This double layer roll forming machine is designed to manufacture two different roofing sheet profiles within one compact and heavy-duty machine frame. The upper and lower forming layers can be switched according to production requirements, improving flexibility while saving workshop space and investment cost.
The machine adopts cold roll forming technology, high-strength welded steel structure, and CNC precision machined rollers to ensure accurate profile forming and smooth finished panel surface. It is suitable for industrial buildings, warehouses, workshops, commercial facilities, residential houses, and agricultural constructions.
