Fiberglass Fabrication

We can assist in the engineering, design, and fabrication of your finished structural fiberglass system. When corrosion, electrical conductivity, RF transparency or weight, present a problem, structural fiberglass provides the answer. Structural fiberglass is a very cost effective solution when traditional materials cannot meet the demanding challenges of your application. 

Molded Grating

Molded Grating

UltraGrate Molded Fiberglass Grating is a hand lay-up composite of resin and continuous glass fiber strand that is thoroughly wetted out and woven through an open mold. Our UltraGrate FRP Molded Grating is an excellent alternative to metal grating where rust, corrosion, or chemical attacks are problems.

Fiberglass Electrical Shapes

Fiberglass Electrical Shapes have outstanding electrical properties and are designed to support and electrically isolate components in power control and distribution equipment.  Reinforced with fiberglass, they are strong, stiff and stable.

The Liberty Pultrusions Process

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 light weight. Please read the Benefits of FRP Pultrusion Over Other Materials page for more information.
