Description
FRP Pultruded Tubes are hollow fiberglass-reinforced plastic profiles manufactured through the pultrusion process. Available in round, square, and rectangular shapes, these tubes can be produced as structural pultrusions or electrical-grade pultruded shapes.
Using different resin systems, glass reinforcements, and color options, pultruded fiberglass tubes can be customized to meet specific mechanical, fire-retardant, and electrical performance requirements. Compared with traditional materials such as steel, aluminum, and wood, FRP pultruded tubes offer superior corrosion resistance, lighter weight, and longer service life, while maintaining excellent strength and dimensional stability.
