The magnesium advantage
The exposed cut edge on steel is most vulnerable to rust and corrosion. UniCote® Coastal’s magnesium-enhanced alloy helps the protective coating flow over these edges, forming a resilient barrier that delivers lasting protection in coastal and corrosive environments.

Coastal conditions demand purpose-built AM210 steel
Standard pre-painted steel often fails within 1 km of the coast – but UniCote® Coastal’s AM210 alloy stands apart, engineered specifically for marine environments where others falter.
Built for real projects
Proven on landmark coastal builds, UniCote® Coastal delivers corrosion resistance and design flexibility you can specify with confidence.
