Products include pultruded, I-Beams, Channels, Angles, and Supergrate Pultruded Grating. The lightweight nature of this FRP structure reduced installation costs without sacrificing strength or durability. The impact on the sand dune environment is limited due to the open area of the Supergrate Pultruded Grating. This design allows for sand and water to pass through the walkway, minimizing sand build-up and wave damage. It also permits sunlight to pass through so stabilizing vegetation can continue to grow.
