JX Roll Forming provides Sheet Pile Profile Forming Solutions. The overview below covers profiles, specifications and selection logic.
A steel sheet pile roll forming machine forms U or Z sheet pile sections from 8.0–14 mm carbon steel coil at 0–15 m/min. This line runs 30 forming stations on a cast frame with Cr12MoV rolls, a hydraulic decoiler and gearbox drive, punching and cutting in line under Delta PLC control. Delivery is 85 days, and more than 80 lines are in service.
Thick coil does not bend cleanly in a few passes. At 8.0–14 mm the strip springs back after every pass, so the section is brought to shape gradually over 30 stations rather than forced to final form in a short roll train. More stations also spread the bending load, which keeps residual stress in the section lower and holds the interlock geometry where the design puts it.
This is the main structural difference between a sheet pile line and a light gauge channel line: the same nominal profile formed from 2.0 mm coil takes a fraction of the stations that 14 mm requires.

The section is built to your drawing. U and Z profiles differ in how the interlock is arranged and in the number of bends the roll train has to make, so the roll set is specified per project against the section drawing and the required interlock tolerance. Send the section drawing with the coil grade and the line speed you need, and the station layout is worked out from that.
An engineer can travel to your plant for installation and commissioning. The line carries service for its working life, and quality problems not caused by operator error are handled under that commitment. More than 80 sheet pile lines have been built and shipped to customers in China and overseas.
Q: What coil thickness does the line run?
A: 8.0–14 mm carbon steel coil with yield strength 250–550 MPa and tensile strength G350–G550.
Q: What is the forming speed?
A: 0–15 m/min nominal. Actual output depends on the hole pattern, because punching stops the line.
Q: How many forming stations are needed?
A: 30 stations on this configuration — the station count follows from the coil thickness and the section drawing.
Q: What is the delivery time?
A: 85 days after contract confirmation.
