This double layer roll forming machine is specially designed to manufacture two popular roofing sheet profiles (686 and 760) on a single integrated production line. The machine adopts advanced hydraulic cutting technology, PLC automatic control system, and precision chrome-plated rollers to ensure accurate forming, smooth cutting edges, and reliable long-term performance.
The double deck structure allows flexible production switching between two different profiles without replacing the entire machine, saving factory space and reducing equipment investment costs.
