C Wall Stud / Partition Keel Roll Forming Line

1. Definition

A C wall stud / partition keel roll forming line produces light-gauge C studs for gypsum drywall partitions.

It is not a U-track-only mill, not a CU combined mill, not a villa frame mill, and not a structural C purlin mill.

2. Typical process flow

1. Decoil
2. Guide / feed
3. Optional hydraulic punching
4. Roll form the C stud
5. Hydraulic cut-to-length
6. Exit

3. Technical parameters (C50/75/100 class)

4. Other configuration tiers

• 65C with holes — forming about 20 m/min, with punch/shear about 10 m/min; main about 3 kW; hydraulic about 5.5 kW; shaft about φ40 mm; about 10 stands; thickness about 0.4–0.8 mm; host about 3300 × 800 × 1400 mm / ~3 t
• Single-size 35/65/70, marking, and high-speed site configs — confirm per proposal; do not treat site “high-speed” cases as the only public speed

Market multi-size 50/75/100 pages often advertise spacer or servo width change — industry context aligned with the multi-size concept above.

5. Related machines

• U track line (U50/75/100)
• CU combined stud-and-track
• Villa LGS frame (thicker, assembly punches)
• Structural C purlin

6. Inquiry checklist

• Target sizes (C50/75/100 vs single-size vs 65C)
• Thickness / yield-strength band and hole layout drawings
• Whether a matching U track or CU combined mill is also required
• Confirm not villa C140 or structural purlin duty

7. Buyer FAQ

Does multi-size need full roll replacement?

On the C50/75/100 reference, width change is by spacers, with matching cutters — see the multi-size encyclopedia entry.

Same as villa C140?

No. Villa frames use thicker strip and multi-station assembly punching.

Is the 65C with-hole package the same rating?

No. It uses a different shaft, pass count, and power tier — confirm that scheme on the proposal.
