Al-Zinc-Magnesium Alloy (ZAM): 53% aluminum, 43% zinc, 2% magnesium, 1. 5% silicon; provides excellent corrosion resistance and durability ( ).

Fire-

Resistant Coatings: Intumescent or specialized fireproof powders enhance flame retardancy and prevent fire spread along cable runs ( ).

Applications

Industrial plants (chemical, petroleum, metallurgy)Commercial buildings and data centersEmergency systems (fire alarms, lighting, communication networks)Environments requiring high fire safety and corrosion resistanceNotes on SelectionTray type should match cable type and load requirements. Ladder trays are ideal for heavy cables, while perforated or wire mesh trays suit lighter or flexible cables. Material choice depends on environmental exposure: aluminum and FRP for corrosion-prone areas, galvanized or stainless steel for high mechanical strength.

Fire rating and coating selection are critical for compliance with local fire safety regulations and to ensure operational continuity during emergencies ( ). These specifications provide a comprehensive reference for selecting and designing flame-retardant cable tray systems in China, ensuring safety, durability, and regulatory compliance.
