Legacy Series

The original ThruFlow™ panel, Legacy, is a revolutionary take on prefabricated panels for decks, docks and walkways. With its easy-to-assemble, maintenance-free design, you can spend less time caring for your ThruFlow products and more time enjoying them. Our flagship Legacy panel uses integrated short glass fibers for extra durability against wear-and-tear. Features include:


  • Maintenance-free

  • Easy to assemble with connecting tabs

  • UV Resistant

  • Non-slip surface holds true wet or dry

  • Allows 43% of sunlight to pass through uninterrupted to protect your dock against uplift caused by storm surge and strong winds

  • Open architecture is environmentally friendly to flora and fauna below your dock enabling them to thrive (recommended by the Army Corps of Engineers)


The surface of our panels will never get hot under direct sunlight, leaving you free to enjoy your deck or dock in all weather.

Legacy 4x4 panels are lightweight, durable, easy to install, and provide excellent protection.
