For mild-steel, hot-dip galvanized tray FOB India: perforated 100 mm runs roughly USD 3 to 6 per metre, ladder 300 mm roughly USD 8 to 15, climbing to USD 15 to 28 at 600 mm width. Treat these as planning numbers, not a quote. Steel cost, gauge, zinc thickness and order size move the real figure, and volume orders settle toward the lower end of each range.

Hot-dip galvanized after fabrication (IS 4759 / ASTM A123, 65 to 85 microns) coats cut edges and welds, and that's what any outdoor, humid or coastal project needs. Pre-galvanized tray, at around 20 microns with bare cut edges, is cheaper but belongs indoors in dry conditions only. If a quote looks 15% lower than a competitor's, check whether you're comparing pre-galv against hot-dip. They aren't the same product.

IEC 61537 is the global cable-management standard. It sets the safe working load, deflection class and corrosion class. For US-spec projects, add NEMA VE 1; for Indian-standard purchases, add IS 12352. Galvanizing sits outside both and is specified separately, to ASTM A123 or IS 4759. Reference IEC 61537 in the BOQ and ask the supplier for the load-deflection type-test report.

Closed trunking shields cables from dust, falling debris, mechanical impact and casual contact, choose it for switch rooms, exposed building runs, walkway-adjacent routing and areas with public access. Open trays cost less and dissipate heat better, but they expose the cabling. Many EPCs mix the two: trunking in occupied zones, trays in plant rooms.
