Engineering Notes |
| Primary Dimensions |
|
|
| Side Rail Height (Depth) |
50 mm (Usable depth approx. 45–48 mm) |
Controls the volumetric cable capacity and structural rigidity. |
| Standard Width Options |
50 mm, 75 mm, 100 mm, 150 mm, 200 mm, 300 mm, 450 mm, 600 mm |
50mm–100mm widths are typically used for data, fiber optics, or instrumentation. |
| Standard Length |
2.4 meters, 3.0 meters (Most Common) |
3m lengths optimize fewer splice joins across long support spans. |
| Material & Thickness |
|
|
| Light Duty Thickness |
0.8 mm – 1.2 mm |
Ideal for communication/data bundles in ceiling voids. |
| Medium Duty Thickness |
1.2 mm – 1.5 mm |
Standard for general commercial and light industrial power runs. |
| Heavy Duty Thickness |
1.5 mm – 2.0 mm |
Used for high-vibration zones or long support spans. |
| Available Materials |
Carbon Steel, Stainless Steel (Grade 304/316L), Aluminum |
Steel dominates; aluminum and stainless are preferred for corrosive zones. |
| Perforation & Ventilation |
|
|
| Perforation Area / Rate |
30% – 40% open base area |
Class C or D ventilation rating under BS EN standards. Assists heat dissipation. |
| Slot Pattern Dimension |
Typically 12mm × 8mm (crosswise) & 20mm × 8mm (lengthwise) |
Configured for easy fastening of cable ties, cleats, and M6/M8 roofing bolts. |
| Standards Compliance |
|
|
| International Manufacturing |
IEC 61537 |
Global standard for cable tray systems management. |
| British & European Code |
BS EN 61537, BS EN 10346, BS EN ISO 1461 |
Governs mechanical testing, loading, and galvanization profiles. |
| North American Code |
NEMA VE 1 / CSA C22.2 No. 126.1 |
Governs load configurations and classifications. |
| Finishes & Corrosion Protection |
|
|
| Pre-Galvanized (Mill) |
Class 3 / 4 (Zinc coating ≈ 13–17 μm) |
Best for dry, indoor, commercial environments. |
| Hot-Dip Galvanized (HDG) |
Class 5 to 8 (Zinc coating ≈ 45–85 μm) |
Dipped after fabrication to protect punched slot edges; for outdoor use. |
| Powder Coated / Epoxy |
Variable micron layers over base metal |
Used for aesthetics (color coding) or specific chemical environments. |
| Mechanical Parameters |
|
|
| Recommended Support Span |
1.2 meters to 2.0 meters |
Spacing beyond 2m drastically reduces the safe working load limit. |
| Safe Working Load (SWL) |
35 kg/m to 120 kg/m (Varies by width and thickness) |
Calculated with a 1.5 safety factor under continuous load configuration. |
| Maximum Cable Fill |
40% Cross-Sectional Area Limit |
Standard NEC/IEC rule to avoid cable overheating and leave future expansion headroom. |
