As a leading manufacturer from Hengshui Ruibin New Materials LLC (established 2019, factory size 1,000–3,000 m², and annual export value US$2.5M–US$5M), we are proud to present our Fiberglass Pultruded Profiles with a guaranteed flexural modulus of 35 GPa. These profiles are specifically engineered for truss structures and meet stringent standard requirements, offering a lightweight yet robust alternative to traditional steel. Whether you are constructing support frames, bridges, or industrial platforms, our profiles deliver exceptional stiffness, corrosion resistance, and long-term durability.
Our fiberglass pultruded profiles are manufactured using continuous pultrusion technology, ensuring consistent cross-section and mechanical properties throughout the entire length. The 35 GPa flexural modulus means high load-bearing capacity with minimal deflection, making them ideal for trusses where structural stability is critical. Below is a detailed breakdown of the product’s key characteristics.
Key Features & Specifications
- Flexural Modulus: 35 GPa (±5%) – ensures excellent rigidity under load.
- Material Composition: High-strength E-glass fibers with vinyl ester or polyester resin, offering superior corrosion resistance.
- Standard Compliance: Designed and tested to meet common international structural standards (detailed reports available upon request).
- Weight Reduction: Approximately 70% lighter than equivalent steel profiles, reducing transportation and installation costs.
- Customizable Shapes: Available in I-beams, channels, angles, tubes, and flat bars to fit your truss design.
- UV & Weather Resistance: Optional UV-stabilized coatings extend service life in outdoor environments.
- Non-Conductive & Non-Magnetic: Ideal for sensitive applications like electrical substations or MRI rooms.

Benefits for Truss Applications
When used in truss structures, these profiles offer several distinct advantages:
- High Stiffness-to-Weight Ratio: The 35 GPa modulus ensures minimal sagging and deflection, critical for long-span trusses.
- Corrosion-Free: Unlike steel, fiberglass does not rust, eliminating maintenance and replacement costs in harsh environments (e.g., chemical plants, coastal areas).
- Easy Fabrication: Profiles can be cut, drilled, and assembled with standard tools. No need for heavy welding equipment.
- Thermal Insulation: Low thermal conductivity reduces heat transfer, improving energy efficiency in building applications.
- Design Flexibility: Custom cross-sections and lengths allow you to optimize the truss geometry for maximum strength and minimal material usage.
Our profiles have been successfully used in various projects including industrial platform trusses, pedestrian bridges, solar panel support structures, and conveyor systems. Customers appreciate the consistency of our pultrusion process and the strict quality control measures we implement from raw material inspection to final dimension verification.

Frequently Asked Questions (FAQ)
Q1: Can these profiles be used for outdoor trusses exposed to sunlight?
A: Yes, we offer an optional UV-resistant coating that extends the service life in direct sunlight. Please specify your outdoor application during inquiry.
Q2: What is the maximum length available per profile?
A: Standard lengths are up to 12 meters. Longer lengths up to 18 meters can be produced upon request, subject to transport restrictions.
Q3: Do you provide load‑bearing calculations for truss design?
A: Yes, we can supply typical mechanical property data for structural analysis. For custom designs, we recommend working with a structural engineer.
Q4: How does the 35 GPa flexural modulus compare to steel?
A: Steel has a modulus around 200 GPa, but fiberglass is 70% lighter. For trusses where weight is critical, the specific stiffness (modulus/density) of our profiles is competitive.
Q5: Can I get a sample before placing a bulk order?
A: Absolutely. We offer small sample pieces at a nominal cost (refundable with large orders). Contact us for details.
Q6: Are there any certifications your factory holds?
A: Our products are manufactured under strict quality control meeting common industry standards. Specific third-party certifications can be arranged upon request.
Q7: What is the typical lead time?
A: For standard profiles, 15–20 working days after order confirmation. Custom molds may add 5–10 days.
Q8: Do you offer fire‑retardant versions?
A: Yes, we can produce profiles with a self-extinguishing resin system that meets Class 1 fire rating (ASTM E84). Please indicate your fire safety requirements.
