Fireproof cable trays in the UK are available in various materials and fire-resistant designs, with prices depending on type, material, and supplier, typically ranging from £50 to £300+ per meter for specialized systems.

Types and Materials

Fireproof cable trays are designed to protect electrical cables from fire and maintain system integrity. Common types include:

• Steel and Stainless Steel Trays: Durable, corrosion-resistant, and suitable for high-temperature environments. Stainless steel options (304 or 316) offer long-term performance and fire resistance .
• PVC and UPVC Trays: Lightweight, impact-resistant, and inherently fire-resistant, suitable for indoor installations .
• GRP (Glass Reinforced Plastic) Trays: Lightweight, non-conductive, chemical and UV resistant, and fireproof. GRP trays are ideal for industrial environments and harsh conditions .
• Wire Mesh and Basket Trays: Provide ventilation and easy cable access while maintaining fire safety standards .

Fire Resistance Standards

In the UK, fireproof cable trays often comply with stringent standards such as:

• DIN 4102-12: German standard used for testing fire resistance of cable trays, including exposure to temperatures up to 1000°C for 30, 60, or 90 minutes .
• E90 Rating: Ensures the tray maintains integrity for 90 minutes under fire conditions, commonly used in construction, power, oil, gas, and rail industries .

Processing and Installation

Fireproof cable trays are processed and installed with attention to fire safety:

• Intumescent Pads and Pillows: Used inside steel, PVC, or UPVC trunking to seal gaps and expand during fire, preventing fire spread .
• Pre-assembled Fittings: GRP and metal trays often come with pre-drilled straight sections, bends, couplers, and anchoring systems for faster installation .
• Cable Cleats and Supports: Recommended to maintain cable integrity and support during fire events, e.g., Ellis Patents Phoenix Cable Cleats .
• Custom Colouring and Coatings: Some suppliers offer tinted or coated trays for aesthetic or protective purposes without affecting fire resistance .

Pricing

Pricing varies based on material, size, and fire rating:

• Standard Steel or Wire Mesh Trays: Approximately £50–£100 per meter.
• Stainless Steel or High-Performance GRP Trays: £150–£300+ per meter depending on specifications and fire rating .
• Accessories and Fireproof Pads: Additional costs apply for intumescent pads, cleats, and covers.
