chain-link fence is sometimes called vinyl or color-coated. In this process, steel wire is first coated with zinc and then covered with a vinyl polymer coating that helps prevent rust and adds color. The vinyl is generally added to both the framework and the fabric of the fence. Some chain-link fence products use an aluminized coating to cover the steel in place of the zinc that creates a highly reflective finish. Regardless of the finish, all chain-link products offer a durable, economical fence system.
