This double layer roll forming machine is specially engineered to manufacture two different roofing sheet profiles, such as glazed tile sheet and corrugated or trapezoidal sheet, within one compact and robust machine structure. The dual-layer configuration allows quick switching between profiles, maximizing productivity while reducing equipment cost and factory space.
The machine adopts advanced cold roll forming technology and high-precision CNC processed rollers to ensure smooth surface finish, accurate dimensions and stable forming performance. It is widely used in steel structure buildings, industrial plants, warehouses, commercial facilities, residential houses and agricultural construction projects.
