Perforated Cable Tray – Ventilated Cable Management Solution

Perforated cable tray (also known as open-bottom cable tray) is manufactured from high-grade cold-rolled steel, stainless steel, or aluminum alloy, with regularly punched round or slotted holes on the bottom and side walls. This design provides excellent ventilation, heat dissipation, water drainage, and dust shedding while maintaining strong load capacity – offering a cost-effective cable support solution.

Key Features:

• Heat Dissipation – Open area promotes natural air circulation, reducing temperature rise in high-density cable runs and extending cable insulation life. Ideal for large power cables.

• Drainage & Debris Shedding – Water, dust, and small particles quickly fall through bottom holes, minimizing manual cleaning and maintenance.

• Lightweight Construction – 15–30% lighter than solid-bottom trays of the same size, reducing structural load and shipping cost.

• Easy Cable Securing – Cable ties or metal lashing wires can be attached directly to the punched holes, keeping wiring neat and allowing convenient branch exits.

• Economical – Higher material utilization and lower unit price than enclosed trays, suitable for large-area installation.

Applications:

• Industrial plants, power stations, substations for power cables

• Data center cold/hot aisles (ventilation requirements)

• Commercial buildings, office electrical/communication shafts

• Outdoor pipe racks and bridges where full watertightness is not required

• Manufacturing workshops and chemical plants (non-corrosive environments) for control cables
