This double layer roll forming machine is specially developed to manufacture two metal roofing sheet profiles within a single compact machine structure. The upper and lower forming layers allow flexible production switching, significantly improving efficiency while reducing equipment investment and floor space usage.
The machine adopts advanced cold roll forming technology, a heavy-duty welded steel frame, and CNC precision machined rollers to ensure accurate profile shaping and smooth panel surface. It is widely used in industrial buildings, warehouses, workshops, residential houses, and agricultural structures.
