What are Fiberglass Reinforced Plastic (FRP) Structural Shapes, and what are they used for?

FRP I-Beam
FRP I-Beams were used in this restaurant as it looks great and compliments the beautiful design.

FRP Structural Shapes are Beam, Angle, Channel, Plate, Rod, Tube and other Custom Shapes/Sizes made with pultruded Fiberglass Reinforced Plastic instead of traditional materials like steel. This gives them certain advantages that are similar to our Molded and Pultruded FRP Grating.

At National Grating we don’t just sell FRP, we sell FRP solutions. Part of that offering is in the form of FRP Structural Shapes like Fiberglass Beam, Fiberglass Angle and Fiberglass Tube. On this page we will go over what these FRP products are, and what they are used for.
