What is GALVALUME? I galvalume steel coil manufacturers

Updated on: 27/03/2020

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.
