Metal purline and rails profile rolling forming machine is designed to do the production of various types purline profiles in batch fully automatic by rolling forming machine.

Metal purlins and rails suitable for use in industrial, commercial and agricultural applications. Metal purline and rails, something like C purline, sigma purline Z purline and others. Cold rolled purlins are increasingly being used to support tiled roofs. This application is particularly suitable for Zeds which have principal axes inclined from the web axes and which consequently have upslope restraint forces acting in opposition to the downslope load component thus minimising the large downslope forces inherent to this form of roofing. In this part, we will show you how to make metal purline and rails of different types in one machine.

Metal purline and rails profile rolling forming machine:

In the following part, let us check how the machine can make different types:

For the C and Z purline are quite normal, now let us check how to add sigma purline in this C and Z purline machine. Compared with C purline, sigma just has one bottom ribs up and also need the width and height adjustable.

The sigma ribs is made by those 8 rollers stations. The width and height can be adjusted by PLC according the customer requirements. As for the C and Z adjustment, by the following rollers design.

By this kind of technology, you can make many sizes and many shapes rails and purlines by one machine.
