CZ Purlin Machine – Automatic C & Z Purlin Changeover with PLC & Servo Control
The CZ Purlin Machine is an advanced cold roll forming solution designed for manufacturers who need flexible and efficient production of both C purlins and Z purlins. With an intelligent PLC control system combined with servo motor technology, the machine can automatically change from C purlin production to Z purlin production, or from Z purlin back to C purlin.
This automatic changeover design significantly reduces manual adjustment, minimizes downtime, and makes the machine an ideal choice for modern steel structure and construction material manufacturers.
One Machine for Both C and Z Purlins
Traditional C purlin and Z purlin production often requires separate machines or extensive manual adjustments when changing profiles.
Our CZ Purlin Machine provides a more flexible solution.
The machine can automatically switch between:
- C Purlin
- Z Purlin
- Different web widths
- Different flange dimensions
- Different punching configurations, depending on machine design
With the right production parameters entered into the PLC system, the machine automatically adjusts the forming position and related components through servo-driven mechanisms.

Automatic C to Z Changeover
When changing from a C purlin to a Z purlin, operators do not need to manually dismantle and reposition multiple forming components.
The PLC sends control instructions to the servo motors, which automatically adjust the relevant machine positions to achieve the required C or Z profile.
This allows manufacturers to switch production quickly and efficiently.
Automatic Z to C Changeover
The same principle applies when changing from Z purlin back to C purlin.
After selecting the required profile from the control panel, the PLC system coordinates the servo motors to automatically complete the necessary adjustments.
This makes the CZ purlin production line especially suitable for customers who frequently produce different structural steel profiles.
PLC + Servo Motor: Intelligent Automatic Adjustment
One of the key advantages of this CZ Purlin Machine is the combination of PLC control and servo motor technology.
The PLC acts as the control center of the machine, while servo motors provide precise positioning and adjustment.
The system can control automatic adjustments such as:
- C/Z profile changeover
- Forming station positioning
- Profile width adjustment
- Flange adjustment
- Punching position adjustment, depending on configuration
- Cutting position coordination
Instead of relying on time-consuming manual measurements and mechanical adjustments, operators can select the required production specification through the HMI touchscreen.
The machine then performs the corresponding adjustments automatically.
Faster Profile Changeover
For manufacturers producing multiple types of purlins, production flexibility is extremely important.
A conventional machine may require operators to stop production and manually adjust machine components before producing another profile.
The CZ Purlin Machine simplifies this process through automated changeover technology.
C → Z
Select Z purlin on the control panel → PLC processes the parameters → servo motors automatically adjust → machine starts Z purlin production.
Z → C
Select C purlin on the control panel → PLC processes the parameters → servo motors automatically adjust → machine starts C purlin production.
This helps reduce setup time and improves overall production efficiency.
Designed for Steel Structure Applications
C and Z purlins are widely used as secondary structural members in steel buildings.
Typical applications include:
- Steel warehouse buildings
- Industrial workshops
- Agricultural buildings
- Commercial buildings
- Steel structure factories
- Storage facilities
- Roofing systems
- Wall systems
- Solar mounting structures
- Construction projects
By using one flexible production line for both C and Z profiles, manufacturers can respond more efficiently to different project requirements.
User-Friendly PLC Control System
The machine is equipped with a user-friendly PLC control system and touchscreen HMI.
Operators can enter or select the required production parameters directly from the control panel.
The PLC system manages the production process, including:
- Length setting
- Quantity setting
- Automatic stopping
- C/Z profile selection
- Servo positioning
- Cutting control
- Production monitoring
- Error and alarm information
The intuitive interface makes machine operation easier, even when switching frequently between different purlin specifications.
Precision Servo Positioning
Servo motors provide accurate and repeatable positioning during automatic profile changeover.
Compared with purely manual mechanical adjustment, servo-controlled positioning can help improve:
- Adjustment accuracy
- Repeatability
- Changeover efficiency
- Production consistency
- Operator convenience
This is particularly valuable for customers who need to produce multiple C and Z purlin sizes on the same production line.
Complete CZ Purlin Production Solution
A typical CZ purlin production line can be configured with:
- Decoiler
- Leveling and feeding system
- Roll forming machine
- PLC + Servo automatic adjustment system
- Hydraulic or servo-controlled punching system
- Hydraulic cutting system
- Run-out table
- PLC control cabinet
- HMI touchscreen
The exact configuration can be customized according to the customer's required purlin sizes, material thickness, punching patterns, production speed, and factory requirements.
