This double layer roll forming machine is specially engineered to manufacture two different metal roofing sheet profiles within one compact and heavy-duty structure. The upper and lower forming layers can be switched according to production requirements, significantly improving productivity while reducing equipment investment and floor space.
The machine adopts advanced cold roll forming technology, high-precision chrome-plated rollers, and a robust welded steel frame to ensure accurate profile dimensions, smooth surface finish, and long-term reliable performance. It is widely used in industrial buildings, steel structure workshops, warehouses, commercial facilities, and residential roofing construction.
