Liberty Pultrusions

West Mifflin, PA, United States

POLYURETHANE PULTRUSION Liberty Pultrusion manufacturers custom pultrusions utilizing Polyurethane resin technology. Urethane is 40% stiffer than Polyester, this allows for a stiffer profile or reduction in profile thickness by about 25% which reduces the profile weight and maintains the same stiffness as Polyester resin technology.

Our custom manufactured pultruded shapes come in a multitude of pultrusion resin system and colors that meet our customers’ specifications. We fabricate pultruded parts for value-added service with a quick response time. Our expert engineering staff can assist in the design of virtually any continuous cross sectional pultrusion profile.

Our Precision CNC Machined Parts are developed through our internal machined parts department experienced in fabricating parts made from fiberglass pultrusions and plastic sheets. We have precision machined high pressure laminates, glass polyester sheet, UHMW, HDPE, and other thermoplastic and thermoset sheet products.
