This double layer roll forming machine is specially designed to manufacture two different roofing sheet profiles in a single integrated production line. The upper and lower layers can produce corrugated or trapezoidal panels independently, significantly saving factory space and reducing investment cost.
The machine adopts cold roll forming technology, PLC automatic control, and hydraulic cutting system to ensure high precision, smooth cutting edges, and stable high-speed operation. It is widely used in industrial buildings, warehouses, workshops, residential roofing, and agricultural construction projects.
