C-Z quick interchangeable machine adopts a special structure. The rollers for C & Z are changed very quickly without dismantle any parts. One machine can produce all specifications of C & Z purlins. This machine adopts steel coils as material and gets profiled steel after the process of coiling, cutting, punching, and roll forming. Whole machine adopts PLC controlling, AC frequency speed regulating to fulfill the automatic production, which is very suitable for the metal cold rolled processing industry.
