Pultruded carbon offers extreamly high strength and stiffness. It have a uni directional fiber orientation, meaning the fibers run along the length of the tube.
This gives the best 'Tension strength' possible (if you try to stretch the rod to make it longer), However it does leave it vunerable to forces in other planes, such as crushing force if you were to stand on a rod that was laying on the ground.
Pultruded square comes with a square outer shape and a circular inner diameter. Use the option boxes to select the outside square size/inside hole size.
The price will automatically update with each selection. The square tube size is shown as x/y. This means the first figure (x) is the outside size of the square across the flats. The second figure (y) is the inner diameter (or the circular hole diameter). Sizes are in mm.
