Are there any uncoated fireproof cable trays

Yes, uncoated fireproof cable trays are available, designed to provide inherent fire resistance without additional coatings.Inherently Fire-Resistant Cable TraysCertain cable trays, such as Cablofil fireproof trays, are engineered to be fire-resistant by design, meeting stringent fire safety standards like the German DIN 4102-12. These trays are tested in high-temperature ovens for durations of 30, 60, and 90 minutes at temperatures up to 1000°C, ensuring that the tray itself can withstand fire without requiring a separate coating or fireproof layer . They are widely used in industries where fire safety is critical, including construction, power, oil and gas, petrochemical, rail, and utilities .Coated vs. Uncoated TraysWhile many fireproof cable trays rely on coatings or fire protection tapes (e.g., FLAMMOTECT-A or DG-CR 0.7) to enhance fire resistance and environmental durability, uncoated trays achieve fireproofing through material selection and structural design. This eliminates the need for additional surface treatments, which can simplify installation and reduce maintenance concerns related to coating degradation over time .Applications and StandardsUncoated fireproof trays are suitable for low and high voltage cable installations in critical infrastructure, industrial plants, and public buildings. They are often paired with accessories like fire-rated cable cleats to maintain system integrity during fire events . These trays are designed to comply with national and international fire safety standards, ensuring reliable performance in emergency situations.SummaryIf you require a fireproof cable tray without coatings, look for products explicitly labeled as inherently fire-resistant or fireproof by design, such as Cablofil trays tested to DIN 4102-12. These trays provide robust fire protection while avoiding the need for additional coatings, making them suitable for demanding industrial and commercial applications .
