Frequently Asked Questions
What are GFRP tubes made of?
GFRP tubes are made from continuous glass fiber strands impregnated with epoxy, polyester, or vinyl ester resin, then cured through pultruded GFRP tubes or filament-wound fiberglass tubes processes. This creates a hollow, lightweight profile with high mechanical strength and corrosion resistance.
Are fiberglass tubes waterproof?
Yes, GFRP tubes are inherently waterproof and resistant to moisture absorption, typically below 0.25%. This makes them suitable for marine masts, underwater applications, and outdoor structures exposed to constant rain or humidity.
Can GFRP tubes replace aluminum tubing?
Yes, when comparing GFRP tubes vs aluminum tubing, fiberglass is the popular choice in applications needing non-conductivity, corrosion resistance, or weight reduction, such as drone frames, tent poles, and electrical conduits, though aluminum retains an edge in pure stiffness.
What is the maximum length of a GFRP tube?
Standard GFRP tubes are manufactured up to 6–12 meters in a single continuous length via pultrusion, with longer lengths achievable through jointed sections or custom filament-winding processes for specific project requirements.
Do GFRP tubes conduct electricity?
No, GFRP tubes are fully non-conductive and are widely used in high-voltage cable ducting, telecom conduit systems, and electrical utility poles where dielectric strength fiberglass tubes are essential for insulation and safety.
What is the difference between pultruded and filament-wound GFRP tubes?
Pultruded tubes have fibers aligned mainly lengthwise for high axial strength, while filament-wound tubes have fibers wound at angles for superior hoop/pressure strength, making them better suited for pipes and pressure vessels.
