Finally manufactured a highly specific and customizable carbon fiber tube with lightweight and high strength properties. Their surface is 3K carbon fiber weave fabric, the carbon tubes have beautiful and amazing appearance. These roll-wrap carbon fiber tubing offer higher strength to weight ratio than is available in pultruded tubes.
