Zinc plating, often called bright zinc, is an electro-plating process, the same as chrome, nickle, cadmium etc. The finish will be very bright and shiney when new, but dulls over time (slowly).

Galvanized steel has the zinc applied either by dipping into molten zinc, or by a mechanical process where the zinc is pounded by tumbling in a mix of zinc powder and steel balls. Both processes apply a much thicker coating than plating does, and it has the dull finish of a Cyclone fence immediately.

So, yes, it is zinc, but no it isn't the same.



a much thicker layer than plating does
