This double layer roll forming machine is engineered for efficient production of two different corrugated or trapezoidal roofing sheet profiles within a single machine frame. The upper and lower forming layers operate independently, providing flexible manufacturing options while saving workshop space.
The machine adopts advanced cold roll forming technology, heavy-duty welded structure, and precision CNC machined rollers to guarantee accurate shaping and long-term durability. It is suitable for roofing sheet manufacturers, steel structure contractors, and building material factories.
