Preventing Corrosion

How and why does galvanizing a metal help to prevent the corrosion of metals?

When you galvanize a metal, you coat it in zinc because zinc is a stronger reducing agent than other metals such as iron. As a result, when there is a scratch and the metal under the zinc is exposed, the zinc oxidizes instead of the metal underneath, protecting the metal underneath from corrosion.

Is this the only example where this would be true?
