Sigma Purlins Machine

 Sigma Purlins Machine is designed to make the sigma purline in batch fully automatically. Meanwhile it can be used to make C purline, U purline also. The sigma purlin system has been developed in conjunction with for many years. The system is designed primarily for use, on roofs, as secondary sheeting support.

Sigma sections are manufactured by cold roll forming pre-hot dipped galvanised steel, grade S450, having a minimum yield stress of 450N/mm2. Here we developed one rolling forming machine for making such profile with multiple punching.

The above range can not be made by one range, as thickness range too big, Normally thickness 1.5 to 4.0mm, or 3.5mm that will be better. Here are some usage for your reference:
