Purlin Roll Forming Machine-FAQ
What is a purlin roll forming machine?
A purlin roll forming machine forms galvanized steel coil into C, Z and U shaped purlins — the horizontal structural members that support roof and wall cladding in steel buildings. Zhongyuan lines integrate leveling, punching, pre-cutting and roll forming in one automated production flow.

What is the difference between C purlin and Z purlin?
Z purlins have angled flanges that allow them to be lapped over supports, making them stronger for long-span roofs, while C purlins have vertical flanges and are typically used for simple spans, wall girts and shorter roof members. A C/Z/U purlin machine can switch between these profiles on one production line.

What sizes of purlins can the machine produce?
Zhongyuan purlin machines cover the common commercial size range — for example the C100-350-100 model produces C purlins with web heights from 100 to 350 mm and 100 mm flanges. Material thickness runs from 1.5 to 4.0 mm, and the exact size range is configured to the customer's market requirements.

What components does the complete purlin roll forming line include?
The complete line includes: a 3-ton double-head decoiler, guiding and leveling unit (4 upper + 5 lower rolls), two punching units, pre-cutting unit, roll forming system with about 18 stands (motors 3 × 7.5 kW and 1 × 5.5 kW), hydraulic stop-and-cut unit with Cr12MoV tool-steel blades, an 11 kW hydraulic power unit, a PLC control system (Delta from Taiwan or Mitsubishi from Japan), and non-powered run-out tables totaling 6 meters.

Can the purlin machine be customized?
Yes. Zhongyuan (Hangzhou Zhongyuan Machinery Factory) has designed custom purlin roll forming equipment since 2003. Profile size range, punching patterns, thickness range and automation level are all engineered from the customer's drawings and production requirements.
