Light gauge steel framing machine LGF300 (C300, T: 1.2-2.2mm) is a fully automatic floor joist/ground beam special roll forming machine and more efficient for mass production of floor systems in prefabricated houses.
It adopts a fully automated process: hydraulic uncoiling → leveling → punching → roll forming → cutting → discharging.
It is specially designed for continuous cold bending of G550/G300 galvanized or Zn-Al-Mg steel strips to produce C-shaped floor joists and ground beams up to 300mm wide, suitable for floor systems in prefabricated residential and light commercial buildings.

FAQ
What does the LGF300 light gauge steel floor joist machine produce?
The LGF300 produces C-shaped floor joists and ground beams up to 300 mm wide for prefabricated residential, modular, and light commercial buildings.
What material thickness can the LGF300 process?
The machine processes 1.2–2.2 mm G500 galvanized or aluminum-zinc coated steel for light gauge steel floor systems.
What is the production speed of the LGF300?
The standard machine speed reaches up to 35 m/min, with typical output of about 400–900 m/h depending on the profile and punching requirements.
Is the LGF300 fully automatic?
Yes. The line integrates hydraulic decoiling, leveling, punching, roll forming, cutting, and discharging in one continuous production process.
What punching operations can the LGF300 perform?
The machine supports lip cuts, service holes, bolt holes, web notches, chamfer cuts, swages, dimples, and shearing, with punching accuracy up to ±0.5 mm.
Can the LGF300 connect with BIM or production management software?
Yes. It supports BIM software connection, CSV data import, and MES cloud functions for remote monitoring, production statistics, and fault alerts.
