This double layer roll forming machine is designed to produce two different roofing sheet profiles using a single integrated production line. The upper and lower layers can operate independently, offering high production flexibility while saving valuable workshop space.
The equipment adopts advanced cold roll forming technology, heavy-duty welded frame construction, and high-precision CNC processed rollers to ensure smooth panel surface and accurate profile forming. It is widely used in steel structure buildings, industrial roofing projects, and construction material manufacturing plants.
