PUTAI C89 C140 Light Gauge Steel Frame Machine – Automatic C Stud & Track Roll Forming Line

What Is The Light Gauge Steel Framing Roll Forming Machine?

A light gauge steel frame machine, also called a steel stud framing machine or an LGS roll former, is industrial equipment that cold-forms thin galvanized strip, typically 0.5 mm to 2.0 mm thick, into structural C sections, U tracks and custom profiles through a sequence of contoured roll passes. Because the steel is formed at room temperature, the zinc coating is not burned away and the section gains yield strength through cold work. The result is a framing system that is dimensionally stable, termite-proof, rot-proof and non-combustible, with a strength-to-weight ratio that hot-rolled sections cannot reach at the same mass.

C89, an 89 mm web with a 41-45 mm flange and a 10-12 mm lip, is the industry standard for internal partitions and load-bearing studs in low-rise residential units. C140, a 140 mm web with a 50 mm flange, is the section specified for external walls, floor joists and roof trusses, where spans are longer and loads are higher. Covering both sizes on a single C89 C140 roll forming machine removes the need for a second capital investment and lets you quote a far wider range of projects, from a single-family light steel villa to a six-storey modular residential block. Standardising on one steel stud framing machine for both sections also means one coil width, one tooling set and one spare-parts list.

The light gauge steel frame machine supports a wide range of profile widths, making it adaptable to residential wall framing, roof trusses, floor joists, and modular building components. The dual-head uncoiling system enables seamless coil switching without production downtime, while the flying punching and cutting devices operate in motion to maintain continuous high-speed output.

Applications

This light gauge steel frame machine is purpose-built for:

1. Residential wall framing (studs and tracks)

2. Roof trusses and purlins

3. Floor joist and ceiling systems

4. Modular and prefabricated building components

5. Light commercial and industrial construction

6. Drywall framing and interior partition systems

The machine’s output supports 1–6 level residential, modular, and transportable unit construction, as well as light commercial projects requiring consistent, code-compliant cold-formed steel framing。

Why Choose This Machine

Light gauge steel offers an exceptional stiffness-to-weight ratio — averaging 20–30 kg of steel per square meter — enabling structures that support expansive designs without heavy foundations。This machine capitalizes on that advantage by producing profiles that reduce concrete usage by up to 25%, lowering both material costs and environmental impact.

The integrated automation allows a single operator to manage the entire production process, from coil loading through to finished, labelled components. Pre-punched fastening holes, dimpled connections, and individually labelled components eliminate guesswork on-site and accelerate assembly。

With built-in design software compatibility (DXF/CSV import), the machine bridges the gap between architectural blueprints and factory production, ensuring every light gauge steel frame machine output meets project specifications with minimal material waste.

FAQ

1. What software is compatible with this light gauge steel frame machine?

The machine directly supports design output files from major light steel framing software suites, including Vertex BD, FrameCAD, MWF (StrucSoft), and Scottsdale format (.csv and .txt).

2. What thickness and grades of steel coil can the production line process?

Our cold formed steel framing production line reliably handles hot-dip galvanized and Galvalume steel coils with thicknesses from 0.8 mm to 1.20 mm and tensile yield strengths from G300 up to G550.

3. What is the daily output capacity of the light steel framing roll forming machine?

Operating at speeds of 30 to 50 meters per minute with continuous flying shearing, a single 8-hour shift produces between 12,000 and 18,000 linear meters of framing profiles.
