Plain galvanized steel pool-walls have a tendency to rust and corrode, but if you purchase an inground vinyl-liner pool-wall that is polyester powder-coated over the galvnized steel, you protect the wall from rust and corrosion. We carry the exclusive “POLYSTEEL” polyester powder-coated vinyl-liner pool-wall, that will not rust or corrode like a plain galvanized wall, and will not bow, bend, or crack like a polymer-plastic pool-wall.Call 609-313-0300 for more information…Sincerely;Richard@paradisepoolandspa.com
