ThruFlow Impact Series Decking - with Tabs

ThruFlow Impact Series Decking delivers dependable performance and is proven for a wide range of waterfront applications. As the foundational product in the ThruFlow lineup, Impact panels provide excellent drainage and light penetration through an engineered open-grid design, helping reduce hydrostatic pressure on docks, walkways, and shoreside surfaces. Like all ThruFlow flow-through decking, Impact panels let water and sunlight pass through the surface instead of pooling on top. Unlike Aqua-Dek's large, barefoot-friendly panels, Impact focuses on versatile, everyday performance with standard polymer construction that balances strength, economy, and long-term durability — a practical entry point into the ThruFlow line for residential docks, poolside paths, and light-to-moderate traffic areas. The non-corrosive polymer formula resists rot, mold, and moisture damage, staying UV-resistant, slip-resistant, and virtually maintenance-free in environments exposed to sun and water year-round. Key Features Engineered open-grid design for efficient water drainage Slip-resistant, UV-stable polymer surface Easy, interlocking panel installation with connecting tabs Non-corrosive, low-maintenance construction Panel Sizes Available in 1' x 3', 1' x 4', and 1' x 5' interlocking formats to fit walkways, standard dock runs, and larger deck or marina installations.Specifications Board thickness: 1.2" Board width: 11.6" Recommended joist span: 12" on center Surface pattern: Grated
