Common gauges are 1.2, 1.6, 2.0 and 2.5 mm. 1.2 mm suits light control cabling on short spans, 1.6 mm is the general-purpose default, and 2.0 to 2.5 mm is for heavy power runs, wide trays or long support spans. Rather than order by gauge alone, give the cable load per metre and support spacing, and let the manufacturer confirm the thickness.

Add the cross-sectional area of all cables, then keep the fill ratio below about 40% of the tray's internal area so heat can dissipate, per IEC 61537 practice. Don't stack a single layer of power cable; for control cable, 40% fill is acceptable. Share the cable schedule and we can confirm tray width, depth and load class before fabrication.

A credible Indian manufacturer ships a commercial invoice, packing list, Mill Test Certificate (MTC) tracing the steel to its heat, a galvanizing certificate stating zinc thickness, and a Certificate of Origin (COO) for duty relief. Third-party inspection reports from SGS, TÜV or Bureau Veritas are added where the buyer or the standard requires them.

Five things separate good supply from low-cost supply. Gauge: is the quoted thickness the base metal or the total with galvanizing? A 1.6 mm base pre-galvanized tray is not the same as a 1.6 mm finished tray. Return flange: does the tray have a doubled edge or a raw cut edge? Raw cut edges damage cable insulation during installation and are not acceptable on international tenders. IEC 61537 load class: is the load rating supported by a type-test report or a self-declaration? Finish consistency: is galvanizing in-house or outsourced? If outsourced, zinc thickness varies by batch. Accessory matching: can the supplier provide bends, tees and couplers in the same material and thickness? Getting the answers to these five before you compare prices prevents a lot of site rework.
