Cangzhou Zhongtuo Roll Forming Machinery Co., Ltd., a national-level high-tech enterprise established in 2014, specializes in manufacturing advanced z purlin roll forming machine systems. Our equipment handles material thickness from 1-3.5mm with Z purlin dimensions ranging 120-350mm, processing steel with yield strength of 235/345 MPa. Each machine features servo motor drive technology, separate cabinet PLC control with Panasonic components, and Schneider electric parts, ensuring precision and reliability for your structural steel production needs.

Our machines incorporate cutting-edge technology developed through collaboration with Yanshan University's National Cold Rolled Strip Equipment and Process Engineering Research Center.
The roll forming system utilizes AI-powered finite element analysis (FEA) for optimal roller design. This ensures consistent profile accuracy throughout production runs. Your operation benefits from reduced material waste and improved dimensional stability.
Servo motor drive systems provide precise speed control and positioning. The separate cabinet PLC design protects sensitive electronics from factory floor conditions while simplifying maintenance access.
High-quality GCr15 forming rollers undergo heat treatment and hard chrome plating, achieving HRC55-58 hardness. This extends roller life significantly compared to standard tooling.

Your production efficiency increases through integrated automation features. Pre-punching systems position holes accurately before forming, eliminating secondary operations.
Remote monitoring capabilities allow you to track production metrics in real-time. Cloud-based diagnostics enable our technical team to provide support regardless of your location.
The intelligent operating system enables seamless size changeovers. You can switch between different purlin profiles without manual roller adjustments, reducing downtime significantly.
Hydraulic cutting systems deliver clean, burr-free cuts. The automatic stacker organizes finished profiles efficiently, reducing handling time and labor requirements.
We understand that your project requirements vary. Our engineering team designs solutions tailored to your specific needs.
Profile dimensions can be customized based on your structural calculations. Material specifications adjust to match regional building codes and client preferences.
Punching patterns configure to your connection requirements. Whether you need standard holes or complex patterns, our pre-punching system adapts accordingly.
Optional equipment includes automatic decoilers, advanced stacking systems, and extended conveyor tables. These additions optimize workflow for high-volume operations.

Each z purlin roll forming machine will be tested strictly before shipping. ISO 9001 accredited quality management system to provide consistent production standards.
CE certification ensures conformity with European safety requirements. CAS certification confirms compliance with North American technical criteria.
The first thing to consider while choosing components is their dependability. Schneider electric components, Panasonic PLC systems and quality Chinese motors guarantee consistent performance over the long term.
We work along with Yanshan University to constantly enhance our technology. Graduate researchers are on site, working on the latest breakthroughs in cold forming technology.
As machines are running effectively in more than 150 countries, we understand different market needs. We have expertise exporting to Europe, North America, the Middle East, South East Asia and South America.
Technical documentation consists of extensive operating, maintenance and trouble-shooting instructions. Your operators are trained to get the most out of your equipment.
The spare parts stockpile keeps vital components in stock. With our logistics network we can quickly send you replacements so you don’t have to stop production.
Reduce your installation duration with remote commissioning services. Our experts are able to virtually diagnose and optimise machine settings before on-site commencement.
Q:What's the difference between C and Z purlins?
A:Z purlins feature offset legs, making them ideal for continuous spans and overlapping connections. C purlins have parallel legs suited for simpler applications. Our machine can produce both profiles with appropriate roller configuration.
Q:How long does size changeover take?
A:With our automatic adjustment system, profile size changes complete in 3-5 minutes. Manual systems require 15-30 minutes. The servo-controlled positioning eliminates trial-and-error adjustments.
Q:What maintenance does the product require?
A:Daily lubrication of moving parts and weekly inspection of hydraulic fluid levels maintain optimal performance. Roller surfaces should be cleaned regularly. Annual professional inspection ensures long-term reliability.
Q:Can the machine handle different steel grades?
A:Yes, our equipment processes steel with yield strengths from 235-345 MPa. Material thickness ranges from 1-3.5mm. Consult our technical team for specialty materials or extreme specifications.
Q:What's included in machine installation?
A:We provide foundation drawings, installation supervision, operator training, and commissioning support. Remote assistance continues after installation. Extended on-site support is available upon request.
Q:How does energy accumulator technology improve punching?
A:The energy accumulator stores hydraulic pressure, enabling continuous punching without stopping the forming line. This doubles punching speed and maintains consistent production flow.
