This automatic purlin machine is a complete cold roll forming production line designed to manufacture the full spectrum of structural steel purlins — C purlins, Z purlins, CZ-integrated switching, and CZU all-in-one profiles — from a single heavy-duty platform. The machine serves as the backbone equipment for steel structure factories supplying pre-engineered building systems, industrial workshops, warehouse frames, and solar farm mounting structures. With a rigid archway frame machined to 0.05mm flatness and fully automatic servo-driven adjustment across all four profile dimensions, operators can switch between multiple purlin types and sizes in under one minute without mechanical tool changes.
