Zincalume®
Zinc / Aluminium alloy-coated steel or Zincalume® steel is composed of 55% aluminium, 43.5% zinc and 1.5% silicon which provides a superior corrosion coating for steel. The aluminium in the coating provides barrier protection to the steel whilst the zinc component provides sacrificial cut edge protection. This double protection mechanism is the secret behind Zincalume steel’s superior corrosion performance.
When applied to steel in appropriate conditions, it exceeds the service life of traditional zinc coatings by two times.
Zincalume® offers comparable corrosion resistant performance compared to Aluminium and Stainless Steel, in various environments.
