This double layer roll forming machine features a dual-profile system that enables the production of two different roofing sheet designs using a single integrated machine structure. The upper and lower forming layers can be selected based on production requirements, maximizing flexibility while minimizing investment cost and workshop space.
With a reinforced welded steel base and precision CNC-machined rollers, the machine ensures accurate forming dimensions, smooth finished surface, and consistent panel quality. It is widely applied in industrial buildings, steel structure workshops, warehouses, logistics centers, commercial projects, and residential roofing construction.
