Typical Process Flow of a C Wall Stud Line

1. Process purpose

A C wall stud / drywall partition keel line continuously forms galvanized strip into light-gauge C studs for gypsum-board partitions, optionally with service holes, then cuts them to length. This page is a process map — locked speed, kW, and station counts stay on the machine / multi-size entries and the named technical proposal.

It is not a U-track-only route, not a CU combined changeover story, and not a villa LGS frame assembly-punch route.

2. Route steps

A common documented sequence is:

1. Uncoiling — coil on a manual or powered decoiler
2. Feeding / guiding — strip enters the forming section
3. Optional hydraulic punching — hole layout per drawing when fitted
4. Roll forming — progressive passes create the C section
5. Hydraulic cut-to-length — length cutting; cutter change is common when stud width changes
6. Exit / stacking — simple exit table or stacking by configuration

3. What each station does

• Decoiler — presents strip at a steady feed; capacity follows the proposal
• Guide / feed — keeps strip centered before punch or first forming pass
• Hydraulic punch (optional) — service / utility holes; skip when drawings have no holes
• Roll stands — about 12–14 stations and shaft about φ50 mm on the C50/75/100 class reference (other configs differ)
• Hydraulic shear — stop-cut to ordered length
• Controls — gear drive with PLC / HMI / inverter class on the recommended reference

4. Multi-size changeover

Multi-size C50 / 75 / 100 setups typically change width with spacers and matching cutters between batches — not a full stand rebuild. When a published speed already includes punch and cut time, do not read it as pure forming speed.

5. Speed and power context

Process pages must not invent a single “standard stud speed.” Use these as context only, then lock values on the proposal:

• Working speed about 15–20 m/min on the recommended C50/75/100 reference
• Forming main about 5.5 kW; hydraulic about 5.5 kW on that same reference
• Thickness about 0.4–0.6 mm on that reference (other configs may list a wider band)

Compare production speed only with the same punch-on / punch-off choice.

6. Related processes

• U track line — separate route for partition tracks; often no in-line punch
• CU combined line — same partition system, but C↔U changeover is part of the process story
• Villa LGS frame — multi-station assembly punching before / with forming; thicker strip
• Furring / hat channel — secondary profiles; different roll path

7. Inquiry checklist

• Stud drawing (web / flange / lip) and hole map if any
• Whether punch is required in-line
• Single size vs C50/75/100 multi-size
• Thickness, grade, and hardness band
• Cut length range and stacking preference

8. Buyer FAQ

Is punching always required?

No. Hydraulic punching is optional unless the stud drawing requires holes.

Does multi-size mean rebuilding the mill each batch?

No. The C50/75/100 class reference changes width with spacers and matching cutters — confirm the procedure on the proposal.

Can I reuse a villa frame punch map on drywall studs?

No. Villa lines use multi-station assembly hole systems on thicker strip. Keep punch layouts separate.

Where do speed and kW live?
