No Sanding - Product comes in original finish
Standard Sanding - Matte, smooth finish that is paint/bond ready
- ~0.005 reduction on outer diameter (OD)."
- This removes the outer cello wrap gloss finish.
Custom Sanding - Need to meet a specific outer diameter
- Sand outer diameter to specified thickness.
- Patterns will likely distort in appearance

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.

Very long continuous fibers add to strength and stiffness. Excellent for torsion, long single-piece tubes, and a unique aesthetic. Most economical for larger scale production.

Round Tubes and Rods - Axial Tension and Compression

Notes

Tension uses positive notation and compression uses negative notation.
End conditions are critical when considering buckling:
- Fixed = constrained in both translation and rotation.
- Pinned = constrained only in translation (ie. bolted joints).
- Free = not constrained (similar to a cantilevered end).
Long, skinny parts in compression are more succeptible to fail in buckling
Only parts in compression can fail in buckling

A green highlight indicates a valid input.
A red box indicates an invalid input.

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.
