In the global steel structure industry, C-shaped and Z-shaped steel purlins are essential core components, widely used as roof purlins, wall girts, floor beams and supporting frameworks in industrial workshops, warehouses, commercial buildings, steel structure houses and large-span venues. With their lightweight, high load-bearing capacity, easy installation and cost-saving advantages, CZ purlins have become the preferred choice for modern steel structure construction. To meet the large-scale, standardized production needs of CZ purlins, a professional dual-function CZ purlin roll forming machine is the key to enhancing production efficiency and product quality for steel structure material manufacturers.

We are a professional foreign trade supplier specializing in R&D, manufacturing and global export of metal cold roll forming machinery, with rich experience in steel structure equipment R&D and production. Our CZ purlin roll forming machine is specially designed for the integrated production of C-shaped and Z-shaped steel purlins, breaking through the limitations of single-type forming equipment and solving the pain points of traditional processing such as low efficiency, unstable size, high labor costs and difficult mold replacement. Fully compliant with steel structure construction standards in Europe, North America, Southeast Asia, the Middle East, Africa and South America, this machine helps global customers achieve dual-function mass production, reduce investment costs and gain a competitive edge in the steel structure market.

Core Advantages & Unique Features

Dual-Function Integrated Forming, One Machine for Two Purlins

The biggest highlight of this machine is its dual-function design, which can freely switch between C-type and Z-type purlin forming without disassembling the entire roll set. Equipped with a quick mold switching system, the conversion between C-shaped and Z-shaped profiles can be completed in 10-15 minutes, greatly reducing downtime and improving production efficiency.

Adopting a scientifically designed multi-pass progressive rolling forming process, the machine accurately forms the standard C/Z-shaped profiles, ensuring uniform web, flange and lip dimensions, straight edges and stable structure without deformation. The forming roll set is custom-machined according to international standard CZ purlin specifications, perfectly restoring the profile shape and ensuring that the finished purlins have excellent load-bearing performance and installation fit, fully meeting the requirements of various steel structure projects.

High-Precision Forming, Strict Size Consistency

Precision is the core requirement for CZ purlins, as it directly affects the installation accuracy and structural stability of steel structures. Our machine is equipped with a high-precision PLC servo positioning system and laser alignment device, strictly controlling the dimensional tolerance of finished purlins.

The forming rolls are forged from high-grade Cr12MoV alloy steel, treated with overall quenching, tempering and precision grinding, with a surface hardness of HRC 60-63, featuring excellent wear resistance and compression resistance. The web height, flange width and lip size errors are controlled within ±0.1mm, and the length error is less than ±0.2mm. The finished purlins have smooth surfaces, no burrs, no scratches and no material damage, eliminating the need for secondary trimming and ensuring fast and accurate on-site installation.

Fully Automatic Continuous Production, Maximize Efficiency & Save Labor

This machine realizes a full-process automatic production line, covering automatic uncoiling, hydraulic leveling, precision feeding, roll forming, fixed-length flying cutting, hole punching (optional) and automatic stacking, with seamless linkage of all processes and no manual handling required. It completely abandons the traditional manual cutting and semi-automatic forming mode, greatly shortening the production cycle.

Equipped with a high-power heavy-duty servo motor and stable transmission system, the forming speed can be flexibly adjusted between 10-28 meters per minute, supporting 24-hour uninterrupted operation. A single machine can produce 5000-10000 meters of qualified CZ purlins per day, easily coping with large-scale project orders. The user-friendly touch screen control panel with full English interface supports one-key parameter setting, automatic counting and fault alarm, only requiring 1-2 workers for routine monitoring, reducing labor input by more than 75%.

Robust & Durable Structure, Long Service Life & Low Maintenance

To adapt to long-term high-load heavy-duty production, the whole machine adopts an extra-thick H-shaped steel frame, with integrated welding and stress relief annealing treatment, featuring ultra-high rigidity and low vibration. It remains stable and deformation-free during continuous high-intensity operation, ensuring consistent forming accuracy and prolonging the service life of core components.

All key electrical components, bearings, hydraulic valves and cutting blades are selected from internationally renowned brands such as Siemens, Omron and Schneider, with an extremely low failure rate. The modular design makes daily maintenance and vulnerable parts replacement simple and fast, without professional maintenance personnel. Compared with traditional single-function forming machines, it reduces maintenance time and cost by 40%, and the service life can reach more than 15 years under normal maintenance, bringing long-term stable returns for manufacturers.

Wide Compatibility & Flexible Customization

To adapt to the diverse needs of the global market, our CZ purlin roll forming machine offers strong compatibility and personalized customization options. It can process various metal coils with a thickness of 0.8mm-3.0mm, including hot-dip galvanized steel, cold-rolled steel, weather-resistant steel and aluminum alloy, meeting different anti-corrosion and strength requirements.

We support customized production of CZ purlins with different specifications, covering conventional web heights (100mm-300mm) and flange widths (50mm-150mm), as well as non-standard sizes according to customer requirements. The machine is equipped with adjustable forming parameters, enabling flexible adjustment of profile dimensions without replacing the entire roll set, improving production flexibility and adapting to both small-batch customized orders and large-scale mass production.

Energy-Saving & Safe Operation, Comply with Global Standards

The machine is equipped with a variable frequency energy-saving control system, which automatically adjusts power output according to production load, reducing power consumption by 20%-25% compared with ordinary fixed-speed forming machines, in line with global green production requirements. The full-covered safety guard and safety interlock device effectively prevent accidental injuries during operation, and the running noise is controlled below 75dB, complying with international occupational health and safety standards.

The continuous coil processing mode improves material utilization rate to more than 97%, minimizing leftover materials and reducing production waste. The closed dust-proof structure reduces metal dust emission, creating a safer and more eco-friendly production environment.
