High Speed Double Layer Roofing Sheet Roll Forming Machine

This double layer roll forming machine is engineered for manufacturing two different roofing sheet profiles (such as 840 and 850 corrugated/trapezoidal panels) on one integrated machine frame. Equipped with an electric shear cutting system and precision forming rollers, the machine delivers high production speed, accurate length control, and smooth cutting edges. It is an ideal solution for roofing sheet manufacturers seeking higher efficiency and reduced equipment investment.
