CU Purlin roll forming machine is the most popular and has an wild use in Metal Building Systems, Huge Roofing Solutions, Construction and Renovation Projects etc. C/U Purlin roll forming machine can produce C/U/Z purlin, machineable size range as follow: Width:80-300mm, Height: 40-100mm, Thickness:1.5-3mm. Raw material could be: cold-rolled steel, Galvanized steel, PPGI, high-tensil steel. We also can make the heavy duty CU purline, the Max thickness is 4.0mm or more, the max thickness can meet the customer requirement.

According to your section profile, size range, thickness range we could provide you different solutions of purlin roll forming machine to manufacturer a complete range of structual purlins,C to U can be adjusted by manual or automatic.

Regarding the cutting unit ,you can choose the pre-cut, post cut or both. Gearbox driving system with cast iron stands are more durable and recommendable.

Main structure & characteristics:
1. There is no need to change the cutting blade;
2. With quick interchangeable; By this design, we adopted the newly method for changing the specifications. It only needs 10 minutes to interchange anyone specification; 
3. Adjustability: the specifications for C80-300/ Z100-300 can be adjusted easily and freely.
4. This production line can be used to produce different specifications of the Cprofiles by automatic & manual controlling. There is no need to change the forming rollers when changing the specifications. →
5. To change any of the C profiles, it only needs 5 minutes by a simple manual operation.
6. With easy & simple operation, and largely reducing the operating difficulties, saving production time and largely improving the productivity.
7. This C purlin production line consists of the guiding & leveling device, main forming machine (with quick interchanging device), 2 hydraulic ounching devices, hydraulic cutting device, hydraulic station, electric controlling system and run-out table, etc.
