Full process diagram of mesh cable tray construction

The mesh cable tray manufacturing process involves sequential steps from raw material selection to final quality inspection, including cutting, welding, forming, bending, and finishing.Step-by-Step Manufacturing Flow1. Material SelectionChoose high-quality steel or stainless steel based on environmental conditions (indoor/outdoor).Decide on surface finish: galvanized, hot-dip galvanized, or powder-coated for corrosion resistance . 2. Decoiling and LevelingMetal coils are unrolled and leveled to remove curvature and ensure flatness for accurate processing . 3. Wire CuttingCut longitudinal and cross wires to required lengths using laser cutting or shearing machines .Ensure precision to minimize material waste. 4. Wire FeedingLinear feeding: straight wires are fed into the welding system via a servo-controlled trolley.Horizontal wire feeding: cross wires are positioned in the blanking system for precise placement . 5. Welding / Mesh FormationAutomatic welding machines join longitudinal and cross wires at intersections.Two mesh panels can be welded simultaneously to form the cable tray panel . 6. Mesh Panel Bending / FormingWelded mesh panels are placed in bending machines to achieve the desired tray profile (U-channel, C-channel, or ladder type).Secondary bending may be performed on a press brake for precise angles . 7. Punching / Perforation (Optional)Holes or slots are punched for mounting, ventilation, or cable access using hydraulic punch machines . 8. Surface FinishingApply protective coatings such as powder coating or galvanization to enhance durability and corrosion resistance . 9. Quality InspectionInspect raw materials, in-process mesh, and finished trays for dimensional accuracy, weld integrity, and surface finish . 10. Packaging and DispatchFinished cable trays are packaged according to size and type, ready for shipment or installation . This flowchart ensures efficient, high-quality production of mesh cable trays suitable for industrial, commercial, and residential electrical installations, while maintaining flexibility, ventilation, and durability .
