With deep grooves on its underside, Eon decking is stiff, strong, and light. No fasteners are visible thanks to a hidden clip system. Its non-slip surface actually becomes less slippery when wet. It comes in six different colors and, for plastic, is a great way to fool your guests into thinking it's real wood.
Eon, from CPI Plastics Group Ltd., $2.49-$2.59/lineal ft.; 100% polystyrene; 25-year limited warranty
