ZINCALUME® steel

Jump to content Products | Projects | Articles

ZINCALUME® steel has been used with striking effect by leading architects to create the latest in modern building designs, though to classic roofing styles and rural sheds.

BlueScope’s ZINCALUME® steel with Activate® technology has a unique aluminium/ zinc/ magnesium alloy coating (AM) which acts in three ways:

  • Magnesium, aluminium and zinc compounds are strategically positioned in the coating to provide sacrificial protection
  • Magnesium compounds encourage the formation of a robust barrier, slowing the rate of subsequent corrosion
  • Magnesium compounds also ‘activate’ the metal coating.

The result is a tough protective coating that provides enhanced corrosion resistance.
