In modern steel structure engineering, efficiency, precision, and material strength are essential requirements. The fully automatic CZ purlin roll forming machine is developed to produce high-quality C-section and Z-section steel purlins from metal coils with continuous automated processing.
This production line combines multiple functions including coil feeding, leveling, punching, roll forming, and hydraulic cutting into a single integrated system. As a result, manufacturers can achieve stable mass production while reducing labor dependency and operational costs.
Key Advantages of the CZ Purlin Machine
1.One of the most valuable features of this machine is its automatic C/Z profile changeover system. Operators can switch between C purlins and Z purlins directly from the control system without replacing rollers or molds. Consequently, the conversion time can be reduced to only 3–8 minutes, which greatly improves production flexibility for factories handling multiple orders with different specifications. 2.The machine adopts a high-performance motor and hydraulic cutting system, enabling stable operation during long production cycles. In addition, the automated PLC control ensures accurate length control and batch production. Under normal operating conditions, the production speed can reach 8–15 meters per minute, allowing manufacturers to achieve high daily output while maintaining excellent dimensional accuracy. 3.Another major advantage is the machine’s ability to process a wide range of metal materials. It can efficiently form:- Galvanized steel sheets (GI)
- Pre-painted steel sheets (PPGI)
- Aluminum coils
- High-strength steel strips
