Cable Tray Price in Pakistan 2026 — IEC 61537 Buyer Guide + Full Price Matrix
Cable tray prices in Pakistan for 2026 swing from PKR 850/metre for a 50mm galvanized perforated tray up to PKR 12,500/metre for a 600mm hot-dip galvanized ladder tray. The pricing depends on width, depth, sheet thickness, surface finish, and load class. This guide explains the IEC 61537 tray-class system, gives a complete Pakistani 2026 price matrix, and shows the 6 mistakes Pakistani electricians make when picking trays for solar DC, industrial AC, or telecom cable runs.
1. Cable tray vs cable trunking vs conduit — pick the right one
| Cable tray (perforated/ladder) | Cable trunking (closed) | Conduit (round pipe) | |
|---|---|---|---|
| Ventilation | High (perforated) | None (sealed) | None |
| Cable changes | Easy (lay-in) | Medium (open lid, route) | Hard (pull through) |
| Cable count capacity | 20-200+ cables | 10-80 cables | 2-10 cables |
| Heat dissipation | Excellent | Poor | Poor |
| Best use | Industrial, server, solar farm | Office, indoor wall runs | Underground, point-to-point |
| 2026 Pakistani price per metre (300mm wide) | PKR 2,200 - 4,800 | PKR 1,650 - 3,200 | PKR 165 - 485 (per pipe) |
2. Cable tray types — perforated vs ladder vs solid bottom
Perforated tray
Steel sheet bottom with rectangular ventilation cutouts (typical 12×30 mm). Most common in Pakistani industrial / commercial work. Balances cable support, heat dissipation, and cost.
Ladder tray
Two side rails connected by transverse rungs (no bottom sheet). Best heat dissipation. Used for high-current power cable runs (large copper feeders, busbars). More expensive due to fabrication complexity.
Solid-bottom tray
Steel sheet bottom with no perforations. Used for sensitive control cables that need protection from dust / chemicals / falling debris. Worst heat dissipation — not for power runs.
Wire-mesh tray
Welded wire grid. Lightest weight, fastest install, used heavily in data centres + telecom. Pakistani prices PKR 1,800 - 3,500/metre for 300 mm.
3. IEC 61537 load classes — how to read the spec
IEC 61537 (the international cable tray standard) rates trays by working load limit at a given support span. A class number tells you the maximum load (kg/metre) the tray will hold over that span without exceeding 1/200th deflection.
| IEC 61537 class | Max load at 2m support span | Typical Pakistani use |
|---|---|---|
| Class I | 1.5 kg/m | Telecom, structured cabling |
| Class II | 4.5 kg/m | Low-current control wiring |
| Class III | 9 kg/m | Light industrial, lighting branch circuits |
| Class IV | 15 kg/m | Mixed power + control (most Pakistani factories) |
| Class V | 30 kg/m | Heavy power feeders (sub-station to MCC runs) |
| Class VI | 50 kg/m | Very heavy — main substation feeders |
4. Surface finish — pre-galvanized vs hot-dip vs powder-coat
- Pre-galvanized (electro-galv): 7-15 micron zinc applied to sheet before fabrication. Cheapest. Indoor dry use only — rusts within 1-2 years if exposed to weather or chemicals.
- Hot-dip galvanized: 55-85 micron zinc applied after fabrication, covers cut edges. Standard for outdoor + industrial Pakistani work. 20-30 year life in Lahore/Karachi humid environments.
- Powder-coat over galvanized: additional 60-100 micron polyester powder coat (typical RAL 7035 grey or 5015 blue). Used in cleanroom + food processing where flaking zinc is unacceptable.
- Stainless steel (304 or 316): chemical plant, refinery, coastal Pakistan. PKR 4× - 8× the hot-dip price.
5. Pakistani 2026 price matrix — perforated tray (hot-dip galvanized)
| Width | Depth 50 mm | Depth 75 mm | Depth 100 mm |
|---|---|---|---|
| 50 mm | PKR 850/m | PKR 1,050/m | PKR 1,250/m |
| 100 mm | PKR 1,150/m | PKR 1,400/m | PKR 1,650/m |
| 150 mm | PKR 1,450/m | PKR 1,750/m | PKR 2,050/m |
| 200 mm | PKR 1,850/m | PKR 2,200/m | PKR 2,600/m |
| 300 mm | PKR 2,650/m | PKR 3,150/m | PKR 3,750/m |
| 400 mm | PKR 3,650/m | PKR 4,350/m | PKR 5,150/m |
| 500 mm | PKR 4,850/m | PKR 5,750/m | PKR 6,800/m |
| 600 mm | PKR 6,250/m | PKR 7,400/m | PKR 8,750/m |
| 800 mm | PKR 9,250/m | PKR 10,800/m | PKR 12,500/m |
Add ~25% for ladder tray (same width/depth). Subtract ~15% for pre-galvanized (indoor only). Add 100-150% for hot-dip 316 stainless (coastal / chemical).
