Fiberglass Round Bar

Fiberglass round bar is a kind of FRP composite material formed by pultrusion. It is a thermosetting elastic material formed by continuous glass fiber roving and resin drawn by pultrusion machine.
✔️ A Variety of Specifications.
✔️ Factory Direct Sales.
✔️ Accept Customized Services.

You can find insulating fiberglass rods in many electrical applications, such as insulators for overhead transmission lines. They are produced with continuous glass fiber roving and resin by pultrusion technology. The rich resin layer on the surface makes them have good corrosion resistance, and at the same time with insulation and non-thermal conductivity, so fiberglass rods are an alternative to wood, aluminum, or steel structural shapes in corrosive environments.

Fiberglass round bar is one of them, widely used in the electrical and power industries for insulations needs. A variety of specifications, as you choose, can be customized production! If you are looking for electrically insulating solutions, you can consider composites!

Q1: How do you ensure the quality of FRP products?

A: All products are manufactured in our own factory under strict ISO-based quality control. We perform raw material testing, process monitoring, and final inspection to ensure every panel meets strength, durability, and corrosion-resistance requirements.

Q2: Where can FRP products be used?

FRP products are ideal for chemical plants, wastewater facilities, offshore platforms, walkways, platforms, stairs, and other areas that require corrosion resistance, lightweight structure, and long service life.

Q3: Do you provide after-sales support?

Yes. We provide clear documentation, installation guidelines (if needed), and technical support. If any quality issue is confirmed after delivery, we offer replacement, rework, or other agreed solutions.

Q4: Can you help with project-specific requirements?

Absolutely. Our team can suggest the right resin system, grating type, and surface finish for your application, and provide drawings or design assistance to ensure project success.
