Zincalume Steel Coil and Sheet
Zinc / Aluminum alloy-coated steel or Zincalume® steel is composed of 55% aluminium, 43.5% zinc and 1.5% silicon which provides a superior coating for steel, as well as 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 Zincalume steel’s superior corrosion performance.
Comparative coating loss of galvanized and Zincalume steel at sites ranging from rural to severe marine.
Extensive research has proven that Zincalume 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 Zincalume steel is still in good condition, while the roof made from galvanized steel shows significant red rust.
ZINCALUME steel has been used with striking effect by leading architects to create the latest in modern building designs, through to classic roofing styles and rural sheds.
Unique aluminium/ zinc/ magnesium alloy coating which acts in three ways:
1. Magnesium, aluminium and zinc compounds are strategically positioned in the coating to provide sacrificial protection
2. Magnesium compounds encourage the formation of a robust barrier, slowing the rate of subsequent corrosion
3. Magnesium compounds also activates the metal coating.
