The Auto Size Changeable C Z Purlin Roll Forming Machine is an advanced cold roll-forming system developed by ZTRFM for producing high-quality C- and Z-shaped steel purlins. This machine is widely used in steel structure construction, roofing systems, industrial buildings, and renovation projects.
This automatic purlin roll forming machine can manufacture C and Z purlins with adjustable widths ranging from 100mm to 300mm. Normally, the machine processes steel materials with thicknesses of 1.5-3mm. In comparison, ZTRFM can also customize the machine structure to handle thicker materials from 4.0mm to 6.0mm according to customers’ production requirements.
Unlike traditional purlin machines that require manual roller replacement for different sizes, ZTRFM designs this machine with an automatic size adjustment system controlled by PLC. Therefore, operators can quickly change purlin dimensions through the control panel, improving production efficiency and reducing unnecessary downtime.
ZTRFM provides complete solutions for global customers. Our professional international trade team offers technical communication and after-sales support to help customers successfully operate the equipment worldwide. At the same time, more than 20 experienced engineers continuously optimize machine structures and components to meet different production requirements. Every manufacturing process follows strict ISO quality management standards to ensure reliable machine performance.
Automatic Size Change System and Flexible C/Z Profile Production
The biggest feature of this Automatic C Z Purlin Roll Forming Machine is its intelligent size-changing function. ZTRFM integrates automatic adjustment motors and PLC control technology, allowing the machine to produce different purlin specifications without manually changing rollers.
Furthermore, the machine supports both C purlin and Z purlin production. When switching between C and Z profiles, the adjustment process only requires approximately 10 minutes, which significantly improves production flexibility and saves valuable working time.
The machine can manufacture various structural purlins, including:
- C purlin
- Z purlin
- U purlin
- Customized steel profiles
The adjustable production range includes:
- Width: 100-300mm
- Height: 50-100mm
- Thickness: 1.5-3mm
According to customers’ profile drawings, production capacity, tolerance requirements, and investment budget, ZTRFM engineers provide customized machine solutions. For customers who only require several fixed sizes, ZTRFM can also provide manual size adjustment systems, which offer a more economical choice.
Complete Punching, Forming and Cutting Production Line
The complete C/Z Purlin Roll Forming Machine Production Line integrates multiple working units to achieve continuous automatic production. The production line usually includes a decoiler, leveling system, punching system, roll forming system, and cutting system.
Before forming, the decoiler automatically feeds the steel coil into the production line. The leveling device straightens the raw material and improves forming accuracy. After that, the punching unit creates holes or slots according to customer drawings.
For punching requirements, ZTRFM provides flexible solutions:
- Pre-punching system
- Post-punching system
- Hydraulic punching station
Customers can select the suitable punching method according to their production process.
In addition, the cutting system can also be customized according to different applications:
- Pre-cutting system
- Post-cut universal cutting system
The universal cutting method allows the machine to produce different lengths efficiently without frequently replacing cutting tools.
For the driving system, ZTRFM selects suitable transmission solutions according to material thickness. When processing materials thicker than 2.5mm, the machine can adopt a stronger gearbox and gimbal transmission system, which provides higher driving force and more stable forming performance compared with ordinary transmission structures.
High Precision Structure and Technical Parameters
ZTRFM focuses on mechanical stability and long-term operation reliability. The machine adopts high-quality forming rollers, precise processing technology, and durable components to ensure that every produced purlin meets required dimensional accuracy.
The forming rollers are manufactured from high-strength materials such as GCr15, while customers can also choose Cr12MoV rollers for higher wear resistance.

C Purlin and Z Purlin Roll Forming Machine Applications
A C Purlin Roll Forming Machine is an industrial production system used to manufacture C-shaped steel purlins. The machine gradually forms flat metal coils into C profiles through a series of precision rollers.
During production, the machine normally includes a decoiler, leveling unit, punching system, forming stations, and cutting device. These components work together automatically to feed, straighten, shape, punch, and cut steel materials into finished C purlins.
C purlins are widely used as structural support components in:
- Steel building roofs
- Wall systems
- Industrial workshops
- Warehouses
- Construction projects
A Z Purlin Roll Forming Machine is designed to produce Z-shaped steel purlins. Similar to C purlin machines, it uses roller forming technology to transform flat steel coils into accurate Z profiles.
Z purlins are commonly applied in:
- Large-span steel structures
- Roofing support systems
- Commercial buildings
- Metal framework projects
Because Z-shaped profiles provide excellent overlapping performance, they are especially suitable for large construction structures requiring strong load-bearing capacity.
Other Models Available
Beyond the C/Z/U/W Purlin Roll Forming Machine, ZTRFM also provides a complete range of specialized cold roll forming solutions for different open-section steel profiles. Each machine is designed according to specific structural requirements, material thickness, and production applications.
