Cable Trays
Importers in San Jose

Ladder tray suits heavy power cable: open rungs dissipate heat and allow long support spans. Perforated tray, with a slotted base, is the default for control and instrumentation cabling. Trunking, fully enclosed with a cover, protects against dust and impact in exposed or occupied areas. Most projects end up mixing all three, matched to what each run actually carries.

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.

Yes. Even though aluminium is conductive, the oxide film insulates joints, so a discrete earth strap with toothed washers at each joint, and a tray-to-structure bond at intervals, is needed for EMC and fault-clearing. IS/IEC bonding rules apply equally to aluminium.
