Our CZ purlin roll forming machine is a professional, fully automatic cold forming equipment dedicated to producing high-quality C and Z steel purlins — the core load-bearing components for modern steel structure buildings. Designed as an all-in-one solution, it replaces two separate single-profile machines, enabling seamless production of both C and Z purlins in one unit, with a full automatic workflow from coil feeding, leveling, roll forming, punching, fixed-length cutting to finished product stacking. Widely used in industrial workshops, warehouses, prefabricated buildings and commercial construction projects, it delivers exceptional cost savings and efficiency for global metal processing and construction clients.

Key Advantages & Core Strengths

One-Click CZ Profile Switching, Maximum Cost Savings

This machine features automatic C/Z profile conversion as its core highlight, with no need to disassemble forming rollers or replace molds manually. Operators can switch between two profile types via the touch screen in only 5-10 minutes, cutting equipment investment cost by up to 50% and saving over 60% of workshop space compared with owning two separate machines. It covers all standard C (80-300mm) and Z (80-300mm) purlin sizes, perfectly matching diversified order demands and eliminating extra equipment costs for mixed production.

Fully Automatic Continuous Production, Ultra-High Efficiency

Equipped with a hydraulic uncoiler, precision leveling system and PLC intelligent control panel, the machine runs stably at 8-25m/min for 24-hour uninterrupted production. It supports automatic length setting, batch counting, flying cutting and automatic stacking, realizing unmanned production and reducing manual labor input by 70%. Overall production efficiency is over 60% higher than semi-automatic models, greatly shortening order delivery cycles and boosting output for large-scale batch manufacturing.

High-Precision Forming, Stable & Consistent Quality

Driven by high-precision servo motors and imported encoder positioning, the machine controls product size tolerance within ±0.5mm, ensuring every finished purlin has uniform dimensions and perfect fitting performance. Forming rollers are made of high-grade 45# carbon steel with precision grinding and hard chrome plating, offering excellent wear resistance and long service life. The final purlins feature smooth surfaces, no burrs or distortion, and qualified structural strength, fully complying with international steel structure building standards.

Heavy-Duty Durable Build, Low Failure Rate

The main frame adopts thickened high-strength welded steel with overall annealing treatment, featuring high rigidity and zero deformation even under long-term high-load operation. Key electrical components use international premium brands (Siemens, Schneider) for stable running, while the precision gearbox transmission ensures low noise and smooth operation. The sturdy structure reduces downtime and maintenance frequency, extending the machine’s service life and lowering long-term operating costs.

توافق واسع وتنوع قوي في الاستخدامات

Suitable for various metal coils including galvanized steel, cold-rolled steel and aluminum-zinc coated steel, with material thickness ranging from 1.5mm to 4.0mm, covering mainstream raw material specifications in the global market. It supports customized profile sizes and punching positions to adapt to different regional building standards and client-specific project needs, making it a versatile choice for small and medium-sized factories to large construction enterprises.

Easy Operation & Low Maintenance

With an intuitive English touch screen interface, parameter setting is simple and clear, and new operators can master operation quickly after short training. The system has built-in fault self-diagnosis and alarm functions for quick troubleshooting. Daily maintenance only requires regular lubrication and routine checks, with simple steps and minimal maintenance costs.
