Specifications of Fiberglass Cable Trays and Brackets

Fiberglass cable trays and brackets offer high corrosion resistance, lightweight strength, non-conductivity, and versatile design for industrial and harsh environments.

Material and Structural Advantages

Fiberglass cable trays are made from fiber-reinforced polyester (FRP) or vinyl ester resin, providing excellent corrosion resistance, long service life, and low maintenance compared to steel or aluminum trays. The composite material combines resin, glass fiber, and auxiliary materials, resulting in high tensile strength (300–500 MPa) while remaining lightweight, with a specific gravity of 1. 4–2.

P trays are non-conductive, reducing the need for grounding and enhancing safety in electrical installations.

Types of Fiberglass Cable Trays

Ladder Type: Features two side rails connected by transverse rungs, allowing excellent ventilation and heat dissipation, ideal for power cables and large-diameter control cables. Easy to install and modify for cable additions or removals.

Trough/

Channel Type: Has a bottom plate with side rails, offering moderate protection while maintaining some ventilation. Suitable for control, communication, and instrumentation cables, often with optional covers for outdoor or dusty environments. Solid Bottom Type: Fully enclosed with continuous side walls, providing maximum protection against dust, liquids, and mechanical damage.

Modular/

Cope Trays: Interlocking components allow fast assembly and reconfiguration, ideal for dynamic industrial systems or data centers.

Brackets and Support Features

Fiberglass cable trays are complemented by specialized brackets and fittings that ensure compact, stable, and flexible installation in various configurations. Common support types include universal supports, which are adjustable and compatible with multiple tray sizes, enabling easy installation in industrial and commercial settings. Brackets are designed to maintain structural integrity while accommodating different load classes and environmental conditions.

Performance Benefits

Corrosion and Chemical Resistance: FRP trays withstand acids, alkalis, salts, and organic solvents, making them suitable for offshore platforms, chemical plants, and wastewater treatment facilities. Lightweight and High Strength: Easier to transport, install, and maintain compared to steel, with a high strength-to-weight ratio. Durability and Longevity: Resistant to UV exposure, aging, and mechanical impact, ensuring long-term performance in harsh environments.

Design Flexibility: Can be molded or pultruded into complex shapes, supporting custom layouts and large-scale installations.

Applications

Fiberglass cable trays and brackets are widely used in industrial plants, substations, offshore platforms, chemical and oil refineries, and water treatment plants, where corrosion resistance, safety, and structural reliability are critical. They are suitable for power, control, communication, and instrumentation cables, providing organized, ventilated, and protected pathways for electrical infrastructure.
