Galvalume Steel Corrugated Roof Sheet – Product Overview
Galvalume steel corrugated roof sheets are available in a variety of profiles including wavy, trapezoidal, and ribbed designs. Suitable for use as single-layer roofing, overlay on existing roofs, or as part of steel sandwich panels, these sheets offer a cost-effective alternative to traditional roofing materials.
Lightweight and easy to install, they significantly reduce labor time and costs. Their durability, low maintenance requirements, and recyclability further enhance their economic advantage. The sheets feature a smooth, bright surface with an aesthetically pleasing corrugated design. Excellent paint adhesion allows for custom color coatings, providing both visual appeal and design flexibility.
Key Features:
✅ Superior Corrosion Resistance
The aluminum component in the Galvalume coating forms a dense, self-protecting oxide layer when exposed, delaying further corrosion. This results in up to 3x better corrosion resistance than standard galvanized steel, extending service life by 2–6 times under comparable conditions.
✅ High Thermal Reflectivity
With a reflectivity coefficient twice that of conventional galvanized roofing, our sheets help reduce indoor temperatures in summer, cutting cooling costs and improving energy efficiency—ideal for warm climates.
✅ High-Temperature Resistance
Capable of withstanding temperatures over 300°C, Galvalume sheets maintain structural integrity and performance under prolonged heat exposure.
✅ Smooth & Uniform Finish
The surface is consistently smooth with an attractive silvery-spangled appearance, ready to use without additional treatment—perfect for both residential and commercial applications.
✅ Excellent Formability & Paint Adhesion
The substrate offers outstanding formability for easy cutting, punching, and shaping. It also ensures strong paint adhesion, allowing for durable and vibrant painted finishes.
