Fiberglass rods

Fiberglass Rods

Solid fiberglass rods have thousands of industrial and hobby uses. Because fiberglass rods are not electrically conductive, they are a great material for antennas. Solid fiberglass rods are also frequently used as a strengthening core in applications where conductivity is an issue.  Inexpensive, flexible, durable, and strong, our fiberglass rods are available in stock lengths of 48” and 72”, from .062” in diameter to .750” in diameter.  Other lengths and diameters are available by custom order and are subject to minimum order quantities.  Contact us at 360-588-4785 or info@goodwinds.com for more information.
