Fibre Reinforced Plastic (FRP) Cable Trays in the United Kingdom: A Complete Guide 2026

In modern infrastructure, managing electrical cables efficiently is as important as the cables themselves. One material that has increasingly gained attention for cable management in the UK is Fibre Reinforced Plastic (FRP), also known as Glass Reinforced Plastic (GRP). Lightweight, durable, and corrosion-resistant, FRP cable trays are transforming how industries handle electrical cabling in challenging environments.

What Are FRP Cable Trays?

FRP cable trays are made from plastic reinforced with fibers, typically glass, to provide strength and stability. Unlike traditional metal trays, FRP trays are non-conductive, resistant to corrosion, and lighter, making them ideal for environments where metal trays would degrade quickly or pose safety risks.

These trays are widely used across industries such as:

• Chemical and petrochemical plants
• Marine and offshore facilities
• Railways and transportation systems
• Wastewater treatment plants
• Coastal infrastructure

The versatility of FRP makes it suitable for both indoor and outdoor applications, especially in locations prone to moisture, salt, or chemical exposure.

Advantages of Using FRP Cable Trays

Corrosion Resistance FRP trays do not rust or corrode, which dramatically increases their lifespan in harsh environments. This is especially important in coastal or chemical-heavy locations common across the UK.

Lightweight Compared to steel or aluminum trays, FRP trays are significantly lighter, which simplifies transportation and installation.

Non-Conductive Being non-metallic, FRP trays offer electrical insulation, reducing the need for additional grounding measures and improving overall safety.

Durability FRP trays can withstand extreme temperatures, UV exposure, and chemical contact, providing long-term reliability in industrial settings.

Low Maintenance Unlike metal trays that may require periodic painting or rust prevention, FRP trays require minimal upkeep, reducing maintenance costs.

Considerations When Choosing FRP Cable Trays

While FRP trays have many benefits, proper selection is crucial:

Resin Type: Different resins offer varying resistance to heat, chemicals, and fire. Polyester is common for general use, while vinyl ester is used for highly corrosive environments.

Load Capacity: FRP trays have unique load and span characteristics. It’s essential to consider the weight of cables and the distance between supports.

Fire Performance: Some resins have higher fire resistance than others, which is critical in public and industrial facilities.

Thermal Expansion: FRP expands and contracts more than metal under temperature changes. Proper design should account for this to avoid stress or warping.

Support and Fixings: Use compatible supports and brackets to maximize strength and longevity.

Applications in the UK

FRP cable trays are especially popular in the UK due to the country’s wet climate, industrial activity, and coastal regions. Industries such as rail, ports, and chemical processing plants benefit from FRP trays’ corrosion resistance and safety features. Their lightweight nature also reduces labor costs during installation in large-scale projects.

FRP Tray Types

FRP cable trays come in different forms to suit various applications:

• Ladder Tray: Ideal for heavy-duty cables, providing ventilation and ease of cable installation.
• Perforated Tray: Allows airflow and drainage, preventing moisture buildup.
• Solid Bottom Tray: Provides maximum protection for sensitive cables against dust, dirt, and debris.
