This Automatic Double Layer Roll Forming Machine is designed for high-efficiency production of corrugated metal roofing sheets. The machine combines two independent roll forming layers into one rigid steel structure, allowing manufacturers to switch between two corrugated profiles without changing rollers. Equipped with a hydraulic cutting system and PLC touch screen control, it ensures stable operation, high accuracy, and long service life.
