Building a home near the coast is a dream for many Australians – panoramic views, fresh ocean air, and a relaxed way of living. But as anyone who’s lived near the sea will tell you, coastal environments are tough on materials. Salt, humidity, and constant exposure to the elements can wear down even the best finishes.

That’s why the materials you choose – especially for your roofing and cladding – matter more than ever. And one name you’ll want to remember in your decision-making is AM210. It’s the high-performance alloy that forms the backbone of UniCote® Coastal, a steel solution engineered for the unique demands of coastal construction.

Not all steel is created equal

At UniCote®, we offer a full range of painted steel solutions – each with its own unique purpose. But when it comes to coastal builds, UniCote® Coastal stands apart. It’s specifically designed to perform in marine-adjacent environments, where lesser materials can fail prematurely.

If your build is within 1000 metres of the ocean – especially in exposed or high-humidity areas – choosing a product without marine-grade credentials introduces long-term risk. That’s why AM210 is such a crucial benchmark. If you’re comparing steel alternatives, ask whether they match the performance of AM210. If they don’t, it’s worth thinking twice.

Long-term thinking, backed by science

Building by the coast is a high-investment, high-expectation decision. You want your home to be beautiful – but you also want it to last. UniCote® Coastal gives you that balance: visual appeal and serious protection, all backed by science and real-world testing.

We know the market is full of options. But when you understand what AM210 brings to the table, it becomes clear: this isn’t just another finish – it’s a smarter foundation for your coastal build.

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.
