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. ThruFlow panels won’t succumb to rot or insect damage and are UV resistant. Whether you choose to install our panels on your family deck or in your commercial marina, ThruFlow will serve you through a lifetime of use and abuse.

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

The Legacy panels’ unique design allows 43% of sunlight to pass through uninterrupted. When installing decks, docks, and walkways, we rarely consider the wildlife being displaced underneath. But ThruFlow’s perforated construction protects native flora and fauna by providing the sunshine they need.

At ThruFlow, we pride ourselves on the safety of our products. The surface of our panels will never get hot under direct sunlight, leaving you free to enjoy your deck or dock in all weather. When installed in docks, marinas, and gangways, our panels’ open design protects against uplift caused by storms and strong winds. And the non-slip surface holds true wet or dry.

Our Legacy panel design has proven itself in commercial marinas and natural parks throughout the world. The research and development behind our Legacy panels have allowed ThruFlow to continue to grow and release new product lines. But our Legacy Series will always be the original.

Legacy Series panels are light weight and durable, allowing for ease of installation, while providing excellent protection.

The Legacy Series is made from short glass reinforced virgin Polymer producing extra durability against wear-and-tear, rot, insects and UV rays thus making them maintenance-free.

43% of the Legacy panel is ‘open’ allowing sunlight and storm surges to pass through.
