Galvanised vs Powder Coat vs Paint

Paint is the cheapest and the weakest. It is a thin skin, and the moment it chips on a gatepost or scratches under a load, bare steel is exposed and rust starts at the mark. On a farm that happens in week one.

Powder coat is a thicker, tougher baked-on finish, and it holds up better than paint to knocks. But it is still a coating on top of the steel. Chip it or crack it, and the same thing happens: water gets under the coating and the steel rusts, sometimes hidden until it lifts the finish off in sheets.

Galvanising is different in kind, not just degree. The whole frame is dipped in molten zinc, which bonds into the steel. It then protects the steel sacrificially, so it keeps working even where the surface is scratched. It is the finish used on farm gates and stockyards for exactly this reason.

That is why the Galvbike frame is hot-dip galvanised. More on what that means day to day in what a galvanised bike means for a farm.

If a bike is going to live outside, cross creeks and be pressure-washed daily, the finish is not cosmetic, it is whether the frame lasts. Paint and powder coat are fine for a bike that gets put away clean. Galvanising is for one that works.

Is galvanised better than powder coat for a farm bike?

Yes. Powder coat is tougher than paint but still a surface coating that rusts once chipped. Galvanising bonds zinc into the steel and protects it even where scratched, which is what a farm bike needs.

Does powder coat rust?

Not on the surface, but once it is chipped or cracked, water reaches the bare steel underneath and it rusts, often hidden under the coating.

Why is the Galvbike galvanised and not powder coated?

Because it is built to live outside and be hosed down every day. Galvanising protects the frame through knocks and scratches, where a powder coat would eventually fail.
