Fiberglass Dynaform® I-Beams

Fibergrate Dynaform™ pultruded fiberglass structural shapes are used in a wide range of applications, providing a unique combination of corrosion resistance, high strength, dimensional stability, and lightweight, along with thermal and electric non-conductivity. It provides years of low maintenance service in areas where steel, aluminum, or wood components were traditionally specified—often used in highly corrosive applications where stainless steel and other expensive parts were once required.
