A fire survival cable tray is a passive fire protection system designed to keep critical circuits-fire-fighting equipment, emergency lighting, alarm systems-operating during a fire. It is more than a coated support: the trough uses a double-layer steel plate filled with non-toxic intumescent fireproof material that swells rapidly when heated to form a dense, heat-insulating carbonized layer. Internal partitions separate cable systems inside the tray, and fireproof sealants and blocking materials maintain compartment integrity where the tray passes through walls or floors. The system keeps the cable environment's integrity, stability and thermal insulation for a rated duration of 60, 90 or 120 minutes, preserving "lifeline" circuits.
We control the fire survival cable tray through material specification of the fireproof coating composition and consistent batch production. The intumescent filler chemistry and double-sheet construction are fixed before production, and each run follows the same fill and curing process so the expansion layer performs predictably across the whole order. Because fire survival depends on every tray piece responding the same way under heat, this batch consistency gives buyers confidence that the rated 60/90/120-minute function holds uniformly from the first section to the last, rather than varying by hand-applied coating.

Applications
- High-rise buildings, hospitals and commercial complexes protect vertical cable shafts and refuge-area circuits; the rated 60–120 minute survival keeps emergency lighting and alarms running through evacuation.
- Broadcasting centers, data centers and power dispatch centers treat their power and signal routes as lifelines; the system preserves operation during fire events to minimize outage and data loss.
- Chemical plants and oil facilities need cable channels that do not spread fire; the intumescent layer and internal partitions slow flame travel while keeping fire-fighting circuits energized.
Customization
We customize the fire survival rating (60 / 90 / 120 min), tray width and depth, number of internal partitions, penetration seal configuration, and accessory set, produced to a fixed intumescent fill specification.
Packaging & Transportation
Sections are packed in fumigation-free plywood crates reinforced for international transport. Terms: FOB, EXW, DDP; payment by T/T.
FAQ
Q: What fire survival durations are available?
A: We build to rated 60, 90 or 120-minute survival classes, selected to the project's required code level.
Q: Is the fire performance consistent across a large order?
A: Yes. The intumescent fill and double-sheet process are standardized per batch, so expansion and insulation performance stay uniform across all sections.
Q: Do you supply the seals for wall and floor penetrations?
A: Fireproof sealant and blocking materials are specified as part of the system so compartment integrity continues through penetrations.
