Aluminum-Zinc Coated Steel

Product Details: Galvalume Steel Coil

Overview:

Galvalume Steel Coil, produced by Dufusteel, utilizes cold-rolled steel sheets as a substrate, solidified with a composition of 55% aluminum, 43.4% zinc, and 1.6% silicon at 600°C. This combination provides enhanced corrosion resistance and durability, combining the physical protection of aluminum with the electrochemical protection of zinc.
