Select tray materials and finishes that match the hazard: hot‑dip galvanised steel or stainless for durability; aluminium for lighter loads; FRP for corrosive plants. Pair trays with low‑smoke, halogen‑free cables in occupant areas to reduce toxic fumes. Materials like steel, aluminum, and fiber-reinforced plastics all behave differently in the presence of fire, so understanding how they perform can help ensure that your installation remains safe and compliant with fire protection regulations. Where cables pass through shafts, walls, slabs, or enter electrical panels or cabinets, openings shall be tightly sealed with firestopping materials in accordance with design requirements. The following charts give the number of 3M pillows needed to completely firestop an opening that cable tray passes through.
