Welcome to Hengshui Ruibin New Materials LLC — a dedicated manufacturer of high-performance fiberglass profiles since 2019. Our Fiberglass Rectangular Tube is specifically engineered for cable tray systems, offering exceptional UV stabilization and a lightweight structure that simplifies installation. With a standard length of 3 meters, this product combines durability with ease of handling, making it a preferred choice for industrial, commercial, and infrastructure projects worldwide.
As a factory with 1,000–3,000 square meters of production space and 101–200 skilled employees, we ensure consistent quality and timely delivery. Our annual export value of US$2.5–5 million reflects the trust of clients across North America, South America, Europe, Asia, Africa, and Oceania. This rectangular tube is produced using advanced pultrusion technology, providing excellent mechanical strength, corrosion resistance, and long service life — all while remaining environmentally friendly.
In cable tray systems, the tube serves as a structural support for cables, offering superior electrical insulation and non-conductive properties. Its UV-stabilized formulation prevents degradation from sunlight exposure, making it suitable for both indoor and outdoor installations. Let’s explore the key features and benefits in detail.
Key Features & Technical Specifications
- UV Stabilized: Special additives protect against ultraviolet radiation, ensuring color retention and structural integrity even in harsh sunlight.
- Lightweight Design: Approximately 70% lighter than steel equivalents, reducing transportation costs and easing manual handling.
- High Strength-to-Weight Ratio: Fiberglass reinforcement delivers tensile strength comparable to steel but with significant weight savings.
- Corrosion & Chemical Resistance: Impervious to moisture, chemicals, and salt spray — ideal for marine, wastewater, and chemical plants.
- Non-Conductive & Non-Magnetic: Safe for electrical environments; no eddy currents or interference with sensitive electronics.
- Flame Retardant: Self-extinguishing properties meet industry fire safety standards (optional upon request).
- Customizable Dimensions: Available in various rectangular cross-sections (width × height) and wall thicknesses to suit specific loading requirements.
- Smooth Surface: Low coefficient of friction for easy cable pulling; can be textured for enhanced grip if needed.

Advantages for Cable Tray Applications
Cable tray systems demand reliable materials that can withstand mechanical loads, environmental exposure, and electrical demands. Our fiberglass tubes excel in these areas:
- Easy Installation: Lightweight sections allow workers to assemble longer spans without heavy lifting equipment, reducing labor costs and project timelines.
- Longevity: UV stabilization prevents yellowing and brittleness; the tube maintains its mechanical properties for decades even in outdoor environments.
- Cost Efficiency: Lower shipping weight means cheaper freight; no need for painting or galvanizing, saving maintenance expenses.
- Safety: Non-conductive and flame-retardant properties minimize electrical hazards and fire risks in cable management systems.
- Adaptability: Can be cut, drilled, and joined on-site using standard tools; compatible with metal or composite brackets and fittings.
FAQ – Frequently Asked Questions
-
What are the common dimensions of this fiberglass rectangular tube?
Standard sizes range from 50×30 mm to 100×50 mm with wall thickness from 2 to 5 mm. Custom dimensions are available — please contact our sales team for a quote. -
Can this tube be used outdoors in direct sunlight?
Yes, the product is UV stabilized to resist degradation from sunlight. It has passed accelerated weathering tests equivalent to over 2000 hours of UV exposure. -
Is the tube resistant to chemicals?
Yes, fiberglass resin systems used offer excellent resistance to most acids, alkalis, solvents, and salt water. We recommend confirming compatibility with specific chemicals before ordering. -
How do I connect multiple sections together?
Sections can be joined using internal or external splice kits, adhesive bonding, or stainless steel fasteners. We can provide assembly recommendations for your specific design. -
What is the maximum span length when used in a cable tray?
Span depends on tube size, wall thickness, cable load, and support spacing. Typically, a 50×30×3 mm tube can support up to 50 kg/m over a 2 m span. Contact us for load tables. -
Is the product fire retardant?
Standard formulation meets self-extinguishing requirements (UL 94 HB). A flame-retardant version achieving UL 94 V-0 is available as an option. -
Can I order a sample before mass production?
Yes, we provide sample pieces (cut to 300 mm or 1 m) at a nominal cost. The sample cost is deductible from your first bulk order. -
What is the typical lead time for bulk orders?
For standard sizes and color, lead time is 15–20 working days after deposit. Custom orders require additional 7–10 days for tooling setup.
