DECKING®

Unlike ptl and other composite deck boards, this decking is built tough with WEARDECK® Super-Span Technology, delivering strength from the inside out. Its enhanced wood-free design is reinforced with fiberglass, making it rotproof, rustproof and impervious to wood-born insects.This powerful ingredient ensures that the Marine Grade Decking® holds up exceptionally well under high live loads with durability that lasts a lifetime.
