  • Why UniCote®

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.

The extra benefits of UniCote® Coastal

Inspiring building design and architectural
creativity, with a choice in style and performance.
