Hengshui Ruibin New Materials LLC, established in 2019 with a factory spanning over 1,000-3,000 square meters and a dedicated team of 101–200 employees, is a leading manufacturer specializing in high-performance composite profiles. Our annual export value of US$2.5 Million – US$5 Million reflects our commitment to serving global markets including North America, South America, Europe, Asia, Africa, and Oceania. We proudly present our Fire-Retardant FRP Pultruded Profiles Grade 2 with an impressive 300 MPa tensile strength and UV-resistant outdoor grade — a product engineered for demanding environments where safety, durability, and longevity are non-negotiable. Whether you need structural supports for solar farms, walkways in corrosive areas, or electrical insulation components, these profiles deliver consistent performance under extreme conditions.
Our FRP pultruded profiles are manufactured using a continuous pultrusion process that ensures uniform cross-sections, high fiber-to-resin ratio, and superior mechanical properties. The Grade 2 fire-retardant formulation meets stringent industry standards for flame spread and smoke generation, making them ideal for public infrastructure and enclosed spaces. With 300 MPa tensile strength, these profiles rival traditional steel in load-bearing capacity while weighing only about one-quarter of steel, reducing transportation and installation costs. The UV-resistant outdoor grade is specially formulated with stabilizers to prevent degradation from sunlight, ensuring decades of service life in direct sun exposure without cracking, fading, or loss of strength.
Key Features and Technical Specifications
| Property | Value | Benefit |
|---|---|---|
| Fire Retardant Grade | Grade 2 (Flame Spread Index ≤ 25) | Enhanced fire safety for buildings and tunnels |
| Tensile Strength | 300 MPa (minimum) | High load-bearing capacity with light weight |
| Density | 1.7 – 2.0 g/cm³ | 75% lighter than steel, easier handling |
| UV Resistance | Outdoor Grade (UV-stabilized) | No degradation from sun exposure for 20+ years |
| Service Temperature | -40°C to +80°C | Reliable performance in extreme climates |
| Corrosion Resistance | Excellent (acid, alkali, salt) | No rust, ideal for chemical plants and marine use |
| Electrical Insulation | Non-conductive | Safe for electrical enclosures and cable trays |
| Standard Length | 6 meters (custom lengths available) | Reduces waste and installation joints |
Product Advantages
- Superior Fire Safety: Grade 2 flame-retardant properties minimize fire spread, meeting the requirements of building codes and insurance standards for public facilities.
- High Mechanical Strength: 300 MPa tensile strength ensures reliable structural integrity even under heavy loads, suitable for load-bearing gratings, handrails, and bridge decks.
- Lightweight Construction: At just 25% of steel weight, these profiles reduce structural dead load, allowing lighter foundations and easier handling during installation — saving both time and labor costs.
- Weather Resistance: The UV-resistant formulation prevents yellowing, chalking, and embrittlement, maintaining appearance and performance for decades in outdoor environments.
- Non-Corrosive & Chemical Resistant: Ideal for wastewater treatment plants, chemical processing, and coastal projects where metal would quickly rust or corrode.
- Low Maintenance: Unlike wood or metal, FRP does not rot, splinter, or require painting. Simple cleaning with water restores its appearance.
- Customizable Profiles: We can produce various shapes (I-beam, channel, angle, tube, custom sections) and lengths to match your project specifications.

Frequently Asked Questions (FAQ)
Q1: What does “Grade 2” fire-retardant mean for FRP profiles?
A: Grade 2 indicates a flame spread index (FSI) typically ≤ 25 according to ASTM E84 or similar standards. This means the material resists ignition and limits flame propagation, making it suitable for applications requiring a moderate level of fire safety, such as exit pathways and utility tunnels.
Q2: Can these profiles be used in direct sunlight without degradation?
A: Yes. Our outdoor-grade profiles incorporate UV stabilizers (e.g., carbon black or benzotriazoles) that protect the resin matrix from UV radiation. They have been tested for long-term outdoor exposure and maintain at least 80% of original strength after 20 years of simulated sunlight.
Q3: Are custom shapes and sizes available?
A: Absolutely. We can manufacture profiles in custom cross-sectional shapes, lengths, and colors based on your drawings or specifications. Minimum order quantities may apply, but we are flexible for prototypes and small batches.
Q4: How does the tensile strength of 300 MPa compare to steel?
A: 300 MPa is comparable to certain grades of structural steel (e.g., A36 steel has about 250-400 MPa), but FRP is only one-quarter the weight. This means you get comparable strength with drastically reduced dead load, making it easier to transport and install.
Q5: What is the service life of these profiles in an outdoor coastal environment?
A: With proper installation and no mechanical damage, our UV-resistant FRP profiles can last 25–30 years in coastal or marine environments. They are completely immune to saltwater corrosion, unlike metals.
Q6: Can I drill or cut these profiles on-site?
A: Yes. FRP pultruded profiles can be cut, drilled, and machined using standard carbide-tipped tools. We recommend using dust collection and personal protective equipment due to glass fiber dust. Details are provided in our installation guide.
Q7: What are the typical lead times for large orders?
A: For standard shapes and 6-meter lengths, lead time is 15–20 working days after order confirmation and deposit. Custom profiles may require 25–30 working days. We ship from Tianjin or Qingdao ports, and expedited shipping is available upon request.
Q8: Do you provide third-party test reports or certifications?
A: Yes. We can provide test reports from accredited laboratories for fire retardancy, mechanical properties, and UV aging upon request. Our product certifications are available for review; please contact our sales team for details.
