Galvanising vs Powder Coating: Which Finish?

Steel is strong, but without the right finish it rusts. Two of the most common protective finishes are hot-dip galvanising and powder coating — and they serve different purposes.

**Hot-dip galvanising** coats steel in a layer of zinc by immersing it in molten zinc. It offers excellent corrosion resistance, especially outdoors, and is self-sacrificing — the zinc corrodes instead of the steel.

**Powder coating** applies a dry polymer that's cured to a hard, attractive finish. It comes in many colours and offers good weather resistance, but it can chip on impact.

**The best of both worlds:** For outdoor steel in harsh environments, we often recommend a dual-coat system — galvanise first for corrosion protection, then powder coat for colour and UV resistance.

Our team will advise on the right finish based on your project's location, exposure, and aesthetic goals.
