Galvanized steel shouldn't rust, but sometimes galvanizing can wear down and rust the metal. Often, the zinc used for galvanized steel corrodes rather than the actual metal to prevent rusting. When the zinc is all gone, that's when the rust really happens. You can remove rust from galvanized steel, but you will need to repair the rusted areas to prevent the rust from simply returning when the metal is exposed to moisture again.
