Pool coping is the frame around the edge or lip of your pool. Pool coping serves multiple purposes for your vinyl liner pool. First, it is the decorative frame around the edge of your pool which then transitions to your decking. The second purpose of swimming pool coping is to give the swimmers an edge to hold onto while also helping to move any splashed water away from the edge of the pool. The third purpose of pool coping in a vinyl liner pool is to help cover the aluminum coping track underneath, which serves as the connection point for the actual vinyl liner to hang. Though coping and decking are often paired, the coping can be both functionally and visually distinct from the rest of the deck.
