Metal gates look brilliant when they’re first installed. They’re solid, stylish – exactly what you want. But then rust creeps in. So, why does it happen and why is it such a headache to deal with?
What actually causes rust?
Rust forms when iron reacts with oxygen and moisture. And let’s face it, in the UK we’ve got plenty of damp air and rain to go around.
According to the Royal Society of Chemistry, rusting is simply iron reacting with water and oxygen over time.
If your gate isn’t properly treated or coated, it’s an open invitation for corrosion. Even the tiniest scratch in the paintwork lets moisture in, and once rust starts, it spreads – like a disease.
Why it’s more than just cosmetic
Surface rust might not seem like a big deal but leave it unchecked and it will be. Rust is like gate cancer for outdoor metalwork like metal balustrades. When that corrosion sinks in, the strength and structural safety can both be compromised, which is why quality materials and protective finishes matter so much from the start.

How to prevent it
Prevention is easier than repair. Look for galvanised steel or properly powder-coated finishes and keep an eye out for chips or scratches and touch them up quickly.
A bit of routine cleaning helps, too. Dirt traps moisture, and moisture feeds rust. Choose well, maintain it properly, and your gate and metal balustrades should stay strong.
