Perforated Cable Tray

India Electricals Syndicate has manufactured perforated cable trays at its Howrah works in West Bengal since 1972. The perforated profile — a slotted base pressed into a rigid channel section — keeps power and control cables ventilated, dissipates heat along long horizontal runs, and lets dust, moisture and condensate fall away instead of collecting on the cable bed. It remains the most widely specified cable management system for Indian power, refinery, steel and infrastructure projects where airflow and serviceability matter.

Each tray is press-braked from certified cold-rolled steel coil with a controlled 35% open perforation area, then formed into widths from 50 mm to 900 mm in 1.2 mm to 2.5 mm sheet. The return-flanged side rails deliver a high strength-to-weight ratio, supporting up to 150 kg/m on a three-point load with minimal deflection — sufficient for densely loaded panel rooms, cable galleries and outdoor racks without intermediate supports at close centres.

Manufacturing is held to IEC 61537 and IS:12352, with raw material to ASTM A653 / EN 10346. Trays are supplied pre-galvanized in Z275 or Z350 zinc class, hot-dip galvanized to 85 micron for aggressive outdoor and coastal duty, or powder- and epoxy-coated where a specific finish or colour is required. Stainless SS 304 / SS 316 construction is available for offshore and chemical service. Every despatch is backed by mill test certificates, in-house inspection records and project-specific packing lists.

Perforated cable trays from IES are routed into power distribution panel rooms, data centres, refineries, hospitals, railway and metro systems and offshore installations across India.
