Connection between cable tray and flat iron

Cable trays can be securely mounted to flat iron supports using flat bar fittings, splices, and appropriate hardware to ensure structural stability and smooth cable routing.

Mounting Cable Trays to Flat Iron

Flat iron supports are commonly used as structural elements to hold cable trays in industrial and commercial installations. To connect a cable tray to a flat iron:

• Flat Bar Fittings: Use flat bar fittings such as flat splices, elbows, tees, or crosses to join cable tray sections and attach them to flat iron supports. These fittings provide smooth transitions and maintain cable alignment while distributing mechanical load evenly (TechLine Mfg.), .
• Hardware: Bolts, nuts, and washers are typically used to secure the tray or fittings to the flat iron. Ensure that the hardware is compatible with the tray material (aluminum, stainless steel, or galvanized steel) to prevent galvanic corrosion .
• Drilling and Alignment: Drill holes in the flat iron to match the tray's mounting points. Maintain proper spacing to support the tray's load class and prevent sagging or excessive stress on the cables .
• Load Considerations: Verify the tray's load rating and span distance. The flat iron support must be strong enough to carry the combined weight of the tray and cables without deformation .

Installation Tips

• Leveling: Ensure the tray is level and aligned with other sections to avoid sharp bends that could damage cables .
• Grounding: If the cable tray is metallic, ensure proper grounding to prevent electrical hazards. Flat iron supports can be bonded to the tray using grounding lugs or bonding straps .
• Corrosion Protection: Select tray and fittings with finishes suitable for the environment, such as galvanized or stainless steel, especially in humid or corrosive areas .
• Modular System: Many cable tray systems are modular, allowing easy adjustment of tray position on flat iron supports without extensive rework . By following these guidelines, cable trays can be safely and efficiently mounted to flat iron supports, ensuring both mechanical stability and proper cable management throughout the installation.
