Hengshui Ruibin New Materials LLC, a dedicated manufacturer based in Hengshui, Hebei, China, brings you our premium Fire-Retardant Pultruded Fiberglass Profiles. With a precise density of 1.8 g/cm³ and a continuous use temperature rating of 150°C, these profiles are engineered for demanding environments where safety and durability are paramount. Since our establishment in 2019, we have focused on producing high-quality fiberglass composites that meet international standards, serving clients across North America, Europe, Asia, and beyond. Our 1,000–3,000 square meter factory and experienced team of 101–200 employees ensure consistent quality and reliable supply.
Product Overview
Our pultruded fiberglass profiles are manufactured using a continuous process that combines fiberglass reinforcements with a specially formulated fire-retardant resin system. The result is a lightweight yet strong material that offers excellent thermal stability, corrosion resistance, and structural integrity. These profiles are ideal for applications requiring non-conductivity, high strength-to-weight ratio, and compliance with fire safety regulations.
Key Features & Benefits
- Fire Retardant: Our proprietary resin system provides inherent flame resistance, reducing the spread of fire and meeting stringent safety requirements.
- High Density (1.8 g/cm³): Ensures excellent mechanical strength and stiffness, superior to standard fiberglass profiles.
- Continuous Use at 150°C: Maintains structural integrity and performance under prolonged heat exposure, making it suitable for hot environments.
- Corrosion Resistant: Impervious to moisture, chemicals, and UV radiation – ideal for outdoor and industrial settings.
- Electrical Insulation: Non-conductive and non-magnetic, perfect for electrical enclosures and platforms.
- Lightweight: Approximately 75% lighter than steel, reducing installation and transportation costs.
- Low Maintenance: Does not rust, rot, or require painting; long service life reduces replacement frequency.
- Custom Shapes & Sizes: We can produce rods, tubes, channels, angles, and custom profiles per your drawings.

Frequently Asked Questions
-
Q: What is the maximum length you can produce for these profiles?
A: Our pultrusion line can produce continuous lengths up to 12 meters as standard. Longer lengths are possible upon request with special handling arrangements. -
Q: Are these profiles UV resistant for outdoor use?
A: Yes, we can add UV inhibitors to the resin system to enhance outdoor durability. Please specify your requirement when ordering. -
Q: Can you produce non-standard shapes or hollow sections?
A: Absolutely. We have tooling capabilities for a wide range of cross-section profiles. Send us a drawing or sketch for a feasibility evaluation. -
Q: How does the fire-retardant property affect the mechanical strength?
A: Our formulation balances flame resistance with mechanical performance. The tensile strength remains above 300 MPa, comparable to standard fiberglass profiles. -
Q: What is the minimum order quantity (MOQ)?
A: For standard profiles, MOQ is 500 kg. For custom shapes, MOQ may vary depending on tooling complexity – contact our sales team for details. -
Q: Do you provide any testing certificates?
A: Yes, we can provide in-house test reports for density, temperature resistance, and flame spread. Third-party certifications (e.g., ASTM, UL) are available upon request at additional cost. -
Q: How long does a typical delivery take?
A: For standard profiles, delivery takes 15–20 working days after order confirmation. Custom orders may require 25–35 working days depending on mold fabrication time. -
Q: Can I get a sample before placing a bulk order?
A: Yes, we offer sample pieces (e.g., 30 cm length) for testing. Sample cost and shipping are negotiable. Please inquire for details.
