Coated(Optional)
Galvalume Steel Coils can have a fingerprint-resistant coating applied to their surface, which not only prevents fingerprints from being left during handling, manufacturing and installation, but also effectively protects the steel from oxidation and rusting.
This sheet cannot be painted and can only be used bare. The fingerprint-resistant coating comes in various colors, mostly green and blue, and can also be colorless.

Why Choose Our Galvalume Steel Coils?
✅ Outstanding Corrosion Resistance
Bomis Steel Galvalume steel coils feature a 55% aluminum, 43.5% zinc, and 1.5% silicon alloy coating (AZ30–AZ275), offering up to four times the corrosion resistance of standard galvanized steel.
✅ Superior Heat Reflectivity
The aluminum-rich surface reflects heat and UV rays, making Galvalume ideal for roofing and cladding in high-temperature or sunny environments.
✅ Clean Surface & Long-Lasting Appearance
With a smooth, uniform spangle finish, Galvalume provides a modern, metallic look that stays clean and visually appealing over time.
✅ Excellent Formability & Edge Protection
Galvalume coils are easy to form, cut, and weld. The coating resists edge corrosion with a natural self-healing effect, extending the product’s lifespan.
