Specifications of extruded fiberglass cable trays

Extruded fiberglass cable trays offer high corrosion resistance, lightweight strength, electrical insulation, and durability for harsh industrial environments.

Material and Construction

Extruded fiberglass cable trays are made from fiber-reinforced polymer (FRP) or fiberglass-reinforced plastic, often using pultrusion technology to create strong, uniform profiles . They are available in polyester or vinyl ester resin systems, providing excellent resistance to chemicals, moisture, UV exposure, and extreme temperatures . The pultrusion process ensures a resin-rich surface for superior corrosion protection and long-term durability .

Key Features

• Corrosion Resistance: Highly resistant to rust, chemical attack, and environmental degradation, making them ideal for offshore platforms, chemical plants, water treatment, and marine environments .
• Strength-to-Weight Ratio: Lightweight yet strong, often weighing one-third of steel trays while maintaining comparable or superior load capacity .
• Electrical Insulation: Non-conductive and non-magnetic, reducing shock hazards and interference with radio, radar, or microwave signals .
• Durability and Longevity: Resistant to physical wear, UV exposure, and extreme temperatures, ensuring long service life with minimal maintenance .
• Flame and Safety Compliance: Many trays meet ASTM E-84 Class 1 flame rating and ASTM D-635 self-extinguishing requirements .
• Low Maintenance: FRP trays do not require painting or rust protection, reducing lifecycle costs .

Types and Design Options

• Ladder Type: Open design with side rails and transverse rungs, allowing ventilation and heat dissipation, suitable for power cables and large-diameter control cables .
• Trough or Channel Type: Bottom plate with side rails, offering moderate protection while maintaining ventilation, ideal for control, communication, and instrumentation cables .
• Solid Bottom Type: Fully enclosed bottom and side walls for maximum protection against dust, liquids, and mechanical damage .
• Custom Profiles: Options like flange-in, flange-out, low-profile, or “Z” siderail designs allow installation in tight spaces or flush wall mountings .

Installation and Flexibility

Extruded fiberglass trays are easy to handle and install due to their lightweight nature, and they can be modified in the field to accommodate additional cables or changes in layout . Pre-drilled sections and modular components such as bends, tees, reducers, and covers enhance adaptability for complex industrial systems .

Applications

These trays are widely used in industrial, commercial, and infrastructure projects, including oil and gas facilities, chemical plants, refineries, water treatment plants, and offshore platforms, where corrosion resistance, electrical safety, and durability are critical . Extruded fiberglass cable trays provide a robust, cost-effective, and long-lasting solution for cable management in environments where traditional metal trays may fail.
