How to install an aluminum trough cable tray on a metal structure?

Jun 17, 2025

Installing an aluminum trough cable tray on a metal structure is a task that requires careful planning, the right tools, and proper techniques. As a leading supplier of Aluminum Trough Cable Trays, I have witnessed firsthand the importance of a well - installed cable tray system for efficient cable management. In this blog, I will guide you through the step - by - step process of installing an aluminum trough cable tray on a metal structure.

Pre - installation Preparation

Before you start the installation process, it is crucial to conduct a thorough site assessment. First, measure the area where the cable tray will be installed. Ensure that the metal structure can support the weight of the cable tray, cables, and any future expansions. Check for any obstacles such as pipes, ducts, or other equipment that may interfere with the installation.

Next, gather all the necessary tools and materials. You will need a tape measure, a level, a drill, drill bits suitable for metal, a wrench set, cable ties, and of course, the aluminum trough cable tray and its associated accessories such as brackets, elbows, and tees. Make sure all the components are in good condition and match the specifications required for your project.

Selecting the Right Cable Tray

As an Aluminum Trough Cable Tray supplier, I understand that different projects have different requirements. Aluminum trough cable trays are known for their lightweight, corrosion - resistant properties, making them ideal for a variety of environments. However, depending on your specific needs, you may also consider other types of cable trays such as the Stainless Steel Channel Calbe Tray, which offers higher strength and durability in more demanding conditions, or the Powder Coated Trunking Cable Tray and Powder Coated Trough Cable Tray, which provide an additional layer of protection against corrosion and a more aesthetically pleasing finish.

Mounting the Brackets

The first step in the actual installation is to mount the brackets on the metal structure. Mark the positions of the brackets along the path where the cable tray will be installed. Use a level to ensure that the marks are straight and at the correct height. Drill holes into the metal structure at the marked positions, taking care not to damage any internal components of the structure.

Insert the appropriate fasteners, such as bolts or screws, into the drilled holes and attach the brackets firmly. Make sure the brackets are evenly spaced to provide adequate support for the cable tray. The spacing between brackets typically depends on the width and load capacity of the cable tray, but a general rule of thumb is to space them no more than 3 - 4 feet apart for most applications.

Assembling the Cable Tray

Once the brackets are in place, it's time to assemble the aluminum trough cable tray. Start by laying out the sections of the cable tray on the ground near the installation site. Connect the sections using the provided connectors or by welding if necessary. Ensure that the joints are tight and secure to prevent any movement or misalignment.

If you need to make bends or turns in the cable tray, use the appropriate elbows and tees. These accessories are designed to fit seamlessly with the main cable tray sections, allowing for a smooth and continuous cable path. Make sure to align the holes in the accessories with those in the cable tray sections before fastening them together.

Installing the Cable Tray on the Brackets

Carefully lift the assembled cable tray and place it onto the brackets. Make sure the cable tray is centered on the brackets and sits evenly. Use a level to check the horizontal and vertical alignment of the cable tray. If necessary, adjust the position of the brackets or the cable tray to achieve a proper alignment.

Secure the cable tray to the brackets using the appropriate fasteners. Tighten the fasteners firmly, but be careful not to overtighten them, as this could damage the cable tray or the brackets. Once the cable tray is securely attached to the brackets, check for any signs of movement or instability.

Running the Cables

After the cable tray is installed, you can start running the cables through it. Begin by organizing the cables according to their type, size, and function. Use cable ties to bundle the cables together at regular intervals to prevent them from becoming tangled.

Feed the cables into the cable tray, starting from one end and working your way to the other. Make sure the cables are laid out neatly and do not cross over each other. Leave enough slack in the cables at the ends for future maintenance and repairs.

Grounding the Cable Tray

Proper grounding is essential for the safety and functionality of the cable tray system. Connect the cable tray to a suitable grounding source using a grounding conductor. This helps to protect the cables and the equipment connected to them from electrical surges and faults.

Make sure the grounding connection is secure and meets all relevant electrical codes and standards. Check the continuity of the grounding system using a multimeter to ensure that it is functioning properly.

Testing and Inspection

Once the installation is complete, conduct a thorough testing and inspection of the cable tray system. Check for any loose connections, damaged components, or signs of wear and tear. Verify that the cables are properly installed and functioning as expected.

Test the electrical continuity of the cables and the grounding system. Look for any signs of overheating or abnormal electrical activity. If any issues are detected, address them immediately to prevent potential problems in the future.

Maintenance

Regular maintenance is crucial to ensure the long - term performance of the aluminum trough cable tray. Inspect the cable tray periodically for signs of corrosion, damage, or loose connections. Clean the cable tray to remove any dirt, dust, or debris that may accumulate over time.

Check the cables for any signs of wear or damage, and replace any damaged cables as soon as possible. Make sure the grounding system remains intact and functioning properly. By following these maintenance procedures, you can extend the lifespan of your cable tray system and ensure its reliable operation.
