Bending 100 mm Perforated Cable Tray is a compact and efficient cable management system designed for routing and supporting control, signal, communication, and light-load power cables. With evenly distributed perforations, it provides good ventilation, easy cable fixing, and flexible installation, making it ideal for indoor and light industrial applications.
Bending 100 mm Perforated Cable Tray Key Features
Ventilated Base: The tray features a systematic pattern of punched holes (slots) that facilitate maximum airflow. This prevents heat buildup, allowing cables to operate at their full current-carrying capacity
Integrated Hole Pattern: The perforations are not just for air; they are designed as mounting points. They allow for easy fastening of cables using cable ties or specialized clamps without the need for additional drilling.
Structural Rigidity: Despite its light-duty classification, the side rails are usually formed into a "C-profile" or "Return Flange," which significantly increases the tray's stiffness and prevents twisting under load.
Electrical Continuity: High-quality trays are designed to act as an Equipment Grounding Conductor (EGC). When properly coupled, they provide a continuous path to the ground, ensuring safety in the event of a short circuit.
Typical Projects of Bending 100 mm Perforated Cable Tray
Commercial Buildings (Most Common): Office Fit-Outs: Carrying structured cabling (Cat6/6A, fiber) above ceilings or under raised floors from telecom rooms to workstations.
Retail Stores & Hotels: Distributing power, lighting, data, and security system cables in corridors and ceiling voids.
Light Industrial & Workshop Areas: Supporting control wiring, low-voltage instrumentation, and small power cables for machinery, lighting, and HVAC systems. Not for heavy power feeders.
IT & Network Closets / Server Rooms: Secondary Routing: Used for organized, accessible pathways from main distribution frames to switches and patch panels, often above or below racks.
Public & Institutional Buildings. Schools, Libraries, Community Centers: Managing the mixed low-voltage infrastructure for data, audio-visual, and access control systems.
Common Specifications, Standards, and Parameters of Bending 100 mm Perforated Cable Tray
| Parameter |
Typical Specification / Detail |
| Inside Width (W) |
100 mm (nominal). Common outside width is ~115-120mm, depending on side rail design. |
| Side Height (H) |
Common heights: 25mm, 50mm, 75mm, 100mm. 50mm is a popular standard depth. |
| Material & Finish |
Material: Pre-galvanized steel (G30, G60), hot-dip galvanized steel, aluminum 6063, 6061, or 5052, stainless steel (304, 316). |
| Finish: Mill galvanized, hot-dip galvanized, powder coating, and anodizing (for Al). |
| Perforation Pattern |
Standard: Round or oval holes. Hole size and pitch are designed for ventilation, cable friction, and EMI containment. |
| Rung/Cross-Bar Spacing |
Typically, 50mm or 100mm center-to-center spacing for strength and cable support. |
| Thickness (Gauge) |
Side Rails/Rungs: 1.0mm to 2.0mm (18 to 14 SWG / ~0.036” to 0.075”). Varies with material and load class. |
| Bending Radius |
Standard inside radii for horizontal bends: 300mm, 450mm, 600mm. |
| Straight Length |
Common standard lengths: 2.44m (8 ft), 3.05m (10 ft), or 6m. |
| Load Class / Rating |
Based on standard (e.g., NEMA Class 1-4, IEC “C” Light, “B” Medium, “A” Heavy). A 100mm tray is typically Class 1/C (Light Duty) or Class 2/B (Medium Duty). |
Bending 100 mm Perforated Cable Tray's advantages
- Space & Material Efficiency Creates precise, compact turns to navigate tight corners without wasting space or needing multiple straight sections and fittings.
- Aesthetic & Professional Installation: Provides clean, continuous lines with no gaps or offsets, resulting in a smoother, more professional-looking installation compared to using standard pre-made elbows.
- Improved Cable Pulling & Protection allows for controlled, gentle bend radii that meet or exceed cable manufacturers' minimum requirements, reducing pulling tension and risk of cable damage.
- Customization & Flexibility enables on-site adaptation to unique building layouts, obstacles, or last-minute design changes without waiting for special-order factory fittings.
- Structural Integrity, A properly fabricated bend from a continuous section of tray maintains side rail strength better than a joint at a pre-fabricated fitting, reducing potential weak points.
- Cost & Time Savings: Can reduce the total number of components (couplers, bolts, elbows) and simplify installation logistics, potentially lowering material and labor costs for complex runs.
