About Liberty Pultrusions | FRP Pultrusion Manufacturing

About Liberty Pultrusions FRP Manufacturing 


For more than 40 years Liberty Pultrusions has been a premier leader in the Fiberglass Reinforced Plastics (FRP) Pultrusion industry. We are a customer-focused business that provides quality, cost-effective solutions. Our aggressive pricing, precision, expertise, and superior product quality are the traits that sustain our business and keep our customers happy.

The pultrusion process allows us to provide high-quality products that are superior and longer lasting than other types of materials such as steel, aluminum or timber. FRP Pultrusions are corrosion resistant, non-conductive to electricity and heat and very lightweight. Please read the Benefits of FRP Pultrusion Over Other Materials page for more information.


In addition to being a premier supplier of custom composites, we are also a major producer of FRP structural shapes for use in the corrosion, construction and electrical industries.

Our structural pultrusions, pultruded fiberglass electrical shapes and pultruded fiberglass rod are used in a wide range of applications from fiberglass cooling towers and structural supports to flagsticks and snow poles to ladder rail channels and transformer spacer sticks.
