Each piece has a clear polyurethane finish on it. Many people want their piece to rust for the rustic look and it will take a number of years for that to happen. These pieces are made from heavy steel so they will last a very long time. If you do not want your piece to rust be sure to spray another coat of poly on it every year or so if left outside. If they are indoors they will be fine without spraying them. You can get the spray at most stores.
