Galvalume sheet
Galvalume sheet
Our Bare Galvalume Roofing Sheet are available in numerous sizes, designs and colors and are in extensively demanded in homes, restaurants, hotels and many other places. Further our quality auditors test this sheet on set parameters to ensure a flawless product from our end and retain customer’s permantantly. Our products are of rugged design, excellent strength, durable and easy to install. The combination of zinc and aluminum in Galvalume which enhances both the positive and negative effects of aluminum. Galvalume has barrier corrosion resistance and heat resistance similar to aluminized material and good bare edge galvanic protection and forming qualities like galvanized material.
The alloy-coated product contains 55% aluminum, 43.5% zinc and 1.5% silicon by weight. Applied by the traditional hot-dipping process, Galvalume is perfect for applications that call for high corrosion resistance and heat reflectivity. It is typically used in construction, appliances, agricultural equipment and several non-exposed automotive components. Thanks to its shiny spangled appearance, Galvalume can be used even without a layer of paint over it. It has better resistance to oxidation and can withstand temperatures up to 315°C without discolouration.

Advantages
The application of an organic coating eliminates the need for ArcelorMittal to apply conventional chemical treatment and vanishing oil. This enhancement offers our customers and users the following benefits:
Reduced costs
- Eliminates the need for roll forming lubricants, since the product is designed to be roll formed dry
- Lower maintenance costs – reduced coating build-up and reduced tool wear will extend die life
- Improved productivity – extended die life results in longer production runs
- Enhanced scheduling flexibility – eliminates the need for die clean-up prior to roll forming prepainted product
- Reduced energy costs for building owners – the bright appearance provides excellent solar reflectivity
Storage, handling and installation benefits
- Excellent resistance to staining during transit and field storage
- Reduces smudging and streaks associated with rolling oils
- Effectively resists fingerprinting and footprinting during installation
Improved safety
- Finished product is delivered to the job site dry, providing a safer, oil-free surface for workers
