Fireproof cable trays in Iran

For fire-resistant cable tray solutions in Iran, FRP/GRP fiberglass trays, hot-dip galvanized steel trays, and PVC-coated trays are recommended, with additional fireproofing via intumescent coatings or firestop systems.

Key Options and Materials

1. FRP/GRP Fiberglass Cable Trays
   • Fire-resistant, flame-retardant, and electrically insulated.
   • Suitable for indoor and outdoor use, including industrial and high-rise buildings.
   • Can handle power cables below 10kV, control cables, lighting wiring, and other low-voltage systems .
2. Hot-Dip Galvanized Steel Trays
   • High resistance to moisture, corrosion, and chemical vapors.
   • Durable for long-term outdoor exposure and harsh environments.
   • Available in widths from 50 to 1100 mm and lengths of 2–3 meters .
3. PVC-Coated Cable Trays
   • Excellent resistance to humidity, acids, and chemical vapors.
   • Easy and fast installation, suitable for both indoor and outdoor applications .

Fireproofing Enhancements

• Intumescent Coatings: Provide a continuous protective layer that expands under heat, enhancing fire resistance. Easier to inspect and maintain compared to wraps .
• Firestop Systems: Essential for cable penetrations through walls, slabs, or shafts to prevent fire spread .
• Fire Wraps: Offer thermal protection and retrofit flexibility, particularly useful in dusty or hazardous environments .

Standards and Compliance

• Follow IEC 61537 for metallic cable tray systems, covering steel, stainless steel, and aluminum trays .
• Ensure fire ratings (EI60, EI90, EI120) are appropriate for the building type and local regulations .
• For critical infrastructure, high-rise buildings, or industrial facilities, select trays tested for fire endurance and environmental durability .

Recommended Suppliers in Iran

• Taliran Engineering Company: Official agent for SPINA/SCHIAVETTI TEKNO, offering a full range of cable trays, accessories, and technical support .
• Meka Pro: Provides fire-rated cable trays with extensive testing and certification for safety and durability .

Installation Tips

• Ensure proper spacing, bracing, and support according to load and fire rating requirements.
• Seal all penetrations with firestop materials to maintain compartmentalization.
• Consider reflective wraps or coatings in high-temperature or high-sunlight environments to preserve cable ampacity . By selecting the appropriate material, fireproofing method, and certified supplier, you can ensure safe, durable, and compliant cable tray installations in Iran.
