofing materials, Galvalume sheets offer superior cost-effectiveness, lightweight ease of installation, durability, recyclability, and low maintenance. Their smooth, bright surface and corrugated design enhance aesthetic appeal, while their excellent paint adhesion allows for customization in various colors.

Key Advantages of Galvalume Steel

Superior Corrosion Resistance

The aluminum-zinc coating provides 3x the corrosion resistance of standard galvanized steel (GI).

When zinc erodes, the aluminum forms a protective oxide layer, preventing further rust.

Service life is 2–6 times longer than GI panels under the same conditions.

High Thermal Reflectivity

Reflects twice as much heat as galvanized steel, reducing indoor temperatures in summer and lowering cooling costs.

Ideal for hot climates.

High-Temperature Resistance

Withstands temperatures exceeding 300°C, making it suitable for long-term use in high-heat environments.

Aesthetic Appeal & Uniform Finish

Features a smooth, silvery-white surface with consistent spangling (metallic flecks).

Ready for use without additional treatment, perfect for residential and commercial applications.

Excellent Formability & Paint Adhesion

Easy to cut, punch, and shape without coating damage.

Bonds well with paints, enabling durable, colorful finishes.
