This double layer roll forming machine is specially engineered to produce two different metal sheet profiles: decorative bamboo-style panels and 840 roofing sheets. The machine integrates an electric cutting system, precision roller forming technology, and PLC automatic control to ensure high-speed, stable, and accurate production.
The dual-layer structure enables flexible switching between two profiles, reducing equipment investment while maximizing factory space utilization. It is ideal for manufacturers producing both decorative metal panels and roofing sheets.
