Output

What This Machine Produces

01

Structural C-stud sections in web widths from 70 to 300 mm — the primary load-bearing wall member in a light steel frame.

02

U-track in matching widths, for the head and base of every wall panel.

03

Floor joist members — deeper C sections in the same thickness range, used where a light steel floor deck is carried on cold-formed joists.

04

Roof truss members — the same C and U vocabulary used for roof framing in prefabricated light steel systems.

05

Swaged members — with the optional inline swage tooling, a raised dimple is formed so that a screw passes through a fixed-depth gap between nested studs, which speeds up site assembly and reduces the risk of over-driving screws.

06

Members cut and punched to a design list — where the optional design-software interface is fitted, the frame design outputs a cutting and punching list that feeds the machine control, so each member is produced automatically to the design.

07

Sections in 0.8–2.0 mm galvanised steel from G250 to G550, formed at 10–25 m/min.

Line Composition

Recommended Configuration

A complete working line, not just the forming machine. Each item below is quoted as one package.

  1. 01

    Hydraulic decoiler and straightener

    structural sections in 0.8–2.0 mm carry coil set into the finished member if it is not removed first, and a mis-straight frame member is rejected on site.

  2. 02

    LGS roll forming machine

    14–20 stations on a gearbox chain drive at 11–18.5 kW, running at 10–25 m/min.

  3. 03

    Inline swage tooling (optional)

    this is the unit that makes a light steel frame practical to assemble. Without it, every screw fixing point has to be aligned by hand.

  4. 04

    Inline service-hole and dimple punch (optional)

    punching the flat strip keeps service holes and fixing points consistently positioned along the member.

  5. 05

    Design-software interface (optional)

    accepts the cutting and punching list from LGS design software, which is the difference between running to a schedule and running to a drawing by hand.

  6. 06

    Hydraulic flying cut to length with batch counter

    frame members are many and short, so automated cut-to-list is what makes the line productive.

  7. 07

    Runout table

    long members need support along their length, not just at the cut.

How It Runs

Production Workflow

  1. 01

    Decoiler

    The coil is loaded and uncoiled at controlled tension. At 2.0 mm the coil is stiff enough that incorrect tension shows up as camber in the finished member.

  2. 02

    Straightening

    Coil set is removed before forming. On structural members this is not cosmetic: a member with residual bow will not close with the panel it is meant to receive.

  3. 03

    Service-hole and dimple punching

    When fitted, service holes and swage dimples are punched into the flat strip. Doing it flat is what keeps fixing points aligned along the member.

  4. 04

    Roll forming

    14–20 stations form the C-stud, U-track, floor joist or roof truss member progressively, in 0.8–2.0 mm galvanised steel at 10–25 m/min.

  5. 05

    Swaging

    Optional inline swage forms the raised dimple that sets the screw depth when two members nest, removing a site operation and a common source of over-driven screws.

  6. 06

    Cutting and output

    The hydraulic flying cut runs to length from the batch list, and members leave on the runout table in production sequence.

Common Questions

FAQ — Light Gauge Steel Framing Machine

What is light gauge steel framing used for?
It is used for non-combustible structural walls, floors and roofs in mid-rise residential, hotel, student and commercial buildings. It replaces timber and blockwork in many markets because it is dimensionally stable, does not rot or warp, and erects far faster on site.
What is the difference between LGS framing and stud & track?
LGS framing members carry structural load and are typically 0.8–2.0 mm thick with web widths up to 300 mm. Stud & track profiles are thinner, 0.5–1.2 mm, and are used mainly for non-structural partition walls. Both are cold-formed, but the roll tooling and the machine class differ.
Does the machine include swage dimpling for screw fixing?
Optional inline swage tooling is available. Swage creates a raised dimple so that a screw passes through a fixed-depth gap between nested studs. On site this speeds up assembly considerably and reduces the risk of over-driving screws.
Can it produce both C and U sections?
Yes. Most LGS machines run C-stud and U-track on the same base frame, either with separate roll sets or with servo width adjustment where the profile ranges overlap. Tell us your full profile schedule when ordering so we can work out the minimum cassette count.
What steel grade should be used?
G550 at 550 MPa is standard for structural members because the high yield strength allows thinner sections. G250–G300 is used for non-structural and lightly loaded members. Coating is normally Z275 or AZ150 for corrosion resistance.
Can the machine be fed by design software?
Yes, with an optional interface. Frames are usually designed in specialised LGS software that outputs a cutting and punching list; that list can feed the machine control so each member is cut and punched automatically to the design.
What is the typical output for a house frame?
A single-storey house frame in a light steel system typically needs 2–3 tonnes of sections. At 15 m/min average speed that is roughly one shift of production, including punching and swaging.
Can the machine be built for our own profile?
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.
How do we get a price for this line?
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.
What is the production speed?
Forming speed is 10 – 25 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.
How many forming stations does it use?
The line uses 14 – 20 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.
What is the drive and installed power?
Drive: Gearbox chain drive, 11 – 18.5 kW. 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.
