Light steel frame roll forming machinery produces cold-formed steel structural framing studs and tracks for building construction from coiled sheet metal in an automated process. This comprehensive guide covers different types, working principles, capabilities, pricing, suppliers, operations and more for these important metal processing lines.
Overview of Light Steel Frame Roll Forming Machines
Roll forming machines that shape light gauge steel into C-studs, U-channel tracks, trusses and custom profiles for structural framing support offer versatility, efficiency and precision unmatched by other techniques. Key capabilities include:
- High productivity from automated forming at over 30ft/min
- Cold formed stud widths from 50mm to 300mm
- Material thickness from 18 gauge to 22 gauge
- For wall systems, roof trusses, solar mounts etc.
- Superior strength-to-weight ratio
- Custom profiles programmed through tooling
- Easy to install modular construction
- Recyclable, sustainable green building material
Light steel gives structural integrity to commercial and residential buildings with its high strength reinforcing properties. Pre-formed modular framing accelerates safe construction. The roll forming process enables mass production of studs.
Types of Light Steel Frame Roll Forming Machines
| Type | Description |
|---|---|
| Portable | Compact movable units with 1-3 forming heads for small scale on-site production. Lower investment cost better for remote locations and custom work. Output limited to 20-25 pieces per minute based on size. |
| Stationary Industrial | Integrated high capacity lines designed for continuous high volume output exceeding 50 pieces per minute. Require permanent facility and high initial expenditure offset by productivity over time. Ideal for large orders. |
Portable Machines offer mobility in production location and meet smaller batch requirements economically while ability to create specialty profiles on-demand. Well suited for remote construction sites.
Industrial Lines engineered for 24/7 high speed mass production in fixed factory infrastructure. Parametric control allows fast reproduction of standard profiles. The high output results in lower unit cost for large orders.
Choose machine type based on expected order demand, location constraints, power availability and budget.
Working Principle of Roll Forming Process
The common steps in the automated roll forming sequence are:
1. Decoiling – Feed stock coil loaded and sheet end aligned to entry
2. Feeding – Powered rollers pull sheet into start of line
3. Formation – Sheet formed gradually through consecutive stations
4. Cutting – Finished studs sliced to length by built-in cutter
5. Stacking – Formed pieces discharged onto table for bundling
Detailed Process Flow:
- Operator loads specified coil of sheet steel on powered de-coiler
- De-coiler feeds metal sheet into initial forming stands
- Sheet progresses through series of rolling header stations
- Stations with contoured rollers incrementally bend sheet
- Final station forms finished stud profile and desired dimensions
- End cutting machinery slices pieces to length for discharge
- Conveyor sections transport cut product for stacking
- Bundled finished goods prepared for shipment
The adjustable tooling makes changing dimensions fast for various profiles. Next we examine materials, customization and more features.
