Fiberglass Tubes from R&G – Lightweight, Strong and Versatile

Fiberglass tubes (GFRP tubes) combine high strength with low weight and excellent corrosion resistance. At R&G you will find high-quality glass fibre tubes in a wide range of diameters and lengths, as round tubes, as a practical plug-in system and in telescopic versions. Whether for model making, drones, antenna and mast construction, kites or technical builds: here you will find the right fiberglass tube and can buy it directly online.

What makes R&G fiberglass tubes special?

Fiberglass tubes are made from glass fibre reinforced plastic, a combination of glass fibres and a cured resin matrix. This construction gives the tubes their characteristic properties:

• High strength and stiffness at very low weight.
• Corrosion-resistant, they do not rust and are unaffected by moisture.
• UV- and weather-resistant, and therefore suitable for outdoor use.
• Electrically insulating and non-magnetic.
• Easy to work with, meaning they can be cut to length, drilled and bonded.

Sizes, versions and connections

Our fiberglass tubes are available in many diameters, from slender tubes for model making to larger cross-sections for load-bearing builds. Depending on the application, choose between filament-wound tubes with particularly high strength and a clean surface, pultruded tubes for straight, rigid applications, and the GFRP/carbon plug-in system, which lets you slot tubes together and set the length you need. For extendable solutions, our telescopic poles are ideal. If you need a solid cross-section, our fiberglass rods are the right alternative.

Typical applications for fiberglass tubes

Fiberglass tubes are in demand wherever a good balance of weight, strength and weather resistance matters: in model and aircraft building as well as drones, in antenna, mast and telescopic structures, for kites and tent poles, in boat building and water sports, and in general technical builds, jigs and repairs. For especially stiff or light structures, our carbon tubes are a high-quality alternative.

Processing and accessories

Fiberglass tubes can be cut to length with a fine-tooth saw or a cut-off grinder. Wear a respirator and gloves, as glass dust is produced. For durable, load-bearing joints we recommend epoxy adhesives. Suitable cutting tools and the full range of resins and hardeners are also available at R&G.

Frequently asked questions about fiberglass tubes

How are fiberglass tubes made?

Fiberglass tubes are mostly produced by filament winding or pultrusion. Glass fibres are impregnated with resin and cured under defined conditions. Winding produces particularly strong tubes with a clean surface, while pultrusion creates straight, rigid profiles.

Which diameters and lengths are available?

R&G offers fiberglass tubes in many diameters and standard lengths. The plug-in system lets you combine tubes and set the length you need. The currently available sizes are shown in the product selection on this page.

How can fiberglass tubes be cut and joined?

Fiberglass tubes can be cut to length with a fine-tooth saw or a cut-off grinder, ideally wearing a respirator and gloves. They are joined permanently with epoxy adhesive or, depending on the version, via the plug-in system.

What is the difference between fiberglass and carbon tubes?

Fiberglass tubes are cheaper, electrically insulating and slightly more flexible. Carbon tubes are even stiffer and stronger at the same weight, but more expensive and electrically conductive. For many applications GFRP is the economical choice, while carbon is best for maximum stiffness at minimum weight.

Are fiberglass tubes suitable for outdoor use?

Yes. Fiberglass tubes are corrosion-, moisture- and UV-resistant and are therefore well suited to permanent outdoor use, for example for antennas, masts or poles.
