Will galvanized steel rust?
Galvanized steel takes a long time to rust, but it will eventually rust. This type is carbon steel that has been galvanized or coated with a thin layer of zinc. The zinc acts as a barrier preventing oxygen and water from reaching the steel, providing advanced corrosion protection.
