Hengshui Ruibin New Materials LLC, a professional FRP manufacturer established in 2019, proudly offers the Lightweight FRP round tube 80mm OD 6mm wall 30MPa flexural strength for load-bearing frames. This tube combines low weight with reliable structural performance, making it an ideal choice for engineers and fabricators who demand strength without the burden of traditional steel. Our factory, spanning 1,000–3,000 square meters and powered by 101–200 experienced employees, uses advanced pultrusion technology to ensure consistent quality in every batch. Whether you are building frames, supports, or lightweight structures, this FRP tube delivers a corrosion-resistant and cost-effective solution.
Key Features & Technical Specifications
- Lightweight yet strong: The tube has a density far lower than steel, reducing overall structure weight while maintaining a flexural strength of 30MPa.
- Excellent corrosion resistance: Impervious to moisture, chemicals, and UV degradation, suitable for outdoor and harsh environments.
- Non-conductive and non-magnetic: Safe for electrical enclosures, antenna support, and applications where electrical insulation is required.
- Dimensional stability: Precision-manufactured outer diameter of 80mm and wall thickness of 6mm provide uniform cross-section and reliable fit.
- Easy handling and installation: Can be cut, drilled, and machined with standard tools, saving labor time on site.

Why Choose Our FRP Round Tube?
This product is engineered for versatility and long service life. Unlike steel, it will not rust or corrode, eliminating frequent maintenance. Its high strength-to-weight ratio makes it easier to transport and install, reducing overall project costs. The tube is also an excellent electrical insulator and has low thermal conductivity, which proves valuable in many industrial applications.
- For load-bearing frames: Suitable for trusses, propping frames, machine guards, and support columns.
- For infrastructure: Used in bridges, walkways, and railing systems where corrosion-resistance is critical.
- For transportation: Ideal for lightweight cargo systems and vehicle accessories.
- For renewable energy: Works well in solar panel mounting frames and wind turbine components.

Frequently Asked Questions (FAQ)
Q: Can this tube be used outdoors for a long time?
A: Yes. The FRP material is inherently resistant to moisture, salt, and UV radiation. It does not rot or rust, making it suitable for decades of outdoor service.
Q: What is the maximum length you can supply?
A: Standard lengths are 6 meters and 12 meters. We can also cut custom lengths based on your drawings or as requested for freight optimization.
Q: How does the flexural strength of 30MPa compare to steel?
A: Steel has a higher flexural strength, but FRP is much lighter and offers corrosion resistance. For many non-heavy-duty load-bearing frames, 30MPa provides excellent performance while cutting weight by up to 70% compared to steel.
Q: Can this tube be drilled, cut, or machined easily?
A: Yes. Standard carbide tools work fine. We recommend using proper dust control and eye protection when cutting FRP.
Q: Do you provide samples before bulk ordering?
A: Yes. We can send samples by express courier. Sample cost is usually refundable or deductible from the first order.
Q: Is the tube electrically conductive?
A: No. FRP is an excellent electrical insulator. It also has low thermal conductivity, which is beneficial in many electrical and thermal applications.
Q: Can you customize the color or surface finish?
A: Absolutely. We offer a range of colors (black, grey, yellow, etc.) and surface textures, including sand-coated for improved bonding. These options are customizable upon request.
Q: What packaging do you use for export?
A: Tubes are bundled, wrapped with protective film, and secured in wooden or cardboard pallets to prevent damage during transit. Custom packaging is also available.
As a manufacturer with strong exporting experience and a dedicated team, we guarantee consistent product quality and responsive after-sales support.