6. Accessories — budget for these (15-20% of tray cost)
| Accessory | 2026 Pakistani price |
|---|---|
| Horizontal bend (90°) | PKR 850 - 4,500 |
| Vertical bend (inside/outside) | PKR 950 - 5,200 |
| Tee / Cross junction | PKR 1,650 - 8,500 |
| Reducer (e.g., 300 to 200 mm) | PKR 1,150 - 3,800 |
| Coupler / splice plate set | PKR 165 - 485 |
| Tray cover (where required) | PKR 650 - 4,800/m |
| Support bracket (wall / ceiling) | PKR 350 - 1,250/each |
| Threaded rod hanger (M10, per metre) | PKR 285/m |
7. How to size cable tray width — the 40% fill rule
NEC and Pakistani factory inspection custom both limit cable tray fill to ~40% cross-sectional area (allows airflow + future expansion). Quick sizing formula:
- Add up the cross-sectional areas of all cables you'll run (cable OD × cable OD × π / 4)
- Divide by 0.4 (40% fill limit)
- Divide by tray inside depth to get required width
Example: running 15× 4-core 6 mm² XLPE cables (OD ~16 mm each, area ~200 mm²). Total area = 3,000 mm². Divided by 0.4 = 7,500 mm² required tray cross-section. With 75 mm tray depth: 7,500 / 75 = 100 mm minimum width — choose next standard size up = 150 mm wide tray.
8. Solar DC cable tray — special considerations
Solar PV strings run at 600-1500 VDC. Pakistani solar farms must use:
- UV-resistant tray finish (hot-dip galvanized OR powder coat — not pre-galv)
- Separation of positive and negative cables in adjacent trays (IEC 60364-7-712)
- DC-rated DC isolator at array, sub-array, and inverter input
- Earthing continuity — bond each tray section to the next with a bond strap (don't rely on coupler contact)
- Rooftop tray runs need additional UV cover or sun shield to prevent cable jacket degradation
9. Industrial 3-phase tray — cable separation rules
For Pakistani factory installations carrying both power and control cables:
- Power cables (LV + MV) in separate tray or with metal divider from low-voltage signal cables
- Lighting branch circuits OK with general power if grouped by phase
- Minimum tray-to-tray vertical clearance for heat: 300 mm
- Minimum tray-to-wall: 150 mm for service access
- Earth bond every tray section to building earth via < 50 cm bond strap
10. Six mistakes Pakistani electricians make
- Buying pre-galvanized for outdoor or rooftop solar runs. Save PKR 200/m, lose tray in 18 months. Always hot-dip for any outdoor or humidity exposure.
- Ignoring the 40% fill rule. Stuffed tray runs hot, derates cables 15-25%, voids manufacturer warranties.
- Not earthing each tray section. Coupler bolts loosen over years — tray becomes a floating conductor in fault conditions.
- Mixing brands of tray + accessories. Slot patterns differ; couplers don't mate. Stick with one manufacturer per run.
- Under-supporting spans. Tray manufacturer rates load at 2m span. Pakistani contractors often go 3m to save support brackets — tray sags, cables stress.
- No future cable allowance. Building for today's cable count — tomorrow's expansion forces full re-pull.
11. FAQ
Cable tray vs cable ladder — which is better for heavy power runs?
Cable ladder for any run with 50 mm² or larger copper feeders — the open rung design dissipates heat dramatically better than perforated tray. Perforated tray for mixed power + control runs where you want cables held against a flat bottom for tidy lay-up.
How much extra to budget for accessories (bends, tees, supports)?
Plan 15-25% of tray straight-section cost for accessories in typical Pakistani industrial work. Increase to 30-35% if the run has many direction changes or vertical risers.
Can I use cable tray for outdoor low-voltage data + telecom runs?
Yes — wire mesh tray with hot-dip or powder-coat finish is the lightest, fastest install for telecom + data. Maintain 300 mm separation from any AC power cables to avoid electromagnetic interference.
What sheet thickness should I specify for tray under 200 mm wide?
1.0 - 1.2 mm is standard for trays up to 200 mm wide. Above 300 mm wide, specify 1.5 mm minimum. Above 600 mm, 2.0 mm is needed to prevent flex under cable load.
Where to source bulk cable tray in Pakistan?
For projects above 200 metres, contact tray fabricators in Lahore Industrial Estate, Karachi SITE, or Faisalabad Khurrianwala for direct factory pricing. Below 200 metres, retail electrical shops on Hall Road Lahore or Jodia Bazar Karachi stock 50 - 300 mm widths.
