What is GALVALUME? I galvalume steel coil manufacturers
GALVALUME® Steel is carbon steel coated with aluminum-zinc alloy by a hot-dip process. The coating composition is 55% aluminum, 43.4% zinc and 1.6% silicon. Silicon is added not to enhance the corrosion performance, but to provide good coating adhesion to the base steel substrate when the product is roll-formed, drawn, or bent during fabrication.
GALVALUME® Steel Application
GALVALUME® Steel has superior corrosion resistance more than traditional galvanized steel, so it is widely used for:
- Roofing and siding applications
- Unexposed automotive parts
- Appliances
- Furniture
- Outdoor cabinetry
- Computer cases
- Gutters
