Will galvanized steel rust in water?
The bond that forms between the steel and zinc when materials are hot-dip galvanized is self-healing. This means that, when the zinc coating comes into contact with water, it reacts by building up extra protection for itself. This protection increases its rust and corrosion resistance.
What lasts longer zinc or galvanized?
A product that is hot dip galvanised will have a thicker coating, meaning it will last far longer. Hot dip galvanised coatings give superior protection against corrosion. The images below show that zinc plated gate hardware will rust over time.
