Methods for bending and fixing mesh cable trays

Mesh cable trays can be safely bent and fixed on-site using simple cutting, bending, and clamping techniques, allowing flexible cable routing without specialized fittings.

Tools and Safety Equipment

To bend and fix mesh cable trays, you will need:

• Bolt cutter or cable cutter for cutting tray sections
• Pliers or nose pliers for wire manipulation
• Measuring tape and marker/chalk for accurate bend placement
• Hand gloves and safety gear to protect against sharp edges and zinc-coated wires

Bending Techniques

Mesh cable trays are highly flexible and can be modified directly on-site. Common bends include:

• Horizontal 90° Bend (Flat Bend): Mark the bend line, cut selective wires if needed, and fold the tray along the line to form a smooth corner .
• Vertical Bend (Up/Down): Lift or lower the tray section to navigate ceiling or floor transitions, maintaining a proper bend radius to avoid cable stress .
• Tee (T-Junction) and Cross (4-Way Junction): Cut and separate wires to create branching points for multiple cable directions .
• Offset Bend (Side Shift): Adjust the tray laterally to bypass obstacles while keeping cables organized . General Rules: Always mark the bend area, maintain a smooth radius to prevent cable damage, and avoid overfilling trays at corners .

Fixing and Assembly

• Clamps and Connectors: Use mesh tray clamps or the manufacturer's connector systems to secure bends and junctions .
• Protecting Cut Ends: Bolt cutters may drag zinc coating across cut ends, forming a protective layer. Rubber caps can also be applied to prevent injury and maintain corrosion protection .
• Grounding and Bonding: Verify that all modified sections maintain proper electrical grounding and bonding to ensure safety .

Advantages of On-Site Bending

• Eliminates the need for expensive pre-fabricated fittings
• Allows seamless navigation around corners, columns, and tight spaces
• Reduces installation time and labor costs
• Maintains a clean, professional appearance in open-ceiling installations By following these methods, mesh cable trays can be customized efficiently on-site, providing flexible, safe, and professional cable management solutions for various environments.
