Cable Trays
Importers in Melbourne

Plan for bends (horizontal and vertical), tees, crosses, reducers, covers, couplers or splice plates, and support brackets, all in the same material and finish as the tray. One mistake we see constantly: ordering tray without accessories, then air-freighting a second small shipment of bends and tees at a premium once the gap shows up on site. Count the full accessory list into your enquiry from the start.

Support spacing usually runs 1.5 to 3.0 m depending on load class and cable weight. A tray rated at a 1.5 m span will deflect noticeably more at 3 m, so span and load can't be judged separately; they're two sides of the same number. Tell us the cable weight per metre and your preferred support spacing and we'll confirm the correct gauge and load class.

Aluminium suits weight-sensitive installations and mildly corrosive environments. It's naturally corrosion-resistant and roughly a third the weight of steel, though the trade-off is lower mechanical strength, which shortens support spans. For most heavy power and outdoor runs, hot-dip galvanized steel remains more economical. Aluminium earns its premium on rooftops, offshore topsides and long horizontal runs, where every kilogram saved matters.

Perforated trays are right when the cable route carries smaller cables, control wiring, instrumentation, Cat 6A data, BMS signals, fire-detection loops, where continuous bottom support prevents sagging between rungs. They also suit pharmaceutical cleanrooms, hospital technical floors and commercial Grade A office fit-outs where cleanliness and aesthetics matter alongside function. For heavy LT power cable above 240 mm² or long support spans exceeding 2 m, ladder tray is the better thermal and structural choice.
