High Efficiency Double Layer Roll Forming Machine

This double layer roll forming machine is designed to manufacture two metal roofing sheet profiles within a single heavy-duty frame structure. The upper and lower forming layers allow flexible switching between profiles, improving productivity while saving factory space and equipment cost.

With advanced cold roll forming technology and precision CNC machined rollers, the machine ensures accurate profile forming, smooth surface finish, and consistent panel quality. It is ideal for industrial buildings, warehouses, workshops, commercial facilities, and residential roofing projects.
