Fiber and communications infrastructure knowledge brief Published 01 Oct 2024

Prepared for preliminary research by the ENSAA knowledge desk. Confirm optical interfaces, port or core capacity, electrical input and output, enclosure protection, thermal design and installation limits against current standards and product documentation.

Cable trays can be made fire-resistant using metals like steel and stainless steel, non-metallic materials such as GRP, and specialized fire-protective coatings or tapes.

Metal Cable Trays

Steel is one of the most common materials for fire-resistant cable trays due to its strength and durability. Hot-dip galvanized steel provides corrosion protection but has limited fire resistance because the zinc coating melts at relatively low temperatures, making it less suitable for high-risk fire areas. Stainless steel offers superior durability and corrosion resistance and is preferred in environments where fire safety is critical, although it is not inherently fireproof.

These metal trays are widely used in commercial buildings, hospitals, and high-rise structures to maintain structural integrity under heat exposure.

Non-

Metallic Cable TraysGlass-Reinforced Plastic (GRP) cable trays are fire-resistant and non-combustible, meeting ASTM-E84 Class-1 standards. They are self-extinguishing (UL 94 V0 rated) and do not release toxic gases when exposed to fire, making them ideal for sensitive environments such as chemical plants, hospitals, and industrial facilities.

GR

P trays are lightweight, corrosion-resistant, and chemically resistant, providing both fire safety and durability.

Fire-

Protective Coatings and TapesSpecialized fire protection coatings and tapes, such as FLAMMOTECT-A and DG-CR 0. 7, can be applied to cable trays and cables to enhance fire resistance. These products form a protective shield that prevents flame propagation, maintains cable functionality during a fire, and withstands environmental factors like UV radiation, moisture, and chemicals.

They are particularly useful in high-risk areas like nuclear facilities, power stations, and industrial plants.

Firestopping Systems

In addition to tray materials, firestopping systems are used where cable trays pass through walls, slabs, or shafts. Materials such as fire-rated boards, firestop packs, firestop mastic, and fire-resistant mineral wool are installed to seal gaps and prevent fire and smoke from spreading. Proper installation ensures that openings around cable trays are tightly sealed, maintaining the overall fire safety of the building.

Summary

For fire-resistant cable tray installations, the main options include: Metal trays: Stainless steel and, to a lesser extent, hot-dip galvanized steel for structural strength and moderate fire resistance. Non-metallic trays: GRP trays for non-combustibility, self-extinguishing properties, and chemical resistance. Fire-protective coatings/tapes: Applied to enhance fire resistance and prevent flame propagation.

Firestopping materials: Used at penetrations to maintain fire compartmentalization. Selecting the appropriate material depends on the fire risk level, environmental conditions, and regulatory requirements of the installation site.
