PLC Controlled Trapezoidal Roofing Sheet Roll Forming Machine

This trapezoidal roll forming machine is specially designed for the automatic production of metal roofing sheets and trapezoidal wall panels. The line adopts advanced cold roll forming technology to transform steel coils into uniform trapezoidal profiles with high forming accuracy and smooth surface quality.

The machine integrates feeding, guiding, roll forming, length measuring, hydraulic cutting, and discharge into one continuous production system. With a PLC control cabinet and touch screen operation interface, the operator can set production length, quantity, and cutting parameters quickly and efficiently.

Built with a rigid machine frame, precision machined rollers, and reliable hydraulic components, this equipment is suitable for long-term industrial production. It is widely used by roofing sheet manufacturers, steel structure contractors, and building material factories.
