Solid Fiberglass Rods

Our customers often use round fiberglass rods as structural support, framing, and fabric reinforcement. Perhaps you’re making antennas, flags, tarp containment, or boat covers. The opportunities are endless! Also known as glass fiber rods, solid fiberglass rods are available in black or white, are inexpensive, non-conductive, and extremely durable. We stock solid round fiberglass rod sizes from .062” to .750” in diameter and up to 12 feet long for custom cut orders. All lengths listed below are +/- 0.25″ and all diameters listed are +/- 0.005″.

We can accommodate large orders and custom cutting – please contact us at 206-632-6151 or [email protected] to speak with a composites engineer.
