This high speed C purlin roll former is a fully automatic cold roll forming production line designed for continuous manufacturing of C-shaped steel channels. Built on a rigid 40-50mm archway frame machined to 0.05mm flatness, the machine delivers consistent profile accuracy across extended production runs. The servo-driven flying shear eliminates material stopping during cutting, achieving near-continuous throughput for high volume steel structure, warehouse, and solar farm projects.
