    • ~0.005 reduction on outer diameter (OD)."
    • This removes the outer cello wrap gloss finish.
    • Sand outer diameter to specified thickness.
    • Patterns will likely distort in appearance
    Please select a value within the allowed range.

If you are requesting bulk discounts, cutting, or standard sanding services only, we will send you a cart with your product selections. You may enter your shipping information and purchase directly at that time. Please note, the cart will not allow edits to the quote. Any changes will have to be completed by our team. If we do not have enough information to complete your quote we will reach out to you directly. If you are requesting additional services or custom sanding, a team member will reach out to you to finalize a quote.

If you request a custom length you will be charged for a full length item (or items if more than 1 is needed to meet your request) plus a cutting fee. You will then be shipped the item sized to your specification and any remaining length of the orginal item (drops). Sanding also incurs a fee which will be included in the quote. All items that have been sanded or cut may not be returned.

Estimated lead time for quantities greater than what is Available Now is expected to be between 2 and 4 weeks.
If there is an Available Now quantity listed above, it indicates our quantity in stock. Orders placed today for this quantity or less are expected to ship the next business day.

Unlike metals which have similar properties in all directions (isotropic), the properties of composites are varying, dependent on the orientation of the fibers in each layer. 

Roll wrapped tubing is manufactured using multiple layers of pre-preg carbon fiber (and if noted, other) materials. In general each layer is about 0.006 inches thick which means that a tube with a wall thickness of 0.060 inches will typically be composed of 9-10 individual layers of carbon fiber. The number of layers(plys) allows us to vary the orientation of the fibers throughout the thickness, creating a high performance, engineered product.
  • Fabric Tubing has an outer ply of woven material (denoted below as 0°/90°). Typically this outer ply is a 2x2 twill weave (diagonal appearance seen below) but it can also be a plain weave (small checkerboard), spread tow (large format plain weave / checkerboard) or other off-axis weave such as a braid. The core of these tubes are almost always comprised of multi-directional "uni" plies.
  • Uni Tubing is comprised of multi-directional "uni" plies just like the fabric tubes however instead of the outer ply being fabric, it is unidirectional and most typically oriented at 0° (fibers running the length).

  • 0° fibers maximize bending stiffness and run along the length of the part. Consider bending a tube over your knee.
  • 45° fibers maximize torsional stiffness and are typically plied together in an opposing manner, i.e. ±45°. Consider twisting a tube like a vehicle's driveshaft.
  • 90° (or "hoop") fibers maximize crushing stiffness and generally assist in overall durability. Consider laying a tube on the ground and stepping on it.

Technical Specifications

Radius of Tubing

The inner and external corner radii are measured by hand with a radius gauge with no tolerance called out.
  • Internal Radius: 5/16”
  • External Radius: TBD, ~3/8”.

We cannot supply theoretical values for this tube at this time. For specification sheets and other data we can supply please review our Technical Spec page.
