Automatic Trapezoidal Roofing Sheet Roll Forming Machine

This trapezoidal roll forming machine is engineered for producing trapezoidal metal roofing panels used in modern steel structure buildings. The machine integrates coil feeding, guiding, continuous cold roll forming, hydraulic cutting, and PLC automatic control to create a highly efficient roofing sheet production line.

The equipment adopts a heavy-duty welded steel frame and high‑precision forming rollers to ensure long‑term stability and accurate panel profiles. With PLC touch screen operation, users can easily adjust product length, monitor production status, and achieve automated operation.

The machine can process galvanized steel, PPGI, color coated steel, and similar metal materials to produce durable trapezoidal roofing panels with smooth surface finish and strong structural performance.
