U.S. Plastic Corporation Fibergrate Dynaform Square Tube 48475

A proprietary isophthalic polyester resin formulation offering resistance to a wide range of chemicals. All shapes except the solid square and rod also also provide a low flame spread rating of 25 or less (when tested according to ASTM E-84). 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 light weight, along with thermal and electric non-conductivity. Provides years of low maintenance service in areas where steel, aluminum or wood components were traditionally specified. Max. working temp. 150F. Often used in highly corrosive applications where stainless steel and other expensive components were once required. UV resistant. Solid rod does not provide low flame/spread ratings. Gray, unless otherwise stated. Corrosion resistance - providing long life in aggressive acidic or caustic environments. Lightweight and high strength - allowing for more dependable support-to-weight ratio than steel. Dimensional stability - maintaining the cross-section of structural shapes based on a low coefficient of thermal expansion. Non-conductivity - adding to personnel safety. Electromagnetic transparency - providing no impediment to the transmission of radio and microwave frequencies Tolerances: Angles: thickness +/- 10%, width and depth +/- 5%. .Channels: thickness +/- 10%, width and depth +/- 5%.
