Duplex Coating for Cairn Homes

Discover how Galco protected 16.5 tonnes of steel for Cairn Homes with a Duplex Coating system combining Hot Dip Galvanizing and Galvacoat paint.

Residential projects face a unique challenge: they must not only look good on day one, but they must also endure.

From balconies and balustrades to staircases and canopies, exposed steel components are constantly under threat from Ireland’s ever-changing climate. Corrosion, UV degradation, moisture, and mechanical damage can all take their toll.

But Cairn Homes doesn’t settle for short-term fixes. Known for exacting standards and a meticulous eye for detail, they needed long-term protection with no compromises — and Galco delivered.

Thanks to seamless collaboration with Marcus P Graham Ironworks Ltd., we ensured that every steel component would look sharp today — and stay that way for decades to come.

Protection That Works in Harmony

For this project, Galco applied a complete Duplex Coating System across 16.5 tonnes of structural steelwork:

Hot Dip Galvanizing: A time-tested process that bonds zinc to steel at the metallurgical level. It provides uniform corrosion protection, is self-healing at cut edges, and requires zero maintenance, even in the harshest Irish conditions.

Galvacoat Paint System: Specially formulated to adhere to galvanized surfaces, Galvacoat offers superior colour retention, flexibility, and resistance to cracking or peeling — far beyond what conventional paints can achieve.

The RAL 9005 black finish delivered a bold, modern aesthetic that aligned perfectly with the client’s architectural vision.

These two systems don’t just coexist — they reinforce one another. The galvanizing protects the steel. The paint protects the zinc. That’s synergy in action.

Tough. Beautiful. Built to Last.

The result? A sleek, high-performance finish that’s as durable as it is striking. With reduced maintenance, lower lifecycle costs, and long-term visual appeal, the Galco Duplex Coating System delivers real value for contractors and homeowners alike.
