Our customers often use the remarkably flexible round fiberglass rods as framing for a variety of structures like greenhouses, kites, and flag whips. 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.
We can accommodate large orders and custom cutting – please contact us at 206-632-6151 or info@goodwinds.com to speak with a composites engineer.
