Fully Automatic CZ Purlin Steel Profiled Interchangeable Roll
Forming Machine
Product description:
CZ changeable purlin roll former can produce both c and z purlin
with different specifications in one machine. The change from C and
Z will be done by manual adjustment. There is also not necessary to
change the rollers if producing different size of C or Z purlins.
It can automatically cut to length, punch and forming, workers just
need to set the length, hole distance, quantity, etc into the
control system. The finished products are widely used as the
supporter of roof and wall in large-scale and mid-scale
construction, such as factory, warehouse, garage, exhibition
center, cinema, theatre, garden and so on.
