This trapezoidal roll forming machine is designed for manufacturing trapezoidal metal roofing panels widely used in steel structure construction. The production line integrates coil feeding, guiding, cold roll forming, hydraulic cutting, and PLC control system to ensure stable operation and high production efficiency.
The machine uses precision machined rollers and a strong welded frame to maintain consistent forming accuracy. With an advanced PLC touch screen interface, operators can easily set product length, monitor machine status, and control the production process automatically.
It is suitable for processing PPGI, galvanized steel coil, and color coated metal sheets to produce durable trapezoidal roof panels with uniform dimensions and excellent appearance.
