This double layer roll forming machine is designed for efficient production of two different roofing sheet profiles within a single compact structure. The upper and lower forming systems can operate independently, allowing manufacturers to switch profiles quickly and improve productivity.
Constructed with a reinforced welded steel frame and precision machined rollers, the machine ensures accurate forming, smooth panel surface, and long-term stable operation. It is widely used in industrial construction, steel structure workshops, warehouses, commercial buildings, and residential roofing projects.
