Fiberglass Cable Tray Models and Specifications

Fiberglass cable trays, also known as FRP or GRP trays, are corrosion-resistant, lightweight, and non-conductive systems available in ladder, trough, and channel models, designed for harsh industrial and marine environments. Types of Fiberglass Cable Trays1.

Ladder Type

Consists of two side rails connected by transverse rungs. Open design allows excellent ventilation and heat dissipation, ideal for power cables and large-diameter control cables. Commonly used in power distribution, substations, and industrial plants.

Available in light, medium, and heavy-duty load classes with varying rung spacing for flexibility in installation and cable management. 2.

Trough or Channel Type

Features a bottom plate with side rails, providing more protection while allowing some ventilation. Suitable for control, communication, and instrumentation cables that require shielding from dust or falling objects. Often used in computer networks, sensitive signal circuits, and industrial control systems.

3.

Enduro/

Marine Rung Type

Designed for extreme corrosive and marine environments, including offshore platforms and chemical plants. Provides a 2-inch cable support surface and allows stainless steel banding for compliance with marine safety standards.

Material and Resin Specifications

Material: Pultruded Fiber Reinforced Polymer (FRP) or Glass-Reinforced Polymer (GRP). Resin Types: Isophthalic Polyester (IP): Good UV and weather resistance, commonly used in ICMS trays. Other resins may be available depending on project requirements.

Properties: Corrosion-resistant against chemicals and harsh environments. Impact-resistant, returning to original shape without permanent deformation. Non-conductive, reducing electrical hazards.

UV-resistant for outdoor exposure. Fire-retardant in accordance with ASTM E-84 standards. Standards and ComplianceNEMA FG1: Standard for fiberglass cable tray systems.

BS E

N 61537: 2007: European standard for cable tray systems.

NEM

A VE-2: Guidelines for fiberglass electrical support systems.

AB

S Approval: For marine applications, ensuring compliance with vessel safety requirements.

Installation and Performance Features

Lightweight: Approximately four times lighter than steel, simplifying installation. Easy to install: No welding required; can be cut and drilled on-site. Durable: Long service life with low maintenance costs.

Versatile fittings: Includes straight sections, bends, tees, reducers, and covers for complex routing. Strength-to-weight ratio: Comparable to steel while significantly lighter, enhancing structural efficiency.

Applications

Industrial plants: Chemical, oil, and metal refineries. Marine and offshore platforms: Resistant to saltwater and harsh conditions. Water treatment and power plants: For both power and instrumentation cables.

Sensitive electronics: Communication and control systems requiring protection from environmental hazards. Fiberglass cable trays provide a robust, lightweight, and corrosion-resistant solution for cable management in demanding environments, with multiple models and resin options to suit specific project requirements.
