FRP square tube
Fiberglass reinforced polymer / Fiberglass reinforced plastic (FRP) pultrusion profiles/ pultruded profiles include round, square, rectangular tube; handrail, guardrail; grating, floor grid; channel; angle; rod and plate.
FRP square tube is made of composite polymer with fiberglass as the reinforced material. It is widely used in structural construction, chemical projects, water treatment projects for supports and beams, Specialling the 50mm square tubes are usually used to assemble the industry handrails and other handrails.
The characteristic of FRP square tube is follows:
1, Corrosion Resistant
2, Light Weight, High Strength and Impact & Fatigue Resistant.
3, Non-Conductive & Non-Magnetic
4, Easy Maintenance
5, Fire Retardant
6, Dimensional Stability
7, Easy Assembly
