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.
