Our CZ purlin roll forming machine is a fully automatic, high-performance cold roll forming unit specially designed for the integrated production of C-shaped and Z-shaped steel purlins, the core load-bearing components for steel structure buildings. Unlike single-function profile machines, this model realizes quick and free switching between C and Z profiles without manual mold replacement, streamlining the whole production process from coil feeding, leveling, roll forming, punching, fixed-length cutting to finished product stacking. It is widely used in steel structure workshops, warehouses, commercial buildings, residential construction, agricultural facilities and prefabricated housing projects, serving global metal processing enterprises and construction contractors as a cost-effective, high-efficiency solution for profile production.

Core Features & Advantages

CZ Profile Quick Switching, Dual-Function Integration

The biggest highlight of this machine is its automatic CZ profile conversion function, which eliminates the need to purchase separate C purlin and Z purlin machines. Operators can switch between two profile types directly through the touch screen control panel in just 5-10 minutes, with no need to disassemble forming rollers or adjust complicated parts. This dual-function design cuts equipment investment cost by up to 50%, saves valuable workshop space, and perfectly meets diversified order demands for both C and Z steel purlins, covering all common specification sizes of C/Z purlins in the global construction market.

Fully Automatic Production, Ultra-High Efficiency

Equipped with a full-automatic production line including a hydraulic uncoiler, leveling device, servo feeding system and PLC intelligent control system, the machine realizes unmanned continuous production with a stable working speed of 8-25m/min. It supports automatic length setting, batch quantity counting, fixed-length flying cutting and automatic stacking, greatly reducing manual operation and labor input. Compared with traditional semi-automatic models, it improves overall production efficiency by more than 60%, easily meeting large-scale batch production requirements and shortening order delivery cycles.

High-Precision Forming, Stable Product Quality

The machine adopts high-precision servo motor drive and imported encoder positioning, ensuring strict control of product size tolerance within ±0.5mm and consistent profile dimensions for every finished purlin. Forming rollers are forged from high-quality 45# carbon steel, processed by precision grinding and hard chrome plating, featuring high wear resistance, no deformation and long service life. The professional roller design ensures smooth surface of finished CZ purlins, no burrs, no distortion and perfect structural strength, meeting international building steel structure standards and fitting tightly with other building components.

Heavy-Duty Stable Structure, Long Service Life

The main frame is made of thickened high-strength welded steel plate with overall annealing treatment, featuring high rigidity, excellent shock resistance and zero deformation even under 24-hour continuous high-load operation. The transmission system uses a high-quality gearbox and chain drive, running smoothly with low noise and low failure rate. Key electrical components adopt internationally renowned brands such as Siemens and Schneider, guaranteeing stable and reliable operation for long-term use, and reducing downtime caused by equipment faults.

Wide Material & Specification Compatibility

This machine is highly adaptable to various metal coil materials, including galvanized steel, cold-rolled steel, aluminum-zinc coated steel and color-coated steel, with a material thickness range of 1.5mm-4.0mm. It can produce C purlins (C80-C300) and Z purlins (Z80-Z300) of conventional and customized sizes, and supports adjustable flange width and height via parameter setting. It fully adapts to different regional building design standards and customer-specific project needs, with strong versatility and wide application range.

User-Friendly Operation & Low Maintenance Cost

The intuitive touch screen human-machine interface is simple and easy to operate, with clear parameter setting options and English display, allowing new operators to master basic operation after short-term training. The system is equipped with fault self-diagnosis and automatic alarm functions, quickly locating fault points for easy maintenance. Daily maintenance only requires regular lubrication and routine inspection, with simple steps and low maintenance cost, effectively reducing long-term operating expenses for enterprises.
