Aluminum Zinc Coated Steel Coil (Galvalume)
Aluminum-zinc-silicon-coated steel sheets (also known as Galvalume or aluminum-zinc alloy-coated steel sheets) use cold-rolled steel sheets as the base material. Through a hot-dip coating process, an alloy coating consisting of 55% aluminum, 43.4% zinc, and 1.6% silicon is applied to the surface of the steel sheet and cured at a high temperature of 600°C.
