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 4 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 4 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.

How to Order
Getting a quote is straightforward. Send us your OD, ID, wall thickness, length, weave preference, and quantity — we respond with a factory direct price within 24 hours. For custom laminate schedules, our engineering team reviews your load case and recommends the optimal ply stack before production starts. Standard sizes in our existing tooling ship in 10–15 working days; custom mandrels add 7–10 days. Every order includes dimensional inspection reports and surface photos before shipment.
