Decoiler: Holds and unwinds the coil of metal sheet
Feeding and Guiding Section: Feeds the metal into the roll forming section precisely
Roll Forming Unit: Series of rollers gradually shape the flat sheet into a round tube
Lock Seam: Bends and locks the seam mechanically (common in rainwater systems)
Welding Section (optional): High-frequency welding for stronger joints
