The CZ Fully Automatic Purlin Machine is the mainstream equipment for producing steel structure purlins.

Its core features include one-key interchangeability between C and Z types, full-process automation, high precision, high flexibility, and low waste. Compared to traditional separate machines (C machine and Z machine), the overall advantages are significant.  

Core Functional Advantages: Dual-type in one machine, quick changeover, full flexibility  

CZ one-key interchangeability, no need to change rollers  

Built-in modular rotating roller sets / servo type change mechanism, set parameters via touchscreen, automatically switch between C/Z cross-sections without replacing molds or shims; fully automatic changeover takes only 3–8 minutes (manual type takes about 15–20 minutes), much faster than traditional separate machines which require 2–4 hours for mold change.
