How to make the flared end of a ladder-type cable tray

To create a flared end on a ladder-type cable tray, carefully cut, bend, and shape the tray using appropriate tools while ensuring edge protection and structural integrity.Step-by-Step Process1. Material Selection Choose the appropriate material for your ladder tray based on the environment. Cold-rolled steel is suitable for general applications, while stainless steel is preferred for corrosive conditions . Ensure the tray section is compatible with the intended cable load. 2. Cutting the Tray Mark the section where the flare will begin. Use a band saw or CNC laser cutter for precision cuts, minimizing burrs and swarf . Always wear PPE, including Kevlar gloves, eye protection, and headgear, as cut edges can be sharp . 3. Bending and Forming the FlareUse a bending machine or press brake to gradually widen the tray end.For ladder-type trays, you may need to cut the side rails at intervals to allow controlled outward bending without deforming the rungs .Ensure the flare is symmetrical and matches the required width for cable entry. 4. Edge Protection After forming, remove any burrs and sharp edges using a file or deburring tool. For wire mesh or perforated trays, consider rubber or plastic end caps to protect cables and installers . 5. Assembly and Reinforcement If the flared end is part of a modular system, use splice plates and bolts to attach it securely to the main tray section . Check that the flare maintains structural integrity and can support the cable load. 6. Surface Treatment Apply any necessary galvanization or powder coating to protect the flared end from corrosion, especially if the tray will be exposed to moisture or chemicals .Tips and Safety ConsiderationsAlways follow manufacturer guidelines for bending radii and maximum flare width.Work slowly and check alignment frequently to avoid permanent deformation.Use proper lifting and support techniques to prevent injury when handling long tray sections.Verify that the flared end does not interfere with adjacent fittings or supports in the cable tray network . By following these steps, you can produce a safe, functional, and durable flared end for a ladder-type cable tray suitable for cable entry or transition points.
