UniCote Coastal

For that extra protection

A steel material that heals its own cuts.

UniCote® Coastal takes our standard aluminium/zinc alloy-coated steel substrate to the next level with the addition of magnesium. This enables the zinc to ‘flow’, which seals the cut edges preventing exposure to premature corrosion. This makes it ideal for harsher environments and those nearer the coast.

Why use UniCote® Coastal?

I’m building near the water

UniCote® Coastal is suitable for projects
0 – 400m+ from marine influence:

  • ISO 9223:2012 – Category 1-4

I need corrosion resistance

UniCote® Coastal self-heals steel along the cut edges thanks to the magic of magnesium:

  • AM210 Zinc/Aluminium/Magnesium Alloy

I want a superior product

UniCote® Coastal has a 30% thicker magnesium coating vs other industry comparable material.

  • 210 gms/m² magnesium coating

It needs to be non-combustible

Suitable for Bushfire Attack Level: BAL FZ

  • Fire-rated AS1530.3
  • Conforms to AS/NZS2728:2013 / AS1397:2021

I need inspiration

UniCote® Coastal is readily available in 6 popular finishes.

Also available in 54 finishes in small order quantities and approximately 6-8 week lead time.

I want an individual design

UniCote® Coastal can be roll-formed into a variety of architectural cladding profiles and popular roofing profiles including:

  • Interlocking
  • Nailstrip
  • Snaplock
  • Standing Seam
  • Shingles/Flatlock
  • Corrugated
  • Five Rib
  • Concealed Deck
  • and more…

It needs to be a proven product

UniCote® Coastal has been used in landmark projects such as:

  • Queensland Country Bank Stadium
  • Brisbane International Cruiseship Terminal
  • NSW Royal Air Force Base
  • Queen VIC Market
  • Bondi Icebergs

How UniCote® Coastal works

The magic of magnesium.

A steel roof is most susceptible to the elements along cut edges – but not UniCote® Coastal. The addition of magnesium to the standard zinc/aluminium alloy makes all the difference. As time goes on the magnesium allows the protective metal coating to microscopically flow over the cut edge. At this point a sacrificial anti-corrosive reaction takes place and a robust seal is created.
