Carbon Fiber Square Rod and Square Tube
Square-section carbon offers a flat mounting face and predictable stiffness that round stock cannot match, which makes it useful for jigs, fuselage doublers, and reinforcing structures where a straight edge helps. This category collects carbon square tube in a range of sizes so builders can pick the cross section that suits a given job.
Square Hole and Round Hole Options
The tube is offered in two internal formats. Square-hole tube gives a uniform wall on all four sides, while round-hole tube leaves more material at the corners and accepts a round rod or wire through the center. Both are available in a variety of outer sizes so you can step up or down as a project requires.
These rods are sold with a minimum order quantity, and you can mix sizes and hole types to reach that count, which lets you stock several sections at once rather than a single length.
Browse the square carbon sizes listed on this page to find the section your build needs.
