Aluzinc Steel Coil and Sheet
Zinc / Aluminum alloy-coated steel or Aluzinc steel is composed of 55% aluminium, 43.5% zinc and 1.5% silicon which provides a superior coating for steel, also better corrosion resistance.
As aluminium in the coating provides barrier protection to the steel whilst the zinc component provides sacrificial cut edge protection. Therefore, This double protection mechanism is the secret behind Aluzinc steel’s superior corrosion performance.
Comparative coating loss of galvanized and Aluzinc steel at sites ranging from rural to severe marine.
Extensive research has proven that Aluzinc performed the desired non-corrosive functions far better than Galvanized steel. Actual field testing after 20 years has also shown that the roof made from Aluzinc steel is still in good condition, while the roof made from galvanized steel shows significant red rust.
