Welcome to Hengshui Ruibin New Materials LLC, a professional manufacturer established in 2019 with a factory covering 1,000–3,000 square meters and an annual export value of US$2.5–5 million. Our team of 101–200 skilled employees is dedicated to producing high-quality composite solutions for global markets including North America, South America, Europe, Asia, Africa, and Oceania. We are proud to introduce our Heavy Duty Pultruded Fiberglass Profiles – engineered to support a load capacity of 500 kg/m while achieving a Fire Rating Class 1 (per ASTM E84). The durable black finish ensures long-lasting performance in harsh environments. These profiles combine exceptional strength, lightweight construction, and superior fire resistance, making them an ideal choice for demanding structural applications.
Our pultruded fiberglass profiles are manufactured using a continuous pultrusion process that delivers consistent cross-sections and high fiber volume. The result is a material that outperforms traditional steel or aluminum in many aspects – corrosion-free, non-conductive, low maintenance, and significantly lighter. The black finish is UV-stable and can be further customized with a gel coat or paint for enhanced aesthetics or additional protection. Whether you need beams, channels, tubes, or custom shapes, we can tailor the dimensions to meet your project requirements.
Key Features & Technical Specifications
- High Load Capacity: 500 kg/m (linear) – suitable for heavy-duty platforms, bridges, and industrial supports.
- Fire Rating Class 1: Meets ASTM E84 Class 1 (flame spread index ≤25, smoke developed index ≤450), providing excellent fire safety.
- Corrosion Resistance: Inherently resistant to chemicals, moisture, salt, and UV degradation – ideal for marine, wastewater, and chemical plants.
- Lightweight: Only 20–30% the weight of steel, reducing transportation and installation costs.
- Electrical & Thermal Insulation: Non-conductive and low thermal conductivity, perfect for electrical substations or energy installations.
- Low Maintenance: No painting, coating, or rust-proofing required; saves long-term operational costs.
- Customizable: Available in various lengths (up to 12 meters), widths, thicknesses, and shapes (I-beams, U-channels, square tubes, angles, etc.).

Why Choose Our Heavy Duty Pultruded Fiberglass Profiles?
Compared to traditional materials such as steel or aluminum, our fiberglass profiles offer a longer service life in corrosive environments, eliminate the need for secondary coatings, and reduce structural dead weight. The black finish not only provides a sleek appearance but also offers enhanced UV resistance for outdoor installations. With a load capacity of 500 kg/m, these profiles can replace steel beams in many industrial applications while delivering significant cost savings over the lifecycle.
Benefits for your projects:
- Faster installation: lightweight profiles can be handled with smaller crews and lighter equipment.
- Reduced maintenance costs: no rust, no rot, no painting – ideal for offshore, chemical, or food processing plants.
- Improved safety: non-conductive and fire-resistant Class 1 material protects personnel and assets.
- Design flexibility: custom shapes and sizes are available; our engineering team can assist with structural calculations.
- Environmentally friendly: pultruded composites have a long lifespan and are fully recyclable in specialized facilities.

Frequently Asked Questions (FAQ)
-
Q: What does “load capacity 500 kg/m” mean exactly?
A: It means the profile can support a uniformly distributed load of 500 kilograms per linear meter when properly supported. Actual capacity depends on span length, cross-section geometry, and support conditions. Our engineers can provide detailed load tables for your specific profile. -
Q: Is the black finish only aesthetic, or does it have functional benefits?
A: The black finish serves both purposes. It provides a uniform, professional appearance while offering enhanced UV resistance and weatherability. The surface can be further treated with a gel coat for additional chemical resistance if needed. -
Q: Can these profiles be used outdoors in extreme temperatures?
A: Yes. Fiberglass composites maintain structural integrity from -40°C to +80°C (continuous). For higher temperatures, special resin formulations are available upon request. The low coefficient of thermal expansion ensures stability in varying climates. -
Q: Do you provide custom lengths or non-standard shapes?
A: Absolutely. We can cut profiles to any length up to 12 meters and manufacture custom cross-sections (e.g., hollow rectangles, complex channels) with tooling charges. Lead times vary based on complexity. -
Q: What is the typical lead time for standard profiles?
A: For standard sizes (e.g., I-beams, channels) with black finish, lead time is approximately 15–25 working days after order confirmation, depending on quantity. Custom shapes may take 30–40 working days. -
Q: Are these profiles compatible with standard fasteners and brackets?
A> Yes. They can be drilled, cut, and machined on-site using standard woodworking tools. We recommend using stainless steel or composite fasteners to avoid galvanic corrosion. -
Q: Do you offer any warranty or quality guarantee?
A: We provide a 12-month warranty against manufacturing defects. All profiles are tested for mechanical properties before shipment. Please contact our sales team for detailed warranty terms. -
Q: How do I determine the right profile size for my application?
A: Our technical support team can help with structural calculations. Provide us with span, load requirements, and environmental conditions, and we will recommend the optimal profile size and shape.
