You can manufacture four type of C purlin by one machine through change the blades
Capability feature：
1）Base of machine is processed by gantry process centre and the locating pin of screw connects wall of machine stand. Panel can be formed with straightness, which guarantees the high accuracy.
2）Adopts hydraulic interlaced cutting which makes sure of the exact geometrical profile of formed panel. This cutting method causes no waste material.
3）Adopts computer for measuring of length. Two sides of C purlin have been punched with elliptical holes and the distance between holes can be adjustable. The bracing holes are punched in the middle of purlin.
Equipment includes:
Manual un-coiler:
1) Un-coiler: umbrella type
