Fireproof cable tray color and model

Fireproof cable trays are available in various models and finishes, with color often indicating material type or fireproof coating, and selection depends on fire rating, environment, and compliance standards. Types and ModelsDAKEN Fire-Resistant Cable Tray (DFCT)Constructed with an epoxy-based intumescent fire protection system and internal metal reinforcement. Provides high structural stability, long-span installation support, and excellent fire resistance.

Suitable for nuclear power facilities and high-risk fire environments. Typically comes in neutral or light gray epoxy finish, which is standard for fireproof coatings. FireMaster® Cable Tray WrapDesigned for instrument control cables, providing 30 minutes of hydrocarbon fire protection.

Uses FireMaster® Marine Plus blanket fully encapsulated in aluminum foil, secured with SS316 stainless steel banding. Can be installed over open or mesh trays, with overlaps and banding ensuring fire integrity. Color is generally metallic silver due to aluminum foil encapsulation.

Aluminized Polypropylene Scrim or Intumescent Coating Trays

Base tray often hot-dip galvanized steel for corrosion protection. Fireproofing achieved via wrapping or coating, with coatings typically red, orange, or gray depending on manufacturer standards. Models are selected based on fire rating (EI 60, 90, 120), environmental conditions, and compliance with CE, ECAS, and ATEX standards.

HERMI E90 Fire-

Resistant Cable Tray

Constructed for surface cable laying with standard or lightweight paths. Color coding may follow project-specific or regional standards, often gray or metallic for fire-resistant trays.

Color Coding Considerations

Gray or metallic finishes: Common for epoxy or aluminum-based fireproof coatings. Red or orange: Sometimes used to indicate high fire-resistance rating or emergency circuits. Manufacturer-specific colors: Some suppliers may use proprietary colors to indicate fire rating or material type.

Selection Criteria

Fire Rating: Choose trays rated for the required EI duration (e.g., 60, 90, 120 minutes). Material: Options include galvanized steel, stainless steel, aluminum, or epoxy-coated steel. Environment: Consider corrosive, high-temperature, or explosive atmospheres.

Compliance: Ensure trays meet local and international standards (CE, ECAS, ATEX). Accessories: Include banding straps, mesh liners, covers, and ventilation grilles for optimal fire performance.

Summary

When choosing a fireproof cable tray, consider model type, fireproofing method, material, color coding, and compliance requirements. Standard colors like gray, metallic, or red often indicate fire-resistant coatings or high-risk circuits. Models such as DAKEN DFCT, FireMaster®, and HERMI E90 provide options for different fire ratings and environmental conditions, ensuring both safety and operational reliability.
