The Galvanized Perforated Cable Tray is a versatile, lightweight, and cost‑effective solution for indoor electrical cable management. The perforated bottom provides excellent ventilation while allowing small cables to be easily supported and routed. Hot‑dip galvanized (HDG) or electro‑galvanized finish ensures reliable corrosion resistance for general industrial and commercial applications.
Perforated design – ventilation + small cable support
Galvanized finish – HDG (≥65µm) or electro‑galvanized (Z12‑Z25)
Easy installation – lightweight, pre‑punched splice holes
Compliant with NEMA VE 1 / IEC 61537

Custom widths, heights, and hole patterns available on request.
| Hole Type | Diameter (mm) | Hole Spacing (mm) | Typical Open Area | Application |
|---|---|---|---|---|
| Round – small | Φ5 | 10 × 10 | 30% | Control / instrument cables |
| Round – standard | Φ6 – Φ8 | 15 × 15 | 40% | General purpose |
| Round – large | Φ10 | 20 × 20 | 50% | High ventilation, small cables |
| Slotted (rectangular) | 6 × 25 | staggered | 45% | Easier cable tie‑down |
| Load Class | Typical Thickness (Ga/mm) | Max Safe Span (m) | Load Capacity (kg/m) | Typical Applications |
|---|---|---|---|---|
| Light Duty (LD) | 20 Ga (0.8 – 1.0 mm) | 2.0 – 2.5 | 50 – 80 | Office cabling, control cables, small data lines |
| Medium Duty (MD) | 16 Ga (1.2 – 1.5 mm) | 2.5 – 3.0 | 80 – 120 | Industrial power & control, equipment rooms |
| Heavy Duty (HD) | 14 Ga (1.5 – 2.0 mm) | 3.0 – 3.5 | 120 – 180 | Heavy power cables, dense fills |
| Extra Heavy Duty (EHD) | 12 Ga (2.0 – 2.5 mm) | 3.5 – 4.0 | 180 – 250 | Substations, power plants, long spans |
Load capacity includes both cable weight and a safety factor. For exact loads, consult load tables.
| Finish Type | Coating Thickness | Corrosion Resistance (Salt Spray) | Appearance | Best Environment |
|---|---|---|---|---|
| Electro‑galvanized (Z12‑Z25) | 12 – 25 µm | 100 – 200 hours | Bright, smooth | Indoor, dry, mild climate |
| Hot‑dip galvanized (HDG) | ≥65 µm (ASTM A123) | 500 – 1000+ hours | Matte, grey | Industrial, outdoor, moderate humidity |
| Pre‑galvanized (mill galvanized) | 20 – 30 µm | 200 – 300 hours | Spangled | Warehouse, light industrial |
| HDG + Passivation | ≥65 µm + chromate | 800+ hours | Slightly tinted | Coastal / high humidity indoor |
Recommendation: Use HDG for any outdoor or mildly corrosive indoor environment. Electro‑galvanized is sufficient for clean, dry indoor areas such as offices or control rooms.
| Feature | Benefit |
|---|---|
| Perforated bottom | Allows air circulation, heat dissipation, and small cable branching |
| Pre‑punched splice holes | Faster assembly, no on‑site drilling |
| Easy cable tie‑down | Perforations accept cable ties at any point |
| Lower weight | 15‑25% lighter than solid bottom trays – reduced shipping & labor cost |
| Versatile | Use with or without covers; suitable for ladders or troughs |
| Zinc coating protection | Prevents red rust; life expectancy 10‑25 years depending on environment |
