Imperial Metal Stud Roll Forming Machine

3-5/8in (92 mm) web depth, 25 mil or 33 mil gauge, is by far the most common size for interior partition walls in North American commercial construction. The 3-5/8in stud fits within a 3-1/2in nominal wall dimension when inserted into tracks, giving the standard 4in partition wall thickness used in most office fit-out. The machine produces this size as its primary output with the other sizes available by width adjustment.

25 mil (24 gauge, approximately 0.635 mm) is the minimum gauge for non-structural interior partitions per AISI S220. 33 mil (20 gauge, approximately 0.838 mm) is the standard for exterior walls and tall interior partitions. The machine runs both gauges from the same tooling set -- the roll gap is adjusted for the material thickness.

Hat channel (resilient channel, RC-1, or cold-rolled furring channel) is a different profile from a C-stud -- it has a hat-shaped cross-section used for ceiling and wall furring. A dedicated hat channel tooling set is needed. We can supply both the stud/track line and a hat channel line as a two-machine package, or as separate orders.

The Imperial Metal Stud Machine on this page is configured for the non-structural partition range (25-33 mil). For structural applications requiring 54 mil (16 ga) to 97 mil (12 ga) and AISI S240 compliance, see the AISI Light Gauge Steel Framing Machine -- it covers the full structural range with a heavier-duty drive.

The standard 10 ft (3,048 mm) auto-cut matches the standard stud length used in North American construction for 9 ft or 10 ft floor-to-ceiling heights. The control allows any cut length to be programmed -- 8 ft, 10 ft, 12 ft and custom lengths are all available without tooling change.

A well-set partition stud line in 25-33 mil gauge runs at 25-50 m/min forming speed. Practical shift output at 80% uptime is approximately 8,000-15,000 linear metres per 8-hour shift depending on cut length. For very high volume (above 20,000 m/shift), a flying-cut high-speed line is more appropriate.

Yes. Send the profile drawing with the section dimensions, the material and thickness, and the coil width you intend to run. We confirm the roll design, forming stations and line layout against that drawing before quoting, so the machine matches the section you actually sell.

Send the profile drawing or section dimensions, the material and thickness, the coil width, and your target output per shift. Price depends on the profile, the coil and the level of automation, so we quote against your actual job rather than a catalogue figure.

Material thickness runs 25 mil (0.635 mm) to 33 mil (0.838 mm) -- non-structural partition range. The roll gap, drive and cutting unit are set for this range, so staying inside it is what keeps the section geometry repeatable run after run.

Forming speed is 25-50 m/min. Treat this as the line speed: real shift output also depends on cut length, coil reloading and how often the profile is changed.

The line uses 14-18 forming stations. Station count follows the section — more bends and tighter tolerances need more forming steps, which is why two profiles rarely share one roll set.

Drive: Gearbox or chain. Final drive sizing is confirmed against your profile and coil, because a wider or thicker section needs more torque to hold the same line speed.
