Fireproof cable trays are generally made from painted or galvanized steel, stainless steel, aluminum alloys, or fiberglass-reinforced plastics, depending on the environment and exposure conditions . The tray thickness is selected based on the number and weight of cables, ensuring sufficient mechanical strength to prevent deformation under full load . For standard steel trays, thicknesses typically range from 1.5 mm to 3 mm, with thicker trays used for heavy-duty or high-load applications .
Fireproof cable trays often include insulating wraps or coatings, such as FireMaster® blankets, which are applied around the tray to maintain cable operation during fires for a specified duration (e.g., 30 minutes for hydrocarbon fires), . The insulation thickness is usually 50–75 mm, depending on the tray width and fire rating, and is secured with steel banding straps at regular intervals . These measures are critical to comply with fire safety standards and ensure reliable operation during emergencies.
When installing fireproof trays, it is important to follow technical standards for layout, spacing, and firestopping, including proper sealing at wall or slab penetrations . The tray thickness must be compatible with the fireproofing system and structural supports, and periodic inspections are recommended to verify coating integrity and mechanical stability . Compliance with CE marking and European directives ensures that the trays meet minimum safety and fire resistance requirements .
