Cable tray bent at right angle

Cable trays with right-angle bends allow smooth directional changes while maintaining cable support and capacity.

Types of Right-Angle Bends

Heavy-Duty 90° Bends: Designed for robust industrial or commercial installations, these bends are typically made from hot-dipped galvanized (HDG) steel for durability and corrosion resistance. They provide a reliable corner joint without compromising cable capacity and are suitable for 300mm or larger tray widths . Medium-Duty 90° Flat Bends: These are pre-galvanized trays used to join two sections at right angles, ideal for moderate load applications and standard electrical installations . Wire Mesh Tray Bends: Wire basket cable trays can be bent on-site using bolt cutters, allowing live adjustments for tees, crosses, risers, and reducers. Protective rubber caps or zinc layers maintain safety and corrosion resistance after cutting .

Installation Considerations

• Bending Radius: Ensure the bend radius accommodates the cable type to prevent damage, especially for thick or high-voltage cables .
• Offset Planning: For complex layouts, horizontal, vertical, or compound offsets may be required to navigate obstacles. Tools and calculators can help determine the correct sloped section length and cut marks for precise installation .
• Mounting: Cable trays can be mounted on floors, walls, ceilings, or equipment racks. Heavy-duty bends often require threaded rods, nuts, and washers for secure suspension .
• Material and Finish: Choose galvanized steel for corrosion resistance, or powder-coated finishes for aesthetic or environmental considerations .

Practical Tips

• Use gradual bends (15°–30°) for thick or stiff cables to ease pulling and reduce stress.
• Reserve sharp 45°–60° bends for confined spaces where minimal horizontal run is available .
• Ensure all bends and offsets maintain continuous cable support to prevent sagging or strain. By selecting the appropriate bend type and planning offsets carefully, cable trays can efficiently navigate corners and obstacles while maintaining cable integrity and system reliability.
