Cable Trays
Importers in Detroit

Yes, where it's listed for the duty. NEC 392.60 and IEC 61537 both permit a metallic tray to act as an equipment grounding conductor, provided its cross-section meets the fault-current table and every joint keeps electrical continuity (galvanizing removed at bonding points, jumpers fitted across expansion joints). Confirm the tray is approved for EGC use before you rely on it for that path.

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.

Commercial real estate, Grade A offices, hospitals and retail malls, is the largest single market: HDG or pre-galvanized trunking in 75×50 to 150×75 mm for power, data and fire routes in partition walls and raised floor voids. Pharmaceutical plants (Hyderabad, Pune, Ahmedabad) specify stainless 304 trunking for cleanroom and production-area runs, with screw-fixed covers and welded continuous joints. Telecom data centres in Mumbai, Hyderabad and Chennai use 200×100 mm HDG trunking for horizontal cable management between cabinets. Metro rail projects specify fire-rated HDG trunking with IEC 61537 fire integrity evidence for signal and communication runs. We stock all four profiles and can consolidate mixed-product deliveries on a single bill of lading.
