Top 10 Manufacturers of Fiberglass Tubes and Tubing in 2025

The global fiberglass tube market is booming, projected to reach new heights in the coming years. Driven by demand from construction, aerospace, marine, and electrical industries, the need for strong, lightweight, and corrosion-resistant tubing has never been greater. However, with so many companies claiming to be the best, how do you, as an engineer, procurement manager, or DIY enthusiast, choose the right supplier?

Selecting the wrong manufacturer can lead to project delays, cost overruns, and even safety hazards. The right partner, on the other hand, delivers not just a product, but reliability, technical expertise, and value.

To simplify your sourcing process, we've compiled a comprehensive list of the top 10 fiberglass tube manufacturers in 2025. This list is curated based on factors like global reputation, product quality, technical innovation, range of offerings, and customer service.

Why the Choice of Manufacturer Matters

Before we dive into the list, let's understand why this decision is critical. Fiberglass tubes are not a generic commodity. Their performance is determined by:

Resin Formulation: Epoxy, polyester, and vinyl ester resins offer different properties in terms of chemical resistance and temperature tolerance.

Fiber Orientation: The alignment of the glass fibers dictates strength and flexibility.

Manufacturing Process: Pultrusion, filament winding, and centrifugal casting produce tubes with distinct characteristics.

Quality Control: Consistent diameter, wall thickness, and surface finish are signs of a superior manufacturer.

A top-tier manufacturer excels in all these areas, providing certified, reliable products backed by engineering support.

8. Bedford Reinforced Plastics

Bedford focuses on custom pultrusion and is known for its hands-on customer service and flexibility. They cater to both large and small orders, making them an excellent partner for startups and businesses with evolving needs. Their ability to handle smaller custom runs without sacrificing quality is a significant advantage for companies prototyping or in low-volume production.

9. TUF-BAR (The Concrete Reinforcement Specialist)

TUF-BAR has a clear and powerful focus: producing fiberglass rebar and tubing for concrete reinforcement. In an era where corrosion of steel rebar is a multi-billion dollar problem, TUF-BAR provides a compelling alternative. If your project involves concrete structures in corrosive environments (marinas, bridges, parking garages), they are a dedicated expert you should consult.

10. MFG Composites

MFG Composites offers a broad range of fiberglass products, including a wide selection of tubing. They are known for their competitive pricing and efficient service, making them a strong option for standard applications where budget is a primary concern without a complete compromise on quality.

How to Make Your Final Choice: A Buyer's Checklist

Now that you have the list, how do you narrow it down? Use this checklist:

Define Your Application: Is it structural, electrical, or cosmetic? What are the load, environmental, and temperature requirements?

Check for Certifications: Look for ISO 9001, ASTM test reports, or industry-specific certifications (e.g., UL, MIL-SPEC).

Evaluate Customization Capabilities: Do you need a custom size, color, or resin formulation? Not all manufacturers offer this.

Assess Technical Support: Can you speak to an engineer? A supplier that offers technical consultation is often more valuable than a slightly cheaper one that does not.

Consider Logistics & Scale: Does the manufacturer have the capacity for your order volume and can they ship to your location efficiently?

Request Samples: Any reputable manufacturer will provide samples for evaluation. Test them!
