MF350/400 Steel Frame Roll Forming Line (Floor Joist Specialized)
MF350/400 Steel Frame Roll Forming Line is a specialized floor joist machine, focusing on continuous, high-speed and high-precision forming of floor joist profiles.
As a dedicated floor joist roll forming line, it is suitable for long-span, heavy-duty floor joists in multi-story, large-unit and commercial light steel structures, with core differences in maximum forming width and load-bearing capacity.
Key advantages: specialized profile forming (optimized for joist mechanics, one-step forming with stiffeners/web openings), high-speed stable production, one-click profile change, high precision & consistency (BIM-compatible), and cloud control (remote monitoring & fault early warning).

FAQ
What is the MF350/400 floor joist roll forming machine used for?
The MF350/400 is designed for producing long-span, heavy-duty steel floor joists for multi-story residential, modular, and commercial light steel buildings.
What floor joist profiles can the MF350/400 produce?
It produces C and U profiles, including reinforced floor joists with stiffeners and web openings. Web widths from 200 to 400 mm can be adjusted for different project requirements.
What steel thickness can the MF350/400 process?
The machine processes 1.0–2.5 mm G500 galvanized and aluminum-zinc coated steel, making it suitable for structural floor joist production.
What is the production speed of the MF350/400?
The standard machine speed reaches 35 m/min, with typical production output of approximately 400–900 m/h, depending on the profile and punching requirements.
Is the MF350/400 floor joist line fully automatic?
Yes. The line integrates decoiling, leveling, punching, roll forming, hydraulic cutting, printing, and PLC control for continuous production.
Can the MF350/400 automatically change floor joist sizes?
Yes. The machine supports one-click profile adjustment for quick switching between different floor joist widths and heights, reducing setup time between production orders.
Does the MF350/400 support BIM data?
Yes. The system is compatible with BIM and parametric design data, helping connect building design information with floor joist production. Cloud control is also available for remote monitoring, production data collection, and fault alerts.
