（5）Primary Applications

• FPV & professional drones: arms, landing gear, tail booms

• Marine: masts, spinnaker poles, oars, flagpoles

• Outdoor & sporting goods: fishing rods, trekking poles, tent poles, avalanche probes

• Robotics & automation: lightweight arms, rollers, drive shafts, telescopic columns

• Automotive & motorsport: driveshafts, spoiler supports, roll-cage elements

• Medical devices: support tubes, X-ray table components

• Photography & film: jibs, sliders, tripod legs

• Measurement & construction: telescopic poles, temporary structures

All tubes are manufactured using the roll-wrapping process (table-rolled prepreg on precision-ground mandrels followed by oven cure and centerless grinding) ensuring void-free laminates, perfect inner surface finish, and consistent mechanical properties.

Full customization available: any diameter, wall thickness, color, surface finish, layup design, and secondary machining (tapers, slots, holes, threads, etc.).
