Steel sheet pile is the foundation material that holds back earth and water: interlocking sections driven into the ground form retaining walls with watertight joints on both edges. It is used across port, river, canal and underground foundation work. The profile is demanding — the interlock has to mate perfectly in the ground — and that is what shapes the machine you should buy.
1. The interlock is the product
Every sheet pile section carries an interlocking joint on each edge, and the wall only works if every joint mates. That is why our sheet pile line uses 30 forming stations — more than any other line in our range — dedicated to getting the lock profile exact, on every piece, all day. When you compare quotations, compare station count on the lock stations first.
2. Material and gauge
The line runs carbon steel coil. Sheet pile is a structural product: the gauge and grade come from the engineering design of the wall, so agree the section and the coil spec before the machine is finalized.
3. Line configuration
The complete line: hydraulic decoiler (heavy coil handling from the start), main roll forming machine, cutting machine, outer table, hydraulic system and PLC control. Nominal forming speed is 0–15 m/min — slower than a channel line, by design, because the joint tolerances come before raw speed.

| Material | Carbon steel coil |
| Decoiler | Hydraulic |
| Rollers / frame | Cr12Mov, casting frame, gearbox drive |
| Control | Delta PLC, Yaskawa inverter |
What drives the price of a sheet pile line
At 8.0–14 mm, sheet pile is the heaviest coil on this site, and the machine is built around that. Four items set the price:
- Coil thickness — 14 mm needs heavier stands, larger bearing journals and more drive torque than 8.0 mm, and the difference is structural rather than cosmetic.
- Station count — 30 stations on this configuration, because thick coil springs back after every pass and has to be brought to shape gradually.
- Interlock precision — the lock geometry is what makes the pile drive and seal, so roll tolerance and the number of finishing stations are quoted against the interlock specification.
- Punching and coil handling — hole scope per section, and a hydraulic decoiler sized for the coil weights you buy.
Send the section drawing with the interlock detail, the steel grade, the coil weight and the line speed you need. The station layout follows from the section, and the quotation states the interlock tolerance the line is built to.
