Fiberglass Round Rods | Strong Lightweight Reinforcement


Fiberglass Round Rods – Strong, Lightweight, and Versatile

TAP Plastics Fiberglass Round Rods deliver exceptional strength-to-weight performance for a wide range of industrial, commercial, and DIY applications. Made with 65%–75% glass fiber content, these rods provide maximum durability while remaining lightweight and easy to work with.

Available in 1/8", 3/16", 1/4", 5/16", 3/8", 1/2", 3/4", and 1" diameters, fiberglass rods can be ordered in:

  • Standard 6-foot lengths (oversize shipping applies)

  • 3-foot lengths (no oversize fee)

  • Custom lengths (specify in checkout comments)

Fiberglass rods are valued for their ability to maintain micro-structural integrity under stress while resisting corrosion, moisture, and temperature changes. They can be easily fabricated with common tools such as a hacksaw or tile saw, making them a reliable option for professionals and hobbyists alike.

Common Applications:

  • Pool and spa service contractors: reinforcement for resurfacing and remodeling projects

  • Outdoor gear and sporting goods: structural supports for bicycle packs, tents, kites, and frames

  • Industrial and manufacturing: lightweight reinforcement where metal would corrode or add excess weight

  • DIY projects: strong, cut-to-size rods for creative structural designs

Round Rod Tolerances:

  • 1/8" to 1/2": ±.005"

  • 3/4": ±.008"

  • 1": ±.015"

Whether you need structural strength, corrosion resistance, or lightweight support, fiberglass round rods are a cost-effective alternative to metal rods that excel in demanding environments.

Choose Your Preferred Length to Save on Shipping

We offer flexible length options for 6-foot rod, tube, and rollstock materials.
To help you avoid costly carrier surcharges, choose the option that works best for your needs:

  • Standard 6-Foot Length (Oversize)
    Carrier-mandated oversize fee applies due to package dimensions exceeding 48”. This charge is added by UPS/FedEx—not TAP Plastics—and covers manual handling of long items. Only one oversize fee is applied per order.

  • Cut at 3-Foot Lengths (No Oversize Fee)
    We'll cut your item in half at no additional cost to help you avoid the oversize shipping charge. Perfect for smaller projects or convenient handling.

  • Custom Length (Specify in Checkout Comments)
    Need specific sizes? Select “Other (specified in comments).”
    Custom cutting is available—some requests may incur a labor fee. We’ll contact you with details before processing.

ⓘ Why the Fee?
UPS and FedEx charge extra for packages over 48" long—including required padding—for manual handling. These oversize fees apply on top of regular shipping rates, and may also apply to heavy or extra-long packages. TAP applies a flat fee to help cover these added carrier costs.
