Hengshui Ruibin New Materials LLC, a professional manufacturer established in 2019, proudly offers our non-conductive FRP pultruded profiles specifically engineered for paper mill structural supports. These profiles are manufactured using premium fiberglass reinforcement and UV-stabilized resin, delivering outstanding corrosion resistance, electrical non-conductivity, and long-lasting dimensional stability in harsh industrial environments. With our factory located in Hengshui, Hebei, we combine advanced pultrusion technology with a dedicated team of 101–200 employees to produce structural profiles that meet the demanding needs of paper mills worldwide.
Our FRP pultruded profiles are created through a continuous pultrusion process that embeds continuous glass fibers in a UV-stabilized polymer matrix. The result is a high-strength, lightweight alternative to traditional steel or aluminum structural supports that suffers no corrosion from the moisture, chemicals, and paper pulp residues common in paper manufacturing facilities. The non-conductive nature of these profiles makes them particularly suitable for areas where electrical insulation is required, while the UV-stabilized resin prevents degradation from sunlight exposure, ensuring reliable performance in both indoor and outdoor installations.
Below we present the key features and benefits of our non-conductive FRP pultruded profiles:
- Non-conductive material: Provides inherent electrical insulation, enhancing worker safety and preventing accidental electrical shorts in mill environments.
- UV-stabilized resin: Withstands prolonged sunlight exposure without chalking, cracking, or loss of mechanical strength, ideal for outdoor support structures.
- Excellent corrosion resistance: Impervious to moisture, acids, alkalis, and organic solvents, eliminating the need for periodic painting or galvanizing.
- High strength-to-weight ratio: Substantially lighter than steel, simplifying handling, transportation, and installation while retaining comparable structural capacity.
- Low maintenance: Does not rust, rot, or splinter, reducing lifecycle costs and downtime associated with maintenance of conventional supports.
- Dimensional stability: Low thermal expansion and minimal creep ensure tight tolerances and reliable alignment of conveying systems, walkways, and equipment supports.
- Customizable profiles: Available in a variety of standard and custom shapes, including angles, channels, I-beams, and round or square tubes, cut to required lengths.
- Chemical and moisture resistance: Ideal for areas with high humidity, washdowns, and exposure to bleaching agents or sizing chemicals.
To better assist your material selection, we provide the following typical technical specifications for our standard FRP pultruded profiles. Note that exact values may vary depending on the shape, wall thickness, and glass content.
| Property | Typical Value |
|---|---|
| Glass content | 60% – 70% by weight |
| Density | 1.8 – 2.1 g/cm³ |
| Tensile strength | 300 – 450 MPa |
| Flexural strength | 350 – 500 MPa |
| Compressive strength | 250 – 400 MPa |
| Dielectric strength | Optional, available upon request |
| Thermal conductivity | Low, non-conductive |
| UV resistance | Excellent, UV-stabilized resin |
| Operating temperature | -40°C to +80°C (continuous) |
| Surface resistivity | High (non-conductive) |
Our FRP pultruded profiles are designed for a wide range of paper mill structural applications, including:
- Support frames for paper machine hoods and drying sections
- Walkways, platforms, and ladder systems in wet areas
- Cable tray supports and electrical equipment enclosures where non-conductivity is required
- Structural components for chemical storage areas and effluent treatment facilities
- Guards, covers, and brackets exposed to corrosive chemicals or constant humidity
- Replacement of steel and wood supports prone to rust and decay
Choosing our FRP profiles brings immediate operational benefits. The reduced weight allows for faster installation without heavy lifting equipment, lowering labor costs and improving safety on site. Their corrosion resistance means fewer replacements and less downtime, which is critical for continuous paper production processes. Moreover, the non-conductive property eliminates the need for additional insulation measures, simplifying design and reducing material costs.

Frequently Asked Questions
Q1: What makes these FRP profiles non-conductive?
A: The combination of glass fibers and polymer resin provides excellent electrical insulation. Our standard profiles are tested for dielectric strength without any conductive fillers, ensuring safe use in electrical proximity.
Q2: Are these profiles suitable for outdoor installation?
A: Yes, the UV-stabilized resin is specifically formulated to resist solar radiation, preventing surface degradation and color fading. This makes them durable for open structures, roof supports, and exterior walkways.
Q3: Can you produce custom shapes and dimensions?
A: Absolutely. We offer custom pultruded profiles including special cross-sections, unusual widths, and any required length. Send us a drawing or sketch, and our engineers will provide a feasibility evaluation and tooling plan.
Q4: How do these profiles compare to steel in terms of load bearing?
A: While FRP has a lower elastic modulus than steel, it can be engineered with adequate wall thickness and glass content to match the required structural strength. For many paper mill applications, strength and corrosion resistance combined make FRP the preferred option.
Q5: What is the lead time for standard and custom products?
A: Standard profiles are typically shipped within 15–20 days after order confirmation. Custom profiles may require an additional 10–15 days for mold production, depending on complexity.
Q6: Do you provide installation guidance?
A: Yes, we provide technical data sheets, installation recommendations, and accessory options such as FRP fasteners and brackets. Our support team is responsive to technical inquiries.
Q7: Are there any certifications for these products?
A: Our products are manufactured under strict internal quality control. Specific certifications can be arranged upon request; please contact us to discuss the standards required for your market.
Q8: What is the minimum order quantity?
A: For standard profiles, the MOQ is generally 300 meters. For custom profiles, the MOQ depends on the mold cost and material requirement, which our sales team will confirm with you.
