Purlin rolling machine
With the development of roll forming technology, automatic quick change roll forming machines for the production of C and Z purlins began to appear.In fact, the purlin machine is rapidly replacing the Z shape roll forming machines. Indeed, the automatic interchangeable purlin roll forming machine can also be called PLC automatic purlin roll forming machine, one roll forming machine can produce steel purlin, flange size and edge size.
CZ rolling forming machine
CZ changeable Purlin Forming Machine is an equipment that produces C/Z shaped steel channels continuously out of galvanized or cold rolled steel strips from feeding, punching for holes, bending and cutting.
CZ rolling forming machine feature
This machine can do a rapid Inter-changeable CZ Purlin Roll forming System.
Capable of producing the standard industry range of Cee, Zee, U shapes 80-300mm within the thickness of 1.5 to 3.2mm.
Providing programmable modular hydraulic punching and cutting as default we give 5 types of punching dies.
Rapid C/Z profiles and its size changeover times under 5 minutes.
European quality control, machine surface adopts powder coating, coating before assembly.
Delivery capacity 220-300 sets per year, the largest and most professional manufacturer in China.
Fast delivery, once receive the deposit we can arrange the delivery within 25 days.
