Much like round pultruded carbon tubes, square carbon tubes are pultruded and have longitudinally-oriented fibers. The outer profile of these tubes is square, while the inner hole is round. Square carbon tubes are a great choice if you have an application that requires a square profile but the stiffness and lightness of a carbon fiber tube. Our customers often use these rods as stiffeners in foam surfboards and foam RC models.
