Cable tray roll forming machine
PUTAI's cable tray roll forming machine is a continuous line that forms cable support trays from coiled steel strip — perforated, ladder, trough and channel profiles — without material removal. It runs pre-painted galvanized, galvanized, aluminium and stainless strip from 0.7 mm to 1.2 mm.
A cable tray roll former is not one machine but a sequence: decoiler, entry guide and leveling, 22 forming stations, in-line hydraulic punching, flying cut-off, and a PLC that repeats the same length and hole pattern every cycle. One cable tray making machine of this type replaces a press line, a separate punch and a shear.
Tray Types This Line Produces
Four tray families share the same line platform. Each profile needs its own roll set — that changeover decides whether one line covers your full range.
1. Perforated tray. Base and side walls punched in-line, so ventilation slots and tie-down holes are formed in the same pass. The usual choice for data and communication cabling.
2. Ladder tray. Two side rails joined by rungs, formed from the same strip. Highest strength-to-weight ratio, used for heavy power runs.
3. Trough, channel and wire mesh tray. A solid base with raised side walls for full containment where cable must be protected from dust, water or impact; the wire mesh variant uses a grid structure for heavy cables where weight matters.
How the Line Is Built, Station by Station
1. Decoiler, entry guide and leveling. The decoiler holds the coil and feeds strip at controlled tension; the guide and leveling unit flattens and aligns it. Under-sizing this unit is the usual cause of twist and camber in finished tray.
2. Roll forming stations. 12 stations of machined rolls, each taking a small forming step. Graduated nuts set the roll gap precisely, which holds the profile dimension over a long run.
3. In-line punching and notching. A hydraulic unit punches holes, notches and slots while the strip moves, so perforation is not a second operation.
4. Flying cut-off. The shear travels with the strip and cuts without stopping the line, leaving a burr-free end. Blade material is Cr12.
5. PLC control. The operator sets length, quantity and hole pattern; the controller repeats them every cycle.

Cable tray is a bracket system for managing cables and lines. It is made of steel, aluminum or plastic to facilitate the spread and maintenance of power such as wires, cables, signal lines and other circuits in industry or construction.

Punching and Perforation Options
Perforation is where most cable tray quotes differ. Here the hydraulic punching unit sits between forming and cut-off, so holes and notches are made while the strip moves.
Three things are fixed at order stage: the hole pattern, the notch position on the side wall, and the spacing pitch. Because the PLC holds the pattern, several hundred pieces keep the same hole position — which matters when trays are joined on site and splice plates must line up.
If your range covers perforated and solid tray, the punching unit can be disengaged and the line runs as plain forming and cutting.
Customization and Optional Equipment
Rolls are machined from Cr12 (D3) high-carbon high-chromium steel, chosen for wear resistance rather than cost. Shafts are forged and heat-treated, and drive is by gearbox rather than chain — which holds accuracy at higher speed with less maintenance.
Full-auto size adjustment repositions the forming rolls without manual shimming, and graduated nuts make each setting repeatable after a changeover.
Optional and quoted separately: additional roll sets for a second profile, a packing machine, and custom paint colour.
Why Buy a Cable Tray Line from PUTAI
PUTAI builds cold roll forming lines in Tianjin, China, and has supplied cable tray, drywall profile, ceiling and rack lines to buyers across Africa, the Middle East, Central Asia and South America. Minimum order is one set, so a first line for a new plant needs no volume commitment.
Before shipment the line is assembled and run with your strip; hole pattern and cut length are checked against your drawing. Engineers handle after-sales service and a 12-month warranty applies.
Factory visits are welcome — nearest airports are Beijing Daxing and Tianjin.
FAQ: Cable Tray Roll Forming Machine
1. Can one line make both perforated and ladder tray?
Yes, but each profile needs its own roll set; the line and punching unit stay the same.
2. What strip thickness can the line run?
0.4 mm to 0.6 mm cold-rolled strip, in pre-painted galvanized, galvanized, aluminium or stainless steel.
3. Is the perforation done in-line or as a second operation?
In-line. The punching unit sits before the cut-off, so holes and notches are formed in the same pass. No separate press.
4. What is the minimum order quantity?
One set. A single line for a new plant is accepted.
5. What are the payment terms?
30% T/T deposit in advance, 70% balance before shipment.
6. Do you provide installation and training?
Engineers are available for after-sales service; tell us the site when ordering and the visit is scheduled with the shipment.
