Large Diameter Carbon Fiber Tube

Large diameter carbon fiber tubes from 100mm to 300mm OD, roll-wrapped in our Shenzhen factory with custom laminate schedules for structural and industrial applications. Wall thickness 2mm to 15mm — thick enough to resist buckling at scale. Pultruded options available up to 8 meters single-piece. Factory direct pricing, ISO 9001 certified.

Product Details

When you move past 100mm OD, carbon fiber tube design changes. The wall gets thicker, the mandrel gets heavier, and curing requires tighter temperature control — but the payoff is real. A 200mm OD CF tube with 5mm wall weighs roughly one quarter of a steel tube with the same bending stiffness, and it never rusts. That weight ratio is why large diameter carbon fiber tubes are replacing steel and aluminum in wind turbine components, industrial rollers, and structural columns where every kilogram matters.

At this scale, roll-wrapping is the primary manufacturing method. We wrap pre-preg layers onto precision-ground steel mandrels up to 300mm OD, building wall thickness layer by layer. This gives us full control over the laminate schedule — ±45° plies for torsion, 0° for axial load, 90° for hoop strength, or a hybrid stack tailored to your application. Pultruded options are available for straight tubes up to 8 meters long, but roll-wrapped remains the go-to for anything that needs custom fiber orientation or non-standard ID dimensions.

Our Shenzhen factory runs mandrels from 20mm to 300mm OD. Each large diameter tube is measured at a minimum of five points along its length for OD, ID, roundness, and wall thickness uniformity — more checkpoints than standard tubes because geometric errors amplify at larger diameters. Buying large diameter CF tubes factory direct from China means you skip trading company margins and deal directly with the engineering team that designs your laminate. We ship in reinforced wooden crates, not flimsy cardboard, because a dented 200mm tube is scrap.

Applications

  • Wind turbine and renewable energy — Spar caps, nacelle frames, and blade root reinforcement where high bending stiffness and zero corrosion are non-negotiable
  • Industrial rollers and mandrels — Printing, film casting, textile winding; large CF rollers run faster than steel because lower mass means less deflection and vibration
  • Structural columns and supports — Exhibition frameworks, cleanroom pillars, and lightweight building elements where a 200mm CF column replaces a 400mm steel section
  • Radar and communication masts — Large diameter tubes as antenna mounts and radar pedestals; CF is RF-transparent so the structure won’t interfere with signal transmission

Why Choose YTCarbon

  • We exhibited at the 2025 World UAV Expo — see what a real carbon fiber factory puts on the table. Our large diameter capability is not a catalog claim; it’s a production line we run daily, with mandrels up to 300mm OD and pultrusion up to 8 meters single-piece
  • Custom laminate for every diameter. We don’t offer one generic layup. ±45° for torsion-heavy rollers, 0° for axial-loaded columns, hybrid stacks for multi-axis loads — your load case drives the ply schedule
  • Thick-wall capability up to 15mm. At large diameters, thin walls buckle under their own weight. We build walls from 2mm to 15mm and help you find the lightest wall that meets your safety factor
  • Factory direct from Shenzhen. No trading company markup, no communication lag. You talk to the production team, get real photos of your tubes on the line, and receive pricing that typically saves 15–30%

Certifications

Every large diameter carbon fiber tube we ship carries documented quality credentials. Our facility holds ISO 9001 certification for quality management, and our carbon fiber materials are RoHS and CE compliant — essential if you’re selling into the EU or supplying customers who need traceable material documentation.

Frequently Asked Questions

+ What is considered a large diameter carbon fiber tube?
In our product range, anything with an outer diameter of 100mm or above. The manufacturing process shifts from standard pultrusion to roll-wrapping as the dominant method, because large-diameter pultrusion dies are expensive and limited in availability. Most CF tube suppliers cap out at 80–100mm OD — our tooling goes to 300mm, and our pultrusion line handles standard diameters up to 8 meters single-piece.
+ Can you make carbon fiber tubes larger than 300mm OD?
Yes, for specific projects we can go beyond 300mm using filament winding or oversized roll-wrapping. These are custom quotes — send us your OD, ID, wall thickness, and length requirements and we’ll confirm feasibility within 24 hours. For reference, our 8-meter pultrusion capability covers a wide range of standard diameters at volume, and custom diameters simply require a new mandrel or die.
+ What wall thickness does a large diameter carbon fiber tube need?
At large diameters, buckling is usually the governing failure mode — not material strength. As a rough guide: 3–5mm wall for 100–150mm OD under moderate loads, 5–8mm for 150–200mm OD, and 8–15mm for 200mm+ OD in structural applications. The exact number depends on your span, loading, and safety factor. Send us your load case and our engineering team will recommend the minimum wall thickness that meets your requirements.
+ How do you ship large diameter carbon fiber tubes?
Each tube is wrapped in bubble film, placed inside a PVC sleeve, and packed into a reinforced wooden crate. For tubes over 2 meters, we use custom cradles that prevent bending during transit. Shipping by sea is standard for large diameter tubes — air freight gets expensive quickly above 150mm OD. We handle all export documentation from our Shenzhen facility, and our 8-meter pultruded tubes ship in custom-length crates designed for container loading.
+ How long does it take to produce a large diameter carbon fiber tube?
Standard sizes in our existing tooling range ship in 10–15 working days. Custom diameters that require new mandrel fabrication add 7–10 days. Each large diameter tube gets a minimum five-point dimensional inspection along its length — more checkpoints than our standard tubes. Once tooling is set, our pultrusion line can run high volumes of tubes up to 8 meters long efficiently.
