How to bend a mesh cable tray

Wire mesh cable trays can be bent on-site using simple tools like bolt cutters and pliers, allowing for horizontal, vertical, and T-junction bends without specialized fittings.Tools and Safety Equipment

To bend a mesh cable tray safely, you will need:

• Bolt cutter or cable cutter for cutting mesh wires
• Pliers or nose pliers for fine adjustments
• Measuring tape and marker to mark bend locations
• Hand gloves to protect your hands from sharp edges
• Optional rubber caps to cover cut ends for safety and protection .

General Steps for Bending

1. Mark the Bend Area: Use a marker or chalk to indicate where the bend will occur. Ensure the measurement is precise to maintain proper alignment .
2. Cut Selected Wires: For sharper bends, cut specific mesh wires along the bend line using a bolt cutter. This allows the tray to flex without deforming the entire structure .
3. Bend the Tray: Apply steady pressure to bend the tray along the marked line. For horizontal bends, bend within the same plane; for vertical bends, lift or lower the tray to the desired angle .
4. Smooth the Edges: After bending, use pliers to adjust any protruding wires and ensure a smooth surface for cable protection .
5. Reinforce if Needed: For larger or structural bends, consider adding reinforcement to maintain tray strength and prevent sagging .

Types of Bends

• Horizontal 90° Bend: Changes direction within the same plane, ideal for routing around walls or machinery .
• Vertical Up/Down Bend: Moves the tray to a higher or lower level, useful for ceiling-to-floor transitions .
• T-Junction Bend: Allows branching of cables from the main tray .
• Offset Bend: Shifts the tray sideways to navigate obstacles .

Tips for Best Results

• Maintain a proper bend radius to avoid damaging Ethernet or fiber cables .
• Avoid overfilling trays at corners to ensure smooth cable routing .
• Verify grounding and bonding after modifications to maintain electrical safety .
• Work slowly and carefully to preserve the tray's structural integrity and aesthetic appearance . By following these steps and using the right tools, you can create professional, safe, and efficient bends in wire mesh cable trays directly on-site without relying on pre-fabricated fittings .
