1. Definition
This page maps the shared process spine for steel scaffold walking-board (plank) roll forming: coil handling, optional punching or embossing, progressive forming, and cut-to-length. Equipment pages keep the locked m/min and kW figures; this entry explains where those figures attach on the shop floor.
2. Common sequence
- Decoil (often ~5 t class)
- Level / straighten
- Servo feed when a punch station is present
- Punch, stretch-hole, emboss, and/or end-notch as specified
- Roll form the plank section
- Cut-to-length — stop shear or tracking / flying cut
- Exit table / roller collect (optional stack)
Public walkboard explainers list the same seven-station idea (decoil → level → servo → punch → form → cut → exit). Treat them as industry context; station names and options still follow the named proposal.
3. Configuration forks
| Configuration | Process emphasis | Speed story (equipment pages) |
|---|---|---|
| C225 / YX38-225 | Punch stretch holes → form → hydraulic cut | About 5–10 m/min recommended |
| Punched + tracking (GY160 class) | Continuous press punch → form → tracking cut | About 1–6 m/min |
| Hanging / hoist-change multi-profile | Punch + hydraulic end notch → dual hanging formers → reshape / cut | CN with punch about 8–12; some RU sheets about 5 — do not lock one |
| Dual-width spacer boards | Punch → form; width change by spacers | About 6–10 m/min on that sheet |
4. Reference checkpoints
| Checkpoint | What to confirm |
|---|---|
| Punch before form? | Hole map / emboss / end notch drawings |
| Cut mode | Stop shear vs hydraulic tracking / flying |
| Changeover | Fixed roller set, spacer kits, or whole hanging frame swap |
| Power split | Forming host vs punch vs hyd vs installed total — never merge labels |
Speeds and kilowatts stay on the equipment encyclopedia pages for each configuration. This flow page does not re-lock them.
5. Boundaries and conflicts
- Not every plank market requires punching — embossed or plain boards are valid product choices.
- English “floor decking” on a hanging walking-board BOM is still a plank plant, not a structural floor-deck line.
- ERW scaffold tube is a different process family entirely.
- Do not average competitor catalog speeds (often 8–20 m/min without matching punch density) into one invented ZTRFM band.
6. Buyer FAQ
Must every scaffold plank line punch?
No. Some markets use embossed or plain boards. Punched anti-slip and drainage is a configuration choice driven by the finished drawing.
Where does tracking cut sit in the flow?
After forming, as a flying / tracking hydraulic cut synchronized with strip speed. It replaces a simple stop-shear package when that option is selected.
Why do hanging lines add an end-notch station?
Multi-profile hanging plants often punch head/tail notches (and sometimes logo or connection holes) before the strip enters the hanging former.
Can I compare only “forming stands” across vendors?
Not usefully. Punch density, cut mode, and changeover hardware dominate cycle time and power more than stand count alone.
