Can fireproof cable trays be painted Price
ALTIC 007 Fire Stop Coating is an advanced intumescent fire retardant paint engineered for electrical cables, trays, and penetrations. It combines certified performance (NTH Mumbai, ASTM, NFPA compliance) with eco-friendly, halogen-free, and durable protection. Selecting a fire protection method for cable tray systems is not a “nice-to-have”—it affects safety, compliance, maintenance disruption, and total installed cost. It first forms a dense zinc layer on the surface of the tray through galvanizing process to improve the anti-corrosion performance of the tray. Subsequently, on the basis of the galvanized layer, surface. CharCoat is an FM-Approved Intumescent Latex Cable Coating that stops fire from spreading on the cable surface at the source and simultaneously increases the fire resistance of the Electrical Power, Control or Communication Cable (single, grouped or in tray) for 90 minutes under IEC 60331-11/21.
