Buying advice

When choosing carbon fiber rods, consider the primary loading direction: unidirectional rods are stiffest along the fiber, while woven provide balanced strength. For precision applications, look for pultruded rods with tight tolerances. Always verify the actual diameter and length match your needs, and be prepared to cut or sand ends. For structural use, higher price often correlates with better quality control and surface finish.
