Description: FRP pultrusion square tube, made of alkali-free glass fiber and phthalic resin, through continuous pultrusion process shaped equal section profiles.
Application: FRP square tubes are often used in chemical processing plants, Marine construction, food and beverage processing, oil smelting, paper industry, sewage treatment and transportation industries and other areas.
Features: It has corrosion resistance, light weight and high strength, good dimensional stability, and has the characteristics of insulation, non-thermal conductivity, beautiful and easy to maintain. Compared with traditional materials such as steel, aluminum, wood, it has almost no maintenance costs.
Specification: epoxy/polyester material
Colour and length are according to customer's requirements
We carry out standard GB13398-2008 [Hollow Insulation Tube, Foam Filled Tube and Solid Rod for Living Line Tool], which is higher than the International Standard IEC60855:1985 and IEC61235:1993.
