This double layer roll forming machine allows manufacturers to produce two different roofing sheet profiles using a single machine structure. The upper and lower forming layers operate independently, offering flexible production switching while saving workshop space and investment cost.
Constructed with a heavy-duty welded steel frame and precision CNC-machined rollers, the machine ensures accurate profile dimensions, smooth surface finish, and long-term stable performance. It is widely used in steel structure buildings, industrial factories, warehouses, commercial complexes, and residential roofing applications.
