Latham's polymer wall system is made from totally non-corrosive materials. This contributes to longer liner life due to reduced wall abrasion. Polymer pools are also better to suited to increasing popular salt systems, which can accelerate corrosion. Latham's exclusive Graphex and Elite polymer composite panels and ultra-rigid Deluxe panels reduce the potential of warping and bowing due to thermal expansion of traditional polymer panels. Latham polymer panels offer premium performance without premium pricing. Latham's exclusive SureFit coping system has a proprietary bead and a PVC locking system that ensures that the bead will not come out of the track. Latham's Graphex and Elite Wall Panels & Braces carry a lifetime, non-prorated, transferable warranty.
