Complete List of Fire-Resistant Cable Tray Models and Specifications

Fire-resistant cable trays are specified based on material, fire integrity rating, environmental suitability, support systems, and compliance with regional and international standards.

Material and Construction

Fire-resistant cable trays are typically made from hot-dip galvanized steel for corrosion protection, with options for aluminized polypropylene scrim encapsulation or intumescent fire-resistant coatings to enhance fire performance . The tray design may include standard or lightweight construction, smooth edges, and compatible couplers to ensure safe cable routing and maintain circuit integrity . Stainless steel banding (SS316) is often used for securing trays in harsh environments .

Fire Performance Ratings

Cable trays are rated according to fire integrity standards, such as EI 60, 90, or 120, indicating the duration (in minutes) the tray can maintain circuit functionality under fire conditions . Some systems are tested to DIN 4102-12, which subjects the entire tray assembly to high temperatures (up to 1000°C) for 30, 60, or 90 minutes . These ratings are critical for facilities like hospitals, airports, tunnels, and industrial plants where circuit continuity is essential .

Compliance and Certification

Depending on the region, fire-resistant cable trays may require CE marking, ECAS certification (for UAE projects), and ATEX compliance for hazardous areas . Local regulations may also apply, such as German, Czech, or Slovak standards for circuit integrity under fire conditions .

Installation and Support

Proper installation is essential for fire performance. Specifications include:

• Correct support spacing to prevent sagging or joint stress
• Bend radius and alignment for cable integrity
• Field cutting and touch-up procedures to maintain protective finishes
• Use of slotted strut channels, brackets, beam clamps, and anchors for suspended trays

Accessories and Compatibility

A complete specification should cover elbows, reducers, covers, and bonding hardware to ensure the tray system functions as a cohesive unit . Accessories like Phoenix Cable Cleats may be recommended to preserve fire performance and cable security .

Environmental Considerations

Fire-resistant trays are selected based on the installation environment: indoor, outdoor, humid, corrosive, dusty, or impact-prone areas. Heat dissipation, route identification, and separation of emergency, communication, and power circuits are also considered .

Summary

A complete range of fire-resistant cable tray specifications includes:

• Material: Hot-dip galvanized steel, coated or wrapped for fire resistance
• Fire rating: EI 60, 90, 120 or DIN 4102-12 tested
• Compliance: CE, ECAS, ATEX, or local standards
• Installation: Supports, bend radius, field treatment, and alignment
• Accessories: Couplers, covers, cleats, and bonding hardware
• Environmental suitability: Indoor/outdoor, corrosive, humid, or high-risk areas

These specifications ensure that critical circuits remain functional during fire events, meet regulatory requirements, and provide safe, maintainable cable routing for demanding projects .
