With the rapid development of prefabricated construction and light steel partition systems, the demand for high-precision, efficient, and multi-specification light steel keel machines continues to grow. As a professional cold-formed roll forming equipment manufacturer, Sussman Machinery has launched the new C100 & C150 light steel C-channel keel roll forming machine, providing smart, high-stability production solutions for both commercial and industrial building applications.
This machine supports production of 0.8–1.6mm thick G550 high-strength galvanized steel, using advanced cold-rolling forming technology to ensure dimensional stability, high structural strength, and smooth surface finish. It is capable of producing both C100 and C150 specifications, meeting the diverse needs of modern construction projects.
I. Key Machine Advantages
1. Servo Motor Width Adjustment System
One of the machine’s main highlights is the servo motor-driven width adjustment, allowing quick switching between C100 and C150 sizes without complex manual adjustments.
Advantages over traditional manual adjustment systems include:
- Higher adjustment accuracy
- Faster size changeover
- Reduced downtime
- Lower labor error
- Increased automation level
- Ideal for batch production and multi-specification orders
This system significantly improves production efficiency for modern light steel construction projects with frequent specification changes.
2. High-Strength Material Compatibility
The machine is designed to handle:
- Steel thickness: 0.8–1.6mm
- Material: G550 high-strength galvanized steel
Finished keels have excellent load-bearing capacity, deformation resistance, and corrosion resistance, fully meeting modern building requirements for structural stability.
3. Intelligent Control System
The machine integrates a PLC control system with a hydraulic high-speed cutting unit for automated continuous production.
- Stable operation
- Clean, burr-free cuts
- Improved finished product quality and production efficiency
High-quality PVC safety covers protect critical components and improve overall industrial aesthetics, meeting international equipment standards.
Now we will introduce the finished products make by machines.

III. C100 vs. C150: Key Differences
C100 — Standard Commercial Office Partitions
C100 is designed as a cost-effective, medium-load light steel keel widely used in commercial spaces.
Applicable scenarios:
- Walls ≤5m high
- Office partitions, conference rooms, corridors
- Hotel and apartment unit walls
- Machine rooms, retail spaces
Construction features:
C100 vertical keels are typically combined with U-shaped top and bottom tracks, spaced at 600mm. The structure is uniform and easy to install with gypsum boards, allowing fast construction.
Advantages:
- Material-efficient, low cost
- Lightweight, reduces overall building load
- Quick installation, shortens construction time
- Compatible with gypsum boards for good sound insulation and fire resistance
C100 is the mainstream choice for modern office and commercial partition walls.
C150 — Industrial and High Partition Heavy-Duty Solution
C150 has a larger cross-section and higher structural rigidity, suitable for large spaces and high walls.
Applicable scenarios:
- Walls 5–8m high
- Industrial plants, warehouses
- Large retail spaces
- High-rise lobbies, elevator shafts, utility shafts
- Fire partition walls
Construction features:
C150 keels paired with fireproof rock wool meet industrial fire and acoustic standards. Large cross-sections provide excellent bending resistance, maintaining stability in high walls and large-span spaces over long-term use.
Advantages:
- High structural rigidity for tall walls
- Supports high loads and large spans
- Compatible with fire-rated systems
- Excellent deformation resistance
- Light steel properties: moisture-resistant, corrosion-resistant, easy maintenance
C150 is ideal for industrial buildings and large-scale public spaces.
IV. Quick Selection Guide
Choose C100 for:
- Offices, retail, hotels, apartments
- Standard indoor partitions ≤5m
- Projects prioritizing cost efficiency and fast installation
Choose C150 for:
- Industrial plants, warehouses, large venues
- Walls >5m high, elevator shafts, fire partitions
- Heavy-load partitions requiring high rigidity and fire compliance
Also you can choose both of them to make, Sussman Machinery can make multiple sizes in one machine.
