At Zhongtuo Intelligent Equipment, we’re not just delivering machinery—we’re providing fully integrated roll forming solutions that help manufacturers scale with speed, precision, and flexibility. Today, we’re proud to highlight a successful case study: the installation and commissioning of our CZ Purline Machine at a client’s steel fabrication facility in Bulgaria.
This state-of-the-art equipment is designed for construction professionals, steel structure fabricators, and industrial metal processing enterprises that demand high performance and seamless adaptability.
On-Site Success: Bulgarian Factory Installation
Recently, our engineering team completed the on-site setup of the CZ purline roll forming machine at a customer’s production base in Bulgaria. From unloading to testing, the entire installation process was completed swiftly, thanks to our modular design and plug-and-play systems. After commissioning, the machine began producing perfectly formed C and Z profiles, ready for use in structural steel projects.
This case not only showcases our machinery’s performance but also demonstrates how Zhongtuo provides hands-on technical support, ensuring every client can fully leverage their investment from day one.
Why Zhongtuo’s CZ Purline Machine Stands Out
Seamless C-to-Z Profile Conversion
One of the standout features of our CZ Purline Machine is its automatic size and profile conversion system. Operators can switch between C and Z profiles—along with different web and flange dimensions—through simple adjustments via the touchscreen interface. No need to manually replace rollers or perform mechanical recalibration.
This rapid changeover capability significantly improves productivity, especially for businesses dealing with varied purlin dimensions in quick succession.
✅ Integrated CAD-to-Punching Automation
To further reduce production time and errors, Zhongtuo’s CZ roll forming line includes automated CAD profile conversion for punching. Instead of manually entering punching patterns, CAD drawings are automatically translated and imported into the control system. This innovative approach:
Eliminates time-consuming data input
Prevents human error
Enhances punching precision
Speeds up production cycles
With a punching unit capable of delivering accurate hole placement at high speed, this system helps ensure structural compliance in steel buildings and infrastructure projects.
Certified Quality You Can Trust
We understand that investing in heavy-duty equipment requires assurance of reliability and compliance. That’s why our CZ Purline Machines are certified by CE, SGS, CAS, and UL, meeting international standards for quality, safety, and performance.
These certifications reflect our commitment to delivering durable and dependable roll forming solutions that can withstand the rigors of continuous operation in demanding environments.
Full Equipment Suite for One-Stop Steel Production
Zhongtuo’s CZ purlin line comes as a comprehensive production unit, offering everything you need to begin immediate manufacturing:
Manual uncoiler for efficient material feeding
Pre-leveling system for flatness correction before forming
High-speed punching station with servo-driven accuracy
Hydraulic shearing unit for clean, burr-free cuts
Forming system with stepless hydraulic adjustment
Automatic stacking and flipping system for finished profiles
This all-in-one setup reduces the need for separate machines, saving space and simplifying workflow in your factory.
Smart Remote Monitoring and Maintenance
Uptime is crucial in high-throughput manufacturing environments. That’s why our CZ Purline Machines come equipped with a remote operation and diagnostics system. Through secure software, our technicians can:
Monitor system performance in real time
Adjust programming settings remotely
Troubleshoot mechanical or electrical issues without needing on-site presence
This remote support technology minimizes downtime, especially for overseas clients, and ensures a quick response in the event of operational challenges.
Speed, Precision, and Reliability – All in One
Our CZ purline roll forming machine achieves production speeds of up to 20–25 meters per minute, depending on material thickness and profile complexity. Even at high speed, the system maintains dimensional tolerances within ±0.5mm, ensuring consistent, high-quality output for every batch.
Whether you’re producing standard C or Z sections for steel frames, or customized purlin designs for pre-engineered buildings, this machine delivers repeatable performance and minimal maintenance.
Ideal for Steel Fabricators Worldwide
If you’re in the construction or metal fabrication business, especially dealing with industrial buildings, warehouses, greenhouses, or steel workshops, Zhongtuo’s CZ Purline Machine offers the flexibility and output you need. It is widely used by:
Construction contractors
Prefabricated building manufacturers
Metal building component suppliers
Steel structure fabricators
Our equipment is in operation across Europe, Asia, South America, and the Middle East—testament to its versatility and global trust.
