Welcome to Hengshui Ruibin New Materials LLC, a professional manufacturer established in 2019 with a 1,000-3,000 square meter factory and a team of 101-200 experienced employees. With an annual export value of US$2.5 Million – US$5 Million, we specialize in high-performance FRP products. Our Black FRP Rectangular Tube UV Stabilized, 40% Glass Fiber Content for Enhanced Mechanical Strength is engineered to deliver exceptional durability and reliability for demanding environments. This product embodies our commitment to quality, innovation, and customer satisfaction, making it the ideal choice for structural applications that require both strength and weather resistance.
This rectangular tube is manufactured using a pultrusion process with a carefully formulated resin system that includes UV stabilizers. The 40% glass fiber content significantly enhances its mechanical properties, providing superior tensile, flexural, and impact strength compared to standard FRP profiles. The black color not only offers a sleek appearance but also helps in heat dissipation and reduces visible dirt accumulation. Whether you need support beams, handrails, or framing components, this product meets the highest standards of performance and longevity.
Key Features & Benefits
- UV Stabilized: Built-in UV inhibitors prevent degradation from sunlight, ensuring long life in outdoor applications.
- 40% Glass Fiber Content: Delivers enhanced mechanical strength – higher tensile and flexural modulus compared to standard FRP tubes.
- Lightweight & High Strength: Approximately 75% lighter than steel with comparable or better strength-to-weight ratio, reducing installation costs.
- Corrosion Resistant: Impervious to moisture, chemicals, salt spray, and rust – ideal for harsh environments like marine, chemical plants, and wastewater treatment.
- Non-Conductive & Non-Magnetic: Safe for electrical applications and environments where magnetic interference must be avoided.
- Low Thermal Conductivity: Helps maintain temperature stability, reducing energy loss in structural applications.
- Easy to Fabricate: Can be cut, drilled, and assembled with standard tools; no special equipment required.
- Customizable Dimensions: Available in various lengths, wall thicknesses, and cross-section sizes to meet project specifications.

Frequently Asked Questions (FAQ)
1. Can this black FRP rectangular tube be used outdoors in direct sunlight?
Yes, the tube contains UV stabilizers that protect against long-term sun exposure. It is designed to maintain its mechanical properties and appearance even under harsh UV radiation.
2. What is the maximum length you can produce?
Standard lengths are 6 meters (20 ft), but we can produce custom lengths up to 12 meters upon request. Please contact us with your specific requirements.
3. Is this product fire resistant?
Our standard formulation offers good self-extinguishing properties. For applications requiring specific fire ratings (e.g., UL 94 V-0), we can incorporate flame-retardant additives as an option.
4. Can I drill or cut this tube without causing damage?
Absolutely. FRP is easily machinable with standard carbide-tipped tools. We recommend using proper dust control measures. The material does not crack or splinter easily.
5. Is the black color only cosmetic, or does it have functional benefits?
Black color not only provides a uniform appearance but also helps reduce surface temperature in sunlight due to better heat radiation. It also hides minor scratches and dirt.
6. Do you offer samples before bulk order?
Yes, we provide free samples of standard sizes. You only need to cover the shipping cost. Samples are typically sent within 3-5 working days.
7. What is the minimum order quantity (MOQ)?
For stock sizes, MOQ is 100 meters. For custom dimensions or special resin, MOQ may vary. Please discuss with our sales team.
8. How long does shipping take to North America or Europe?
Typical shipping time from Tianjin or Qingdao ports is 25-35 days by sea, depending on the destination. Express shipping (air freight) is also available for urgent orders.
