FRP Trough-Type Cable Tray
FRP cable trays—also known as fiberglass cable trays or corrosion-resistant cable raceways—are manufactured through a pultrusion process utilizing fiberglass and resin. They are specifically designed for the laying, protection, and routing of power and communication cables.
FRP cable trays are primarily manufactured by blending, forming, molding, and curing a composite mixture consisting of magnesium oxide powder, fiberglass, inorganic resins, and various modifiers.

Their key features include:
1. Aesthetic Appearance, Lightweight, and High Mechanical Strength: They feature an attractive appearance, are lightweight, and possess high mechanical strength, serving as a complete replacement for traditional sheet metal or concrete cable trays.
2. Excellent Weather Resistance: They exhibit superior resistance to varying weather conditions and are suitable for temperatures ranging from -40°C to +70°C. This adaptability meets the diverse environmental requirements of my country—a country characterized by its vast territory and significant regional variations in temperature, humidity, and altitude.
3. Exceptional Anti-Aging Properties: By incorporating inorganic materials and modifiers, these inorganic FRP cable trays demonstrate outstanding resistance to aging. They possess strong resistance to water, acids and alkalis of standard concentrations, as well as various oils and solvents, thereby significantly extending their service life.
4. Advanced Manufacturing and High-Quality Materials: Utilizing advanced manufacturing techniques and premium raw materials, the production process fundamentally eliminates common defects associated with inorganic materials—such as moisture absorption, salt efflorescence, deformation, and warping—resulting in a product with superior strength and performance.
5. Superior Flame Retardancy: A standout feature of inorganic FRP is its exceptional flame-retardant capability. Due to the use of stable inorganic materials, the product has been tested and certified to meet the national Class A fire protection standard, making it an ideal solution for preventing and containing cable fires.
Advantages of FRP Cable Trays:
1. Lightweight yet High-Strength: With a specific gravity (density) of only one-quarter that of steel cable trays, they are lightweight yet robust. They also feature excellent corrosion resistance, anti-aging properties, thermal insulation, non-conductivity, and anti-static capabilities.
2. Vibration Damping and Noise Reduction: They effectively dampen vibrations and reduce noise levels.
3. Non-Toxic and Pollution-Free: The materials used are non-toxic and environmentally friendly, ensuring no pollution.
4. Heat-Resistant and Flame-Retardant: They withstand high temperatures and effectively resist combustion.
5. Long Service Life: They offer an extended operational lifespan and possess characteristics such as resistance to deformation, cracking, moisture absorption, and salt efflorescence, along with excellent dimensional stability.
6. Moderate Cost: They offer a cost-effective solution with a reasonable price point. 7. It consists of interlocking upper and lower sections; these sections are interchangeable, can be used independently, and can serve as flame-retardant cable trays.
8. Connecting fittings—such as horizontal bends, horizontal tees, and horizontal crosses—can be manufactured according to user specifications.
9. The width and height dimensions are determined based on user requirements or designed to match specific cable tray specifications.
10. It enjoys widespread application due to its advantages, including flexible power distribution, ease of installation, and low cost.
