Features

210 gms/m² magnesium coating:

  • UniCote® Coastal steel is exceptionally resistant to corrosion, particularly along cut edges, where typical steel roofs are most vulnerable. This strength comes from the addition of magnesium to the zinc/aluminium alloy. Over time, the magnesium allows the protective coating to flow over cut edges, forming a robust seal. This process initiates a sacrificial anti-corrosive reaction, providing enhanced protection and extending the lifespan of the roofing.

30% Thicker Magnesium Alloy Coating: 

  • UniCote® Coastal has a 30% thicker magnesium coating vs other industry comparable material.
  • 210 gms/m² magnesium coating
