Cable tray tee bend fabrication

Cable tray tee bends can be fabricated on-site or in the workshop using cutting, bending, and joining techniques to create a T-junction that maintains cable support and structural integrity.Materials and Tools RequiredMaterials: Galvanized steel sheets (commonly 1.6 mm thick), wire mesh trays, or ladder tray sections depending on the system design .Tools: Measuring tape, marker or scriber, bolt cutter or metal shear, angle grinder, drill machine, rivets or nuts & bolts, pliers, hand gloves, and bending tools such as a manual bender or hydraulic press brake .Optional: Welding machine for permanent joints and rubber caps to protect cut ends in wire mesh trays .Step-by-Step Fabrication Process1. Marking the Tee BendDetermine the location and angle of the tee (commonly 90°).On the flat tray section, mark the centerline and side edges of the main tray and the branch section.Divide the bend area into equal segments to ensure a smooth curve .2. Cutting the TrayFor wire mesh trays, use a bolt cutter to cut the mesh where the branch will join, ensuring the protective zinc layer remains intact .For solid or ladder trays, cut triangular or rectangular sections on the side walls to allow bending and forming of the branch .3. Forming the TeeBend the tray sections gradually using a manual bender or press brake to achieve the required T-shape.Ensure uniform bending to maintain cable support and structural integrity .4. Joining the SectionsRejoin cut edges using rivets, nuts & bolts, or welding for reinforcement.For wire mesh trays, additional metal strips or rubber caps can be used to protect cut ends and maintain safety .5. Drilling and AssemblyDrill holes at the ends of the tee bend for connection to straight tray sections.Assemble the tee into the main cable tray run using nuts and bolts, ensuring proper alignment and support .Safety and Quality ConsiderationsAlways wear hand gloves and safety gear when cutting and bending metal trays.Maintain minimum bend radius to prevent cable damage.Ensure structural stability by reinforcing joints and checking alignment before installation .For corrosive environments, use stainless steel or coated trays to prevent rust and maintain durability .SummaryFabricating a cable tray tee bend involves careful marking, cutting, bending, and joining of tray sections. Wire mesh trays allow on-site modifications with simple tools, while ladder or solid trays may require press brakes and welding. Following proper procedures ensures safe, durable, and professional cable routing in electrical installations .
