A Double Layer Roll Forming Machine is a specialized roll forming equipment designed to produce two different metal sheet profiles from a single machine. This machine is highly efficient and space-saving, making it ideal for businesses that need multiple profiles but have limited floor space.

The machine typically features two layers of rollers — an upper layer and a lower layer — that can switch between profiles without requiring additional setup or downtime. It is a versatile solution for manufacturing roofing sheets, wall panels, or other metal profiles widely used in construction and industrial applications.
