Interchangeable c/z purlin roll forming machine manufactures both Cee & Zed shaped section channels with shapes and sizes quick changed by PLC control.

For a steel structural building project, people always use Cee and Zed steel purlins (different web sizes and different flange sizes).

Firstly, A traditional c/z purlin roll forming machine can make many section channels of different sizes (standard: 6 different sizes varied from 80-300mm web sizes,50-100mm flange sizes,15-20mm leg sizes), but it needs manual changing and each size changing will take at least 2 hours, as a result, traditional c/z steel purlin roll forming machines don’t work so much efficiently.

Then, roll forming machine innovators have developed semi-automatic roll forming machines for producing C OR Z shaped channels (not C and Z).

Generally, on a semi-automatic c or z shaped channel roll forming machine, there are three separate rolling tools installed on three sub-frame which can move horizontally. Like a traditional c or z steel purlin roll forming machine, this semi-automatic roll forming machine makes different c or z shaped section channels by manual changing. However, on a traditional c/z purlin roll forming machine, we change spacers between rolling tools, while on a sem-automatic machine, operators just move the respective sub-frames to adjust for different sizes of web heights or flanges.

Brief Introduction of Interchangeable c/z purlin roll forming machine:

Due to the birth of semi-automatic c/z purlin roll forming machines, the changing time is greatly improved. However, this machine cannot make both C and Z shaped section channels. People still need two machines for the manufacturing of C and Z steel purlins. Investment on two roll forming machines (one Cee shaped section channel roll forming machine and one Zed shaped section channel roll forming machine) is not ideal solution to contractors or distributiors. As a result,  our genuis roll forming engineers have pictured out  a new type roll forming machine image in their mind.

Finally, a c/z purlin interchangeable roll forming machine has been designed to produce both C and Z steel purlins with any sizes available. The profile change including cutting dies for C to Z takes at most 30 minutes (just clutches taken out, a 180° turning on some rolling tools and clutches inserted in) and size change needs at most 5 minutes (just input the required distance through the touch screen on PLC control cabinet ). So much efficiency has been improved by this quick-change c/z steel purlin roll forming machine
