ThruFlow Legacy XP Series Decking - with Tabs

ThruFlow Legacy XP Series Decking delivers a balanced blend of durability, water flow, and long-lasting performance for residential and commercial waterfront applications. Legacy XP panels are ThruFlow's flow-through — or throughflow — design, letting water and sunlight pass through the surface instead of pooling on top. Positioned between ThruFlow's cost-focused Impact series and its ultra-reinforced Surge line, Legacy XP uses reinforced polymer construction to deliver dependable strength without the added cost of over-engineering. Unlike Aqua-Dek's large, barefoot-friendly panels, Legacy XP is built around an optimized open surface area that prioritizes structural integrity and water flow — a design choice suited to docks, walkways, and transitional waterfront spaces where drainage and durability matter as much as comfort underfoot. The open-grid design reduces hydrostatic pressure and keeps the deck surface stable season after season, with UV-stable, slip-resistant panels that stay virtually maintenance-free under constant sun and moisture exposure. Key Features Reinforced polymer construction for dependable strength Optimized open-grid design improves drainage and light penetration UV-stable, slip-resistant, low-maintenance surface Interlocking panel design for straightforward installation Panel Sizes Available in 1' x 3', 1' x 4', and 1' x 5' interlocking panel sizes — the 1x3 suits tight walkways, 1x4 fits standard dock runs, and 1x5 covers larger deck and marina installations.
