This double layer roll forming machine is engineered to produce two different metal roofing sheet profiles within a single compact structure. The upper and lower forming layers operate independently, allowing flexible production while saving installation space and reducing equipment costs.
Built with a heavy-duty welded steel frame and high-precision CNC processed rollers, the machine ensures stable operation, accurate forming, and long service life. The advanced PLC control system allows automatic length setting, quantity control, and high-efficiency continuous production.

The double layer configuration significantly improves production flexibility by allowing two different profiles to be produced on one machine. Compared with separate single-layer machines, it saves nearly half of the floor space and reduces total investment.
All forming rollers are processed with CNC precision machining and hard chrome plating to ensure durability and high forming accuracy. The PLC control system simplifies operation and enhances production efficiency.
We provide complete installation support, commissioning guidance, and after-sales technical service. Customized profile designs and machine configurations are available to meet specific project requirements.
