Aluzinc Roofing Sheet

 

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.

Features of Aluzinc Roofing Sheet

 

  • Excellent corrosion resistance: The Galvalume layer is 2~5 times that of ordinary galvanized steel (GI), especially in acidic and salt spray environments. The zinc component can sacrifice the anode to protect the steel base when the coating is scratched.
  • Ultra-long life: Under standard conditions (non-extreme corrosive climates), the service life can reach 20~30 years, far exceeding galvanized sheet (10~15 years).
  • High temperature and heat resistance: The aluminum component can reflect about 80% of solar radiation heat, reduce the roof temperature, and can withstand high temperatures of 315°C for a long time (up to 700°C in the short term).
