Galvanized cable trays painted with fire-retardant paint
Intumescent coatings are reactive fire-protection paints applied to the tray surface—often factory-applied to control thickness and quality. Under fire exposure, the coating expands to form an insulating char layer, slowing heat transfer. Most EPC specifications narrow the choice to two mainstream solutions: fire wrap systems (encapsulation) and intumescent fire-resistant. The bearing capacity of the trough bridge is strong, and it can withstand large cable load to. The fireproof channel cable tray system is produced by galvanized channel cable tray after processing surface treatment of a layer of fireproof coating.
