High-Efficiency quick change CZ purlin roll forming machine/steel frame purlin machine

This Heavy-Duty Quick-Change C/Z Purlin Roll Forming Machine represents an advanced, fully automated industrial production system engineered for rapid transformation between C-section and Z-section steel purlins.

Featuring an innovative 180° rotational roll-station cassette assembly and PLC-driven stepless motor size adjustment, this machine eliminates tedious manual roller re-stacking and spacer repositioning. Complete profile and dimension changes can be accomplished in minutes rather than hours, making it an ideal solution for structural steel frame profiles production.

• • Rapid C/Z Profile & Size Changeover: Integrated stepless adjustment system controlled via PLC. Convert between C and Z profiles or alter dimensions (width, height, lip) quickly without changing rollers manually.

  • Heavy-Duty Welded Frame Structure: Constructed with a high-rigidity, stress-relieved steel base frame to eliminate machine vibration, ensure smooth high-speed performance, and extend equipment service life.

  • Intelligent PLC Touchscreen Interface: Mounted on a flexible swivel arm for ergonomic operation. Supports multi-language settings, batch management, automatic length measurement, and real-time diagnostic tracking.

  • Precision Hydraulic Punching & Cutting: Equipped with heavy-duty hydraulic post-cutting and punching stations for clean, burr-free cuts and exact hole positioning.

  • High-Grade Roller Technology: Rollers are precision-machined from premium alloy steel (Cr12 / GCr15), vacuum heat-treated, and hard-chrome plated for superior wear resistance and surface finish on formed profiles.
