difference between Aluzinc and GI roofing sheets
Alu-zinc metal roofing panels are more expensive than galvanized roofing panels and have a longer service life than galvanized steel plates. The main reason is the coating composition. The coating of galvanized steel panels only contains zinc, while galvalume steel plates contain other elements, such as silicon, in addition to aluminum and zinc, which further optimizes the performance of the steel panel. Therefore, its performance is better than that of GI steel panels.

What is an Aluzinc roofing sheet?
Aluzinc roofing sheet is a high-end roofing material with high corrosion resistance. It is made by cold rolling carbon steel plates and continuously hot-dip galvanizing on the surface. The coating content is 55% aluminum, 43.3% zinc, and 1.6% silicon. It has excellent performance, and its corrosion resistance is 2-5 times higher than that of ordinary galvanized steel plates, and it can withstand high temperatures above 300 degrees.
Aluzinc Roofing Sheet is a metal roofing sheet coated with aluminum-zinc alloy, which is made of cold-rolled steel sheet. It has the advantages of aluminum, zinc, and steel. Also known as Galvalume steel roofing sheet. It has excellent corrosion resistance, heat resistance and strength. It is widely used in building roofing wall panels, color steel substrates, automobile frames, furniture and home appliance accessories, etc. GNEE Steel stocks Aluzinc Roofing Sheets with different wave lengths, thicknesses, and substrates, and provides custom size options.
