Galvanized Perforated Cable Tray
Product Specification
| High Light | 50mm perforated cable tray ，perforated cable tray ，cable tray with perforations | ||
50mm perforated cable tray features a 50mm side rail height, providing reliable cable support, effective ventilation, and easy installation for light to medium-duty cable management systems.
| Parameter / Category | Specification / Standard Option | 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. |
