Product Description

Product Description

Product Overview

At SYCarbonFiber, we specialize in engineering and manufacturing high-performance carbon fiber tubes suitable for all types and models, from ultra-thin hollow tubes to thicker structural variants. Available in 1K, 3K, and 12K fiber formats, our tubes are ideal for use in drones, robotics, CNC equipment, automotive, sports gear, and other lightweight structural applications.

We utilize aerospace-grade T700 or T800 carbon fiber combined with high-performance epoxy resin to ensure an exceptional strength-to-weight ratio, outstanding stiffness, and a clean, professional woven finish. Each tube is manufactured with precise roundness and straightness control (≤0.2 mm/m deviation).

From standard dimensions to fully customized specifications—including fiber tow count, wall thickness, weave type, and surface finish—we support a wide range of application needs. Popular sizes are available for immediate shipment (3–5 business days), while custom orders can be fulfilled within 15–20 days. Expedited production is also available in as little as 48 hours.

SYCarbonFiber is your trusted partner for all-model carbon fiber tubing, combining technical expertise with fast delivery and global reliability.

We offer end-to-end support, from material selection and design optimization to performance validation using Finite Element Analysis (FEA).

Common specifications are in stock and ship within 3 to 5 business days. Fully customized tubes are delivered within 15 to 20 days, with rush production available in as little as 48 hours.

SYCarbonFiber is a global supplier of advanced carbon fiber tubing, trusted for precision, reliability, and performance across industries.

FAQ

 Q1: What's the maximum length for your Carbon Fiber Straight Tubes, and how do you handle transportation?

Our pultrusion equipment can theoretically produce any length, but considering transport limitations, standard lengths are 6 meters and 12 meters. For extra-long products we can manufacture in segments for on-site assembly using specialized connectors, with connection strength no less than 85% of monolithic performance. For transportation, we have professional heavy cargo logistics partners providing nationwide delivery.

Q2: What advantages do carbon fiber straight tubes have compared to traditional steel or aluminum tubes?

A2: Three main advantages: First is light weight - 80% lighter than steel tubes, 50% lighter than aluminum tubes. Second is high strength, especially fatigue strength far exceeding metallic materials. Third is corrosion resistance with no rust concerns whatsoever. Yes, prices run higher, but from total lifecycle cost perspective, they're economical.

Q3: What cross-sectional shapes can you make, and do you have standard specification charts?

A3: We can produce round, square, rectangular, I-beam, L-shape, T-shape, and various other cross-sections. Standard products have detailed specification charts including outer diameter, wall thickness, length, and other parameters. Custom cross-sections require tooling with mold costs ranging 5,000-20,000 yuan depending on complexity, but costs get distributed across product pricing during volume production.
