Recently, a customer from Algeria visited Zhongtuo factory to inspect and test a newly manufactured Automatic C/Z Purlin Roll Forming Machine. During the factory visit, the customer conducted a detailed inspection of the machine structure, production process, control system, and finished product quality.
During the acceptance test, the customer personally witnessed the complete running process of the production line. The machine operated smoothly, the forming process was stable, and the finished C and Z purlins showed excellent dimensional accuracy and surface quality.

After the successful testing, the Algerian customer highly recognized the performance of the equipment and expressed satisfaction with Zhongtuo’s manufacturing quality and professional service.
Advanced C/Z Purlin Production Solution for Steel Structure Projects
The inspected equipment is a fully automatic C/Z Purlin Roll Forming Machine designed for producing high-strength steel purlins used in modern construction projects.
C purlins and Z purlins are important structural components in steel buildings. They are widely used as roof supports, wall framing members, and structural reinforcement elements in industrial factories, warehouses, commercial buildings, agricultural facilities, and prefabricated steel structures.
Compared with traditional building materials, cold formed steel purlins offer advantages such as lightweight structure, high strength, corrosion resistance, easy installation, and long service life.

To meet different project requirements, Zhongtuo’s Automatic C/Z Purlin Machine can produce multiple specifications with intelligent automatic adjustment. The machine can quickly switch between C profile and Z profile through the PLC control system, greatly reducing production preparation time.
The equipment supports:
- C purlin size: 80–350 mm
- Z purlin size: 120–350 mm
- Material thickness: 1.0–3.5 mm
- Material grade: Q235 / Q345 / Q420
- Automatic size adjustment
- Automatic C/Z profile conversion
Customer Witnesses Perfect Machine Performance During Factory Acceptance Test
During the factory acceptance test, the Algerian customer carefully checked every production section of the machine, including:
- Automatic feeding system
- Leveling unit
- Hydraulic punching system
- Pre-shearing system
- Roll forming section
- Electrical control system
- Finished product receiving table
After feeding the steel coil into the machine, the entire production line completed the process automatically:
Uncoiling → Feeding → Leveling → Hydraulic Punching → Pre-Shearing → Roll Forming → Finished Product Receiving

The customer observed that the machine maintained stable operation throughout the production process. The finished purlins were accurately formed with consistent dimensions, smooth surfaces, and excellent structural quality.
The customer especially appreciated the machine’s automatic adjustment function, which allows operators to quickly change different purlin sizes without complicated manual operations.
After the acceptance test, the Algerian customer gave positive feedback on the performance of the Automatic C/Z Purlin Roll Forming Machine.
The customer commented:
“The machine runs very smoothly, the forming accuracy is excellent, and the automatic C/Z profile change function is very convenient. We are very satisfied with the machine performance and Zhongtuo’s professional service.”

The customer’s recognition reflects the reliability of Zhongtuo’s manufacturing technology and the company’s commitment to providing high-quality roll forming solutions for customers worldwide.
Intelligent Automation Improves C/Z Purlin Production Efficiency
