ThruFlow Deck System

ThruFlow Decks

ThruFlow panels are UV resistant and therefore keep your deck looking new for many more years than other building materials.

ThruFlow is resistant to rot and insects and absolutely no treating is required. ThruFlow panels come in a variety of colours to suit the look of your home and stay cool to the touch even in the hot summer sun. The No-Maintenance aspect will surely have you enjoying your deck rather than working on your deck.

ThruFlow Docks

ThruFlow Docks

ThruFlow's number one application use is in Pre-Fabricated and Permanent dock systems.

ThruFlow's interlocking decking system is the best dock decking panel due to its water resistance, anti-slip surface and grated design. ThruFlow is light weight so it allows for easy installation. Being that ThruFlow is grated it can also protect your dock from the up lifting wave and storm surge effects. The grated design also makes ThruFlow the environmentally friendly choice because it allows sunlight to penetrate the surface allowing S.A.V. to grow.

ThruFlow Storage

ThruFlow Storage

Looking to utilize attic space? Thruflow works as a ventilated panel, keeping air flowing while allowing you to walk freely though-out. ThruFlow also works well for damp basements. The applications for ThruFlow are endless.

ThruFlow Walkways

ThruFlow Walkways

ThruFlow is the ideal choice for building a walkway. Its open design allows debris to pass through keeping your non-slip walkways clean and safe. Its strength and durability are enough to take the punishment of any high-traffic walkway.

ThruFlow is designed to be the finished walkway for a dock, deck, patio, or any outside or inside flooring structure. It is also designed to be used in conjunction with metal, wood, aluminum or other similiar substructures.
