Pultruded Fiberglass (FRP) Beams

Liberty Pultrusions is a US manufacturer of pultruded fiberglass (FRP) beams. Fiberglass beams — more precisely, pultruded FRP (fiberglass-reinforced polymer) beams — are structural profiles fabricated by pulling continuous glass fiber reinforcements through a resin bath and then through a heated die to cure into a fixed cross section. The result is a high-performance, composite beam that maintains consistent shape, strength, and durability over long lengths. Unlike traditional materials, Liberty Pultrusions pultruded FRP beams deliver a combination of mechanical, chemical, and environmental advantages that make them ideal in many demanding applications.
