Which roll forming equipment is used for cable tray production?

Specialized cable tray roll forming production lines are the core equipment to manufacture various metal cable trays for power, construction and data center wiring projects, which realize fully automatic continuous cold forming from raw steel coils to finished products in one pass. The complete integrated line consists of five core functional units: hydraulic/unpowered decoiler, leveling unit, pre-punching station, multi-station roll forming host and fixed-length cutting device, all controlled by PLC+HMI servo system for synchronized operation.

Classified by finished tray styles, four mainstream dedicated roll forming machines cover full market demands:

Solid bottom & perforated cable tray roll former: Equipped with inline hydraulic punching dies to produce ventilated holes on tray base; 12–22 forming roller stands gradually bend flat strip into U-shaped trough profiles, applicable for enclosed dustproof cable trays with width adjustable from 50–600mm via cantilever roller structure.

Ladder-type cable tray roll forming machine: Split dual-set forming system, one line for C/U side rail forming, an independent auxiliary unit for cross rung stamping & automatic welding, specially for open ventilation ladder trays widely used in heavy industrial plants.

Cable tray cover roll forming machine: Matched with main tray equipment to make matching protective cover profiles, preventing cable from dust and outdoor corrosion.

Multi-size adjustable universal cable tray line: Modular cantilever design without frequent roller replacement, quickly switching different tray widths within specified range to lower mold cost for diversified orders.

Applicable raw materials include hot-dipped galvanized steel, cold rolled steel, stainless steel and aluminum sheet in 0.8–3.0mm thickness; finished trays cover solid, perforated, ladder and channel types to meet NEMA and domestic electrical industry standards.
