UK Fiberglass Cable Tray Specifications

Fiberglass (FRP) cable trays in the UK are lightweight, corrosion-resistant, non-conductive systems available in ladder and channel types, designed to meet industrial load, fire, and safety standards. Types and ConfigurationsFRP cable trays are primarily available in two configurations: ladder-type and channel-type. Ladder-type trays consist of two longitudinal side rails connected by rungs, providing excellent ventilation and heat dissipation, suitable for multiple cable runs in industrial or chemical environments.

Channel-type trays have a perforated or solid bottom with integral side rails, often used in office buildings, hotels, or areas requiring fire, moisture, and dust protection. Both types can be fitted with flat or peaked covers for additional protection against environmental loads. Resin Systems and Material PropertiesUK FRP trays are typically manufactured using polyester or vinylester resin systems, providing high corrosion resistance, non-conductivity, and impact resistance.

Pultrusion technology ensures a resin-rich surface veil, enhancing UV protection and chemical resistance.

P trays are lightweight yet strong, often weighing one-third of equivalent steel trays while maintaining comparable load capacity. They are also non-magnetic and transparent to radio waves, making them suitable for sensitive electronic environments. Duty Ratings and DimensionsFRP trays are available in various duty ratings to suit installation requirements: Light Duty (SS): Tray depths 12–18mmMedium Duty (MRF): Tray depth 25mmHeavy Duty (SRF): Tray depth 50mmExtra Heavy Duty (XRF): Tray depth 80mm These trays are compatible with fast-fit systems like Swiftclip, which reduces installation time and simplifies handling.

Fire and Safety StandardsFRP cable trays in the UK are designed to meet ASTM E-84 Class 1 flame rating and ASTM D-635 self-extinguishing requirements, ensuring compliance with fire safety regulations.

C

E marking indicates conformity with European directives, which are transposed into UK law, and products may also be certified by third-party bodies for quality and safety. ApplicationsFRP cable trays are widely used in: Offshore platforms and oil & gas facilitiesChemical and metal refineriesWater treatment plantsCommercial and residential buildings requiring corrosion-resistant or non-conductive cable management Installation and AccessoriesUK FRP trays are supported by a range of fixings, brackets, and fittings designed for quick installation, including universal brackets that can be bent or hinged for complex layouts.

Covers, splice plates, and end caps are available to enhance safety and cable protection.

Summary

Fiberglass (FRP) cable trays in the UK provide a durable, lightweight, and corrosion-resistant solution for cable management across industrial, commercial, and residential applications. They are available in ladder and channel types, multiple duty ratings, and resin systems, with compliance to fire and safety standards, making them suitable for harsh and sensitive environments.
