Machine Introduction:

The multi-profile purlin roll forming machine, also called multi lanes purlin roll former, is used to produce different C Z U purlins in one machine. Different with normal purlin roll forming machine which can produce only one product, this roll former is much more effective and saves the factory space.

The 4 lanes purlin roll forming machine including:

1) Hydraulic uncoiler for 4 lanes steel coils

2) 4 lanes guiding rail

3) 4 lanes feeding table

4) Main roll forming machine for 4 different C Z U purlins

5) Hydraulic cutter separately for 4 different products

6) Roll former electrical cabinet

7) Run-out table
