This square planter liner has been created out of galvanized metal, and then is powder-coated to provide seasons of use. These metal planter liners could stand on their own as planters, and will add a spot of color to your landscape or patio. All of our planter liners are galvanized, which means our metal has been dipped in zinc to protect from rust or any other type of deterioration. Then we powder coat the outside as well as the inside to negate the effects of constant moisture. All of our planter liners come with drainage holes. Choose from white, bronze tone, copper tone, or real copper at an additional premium. These metal or copper planter liners can be customized to your specifications as well. Just give us a call at 800-896-0978.
