Cable tray fixings are the mechanical components used to secure cable trays to supports, structures, or building surfaces, ensuring stability, load safety, and long-term reliability.

Main Types of Cable Tray Fixings

1. Suspension Fixings (Overhead Support)
Used to hang trays from ceilings or roof structures.
Threaded Rod (All-Thread) & Strut Channels: The most common system.
Components: Threaded rod (M8, M10, M12 are common), nuts, washers, and beam clamps or channel nuts within a strut channel (Unistrut-type). Allows for easy height adjustment and is very versatile.
Cable Tie Hangers & Steel Strapping: Used for lighter trays or in telecom/data applications. Must be rated for the load and be non-corrosive.
Drop Rod Hooks: For hanging ladder tray directly from ceiling wires or steel purlins.

2. Wall Mount Fixings
Used to attach trays to vertical walls or structural columns.
Cantilever Arms (Wall Brackets): Brackets fixed to the wall with a horizontal arm supporting the tray. Can be single or double-sided.
Flange Brackets (End/Corner Brackets): Used to terminate a tray run at a wall or change direction from horizontal to vertical.
J-Bolts or Through-Bolts: For securing the tray side rail directly to a concrete or steel column.

3. Fixings to Structure
The method of attaching the support component (like a rod or bracket) to the building is critical.
Concrete:
Anchor Bolts: Chemical anchors (resin) or mechanical anchors (wedge, sleeve, drop-in) are the strongest and most common for heavy loads.
Concrete Screws: For lighter loads, faster installation.
Steelwork:
Beam Clamps: Wrap around the flange of an I-beam or H-beam. Choose a model that doesn't require drilling.
C-Clamps / Girder Clamps: Similar to beam clamps.
Drilled and Tapped: Drilling through the steel and using a bolt and nut. Provides the strongest connection but is invasive.
Masonry/Brick:
Heavy-Duty Wall Plugs & Bolts: Requires careful selection based on the brick type and potential for cracking.

Key Functions

• Secure cable trays to support systems

• Maintain correct tray alignment and spacing

• Transfer cable load safely to the structure

• Prevent vibration, movement, and deformation

Common Types of Cable Tray Fixings

• Bolts & Nuts – tray-to-support and tray-to-tray connection

• Spring Nuts / Channel Nuts – used with strut channels

• U-Bolts – fixing trays to round pipes or beams

• Beam Clamps – drilling-free fixing to steel structures

• Wall Plugs / Anchor Bolts – concrete wall or ceiling installation

• Tray Couplers / Splice Plates – join tray sections

• Hold-Down Clamps / Clips – prevent uplift or lateral movement

Materials & Surface Finish

• Materials: Carbon steel, stainless steel (SS304 / SS316)

• Surface treatment:

  • Electro-galvanized (indoor use)

  • Hot-dip galvanized (industrial / outdoor)

  • Stainless steel (high corrosion environments)
