Downspout Roll Forming Machine

Our state-of-the-art Downpipe Roll Forming Machine is a high-precision, automated production line designed for the continuous and efficient manufacturing of gutter downpipes (also called leader pipes or rainwater pipes) from pre-painted steel, aluminium, or other metal coils. This system transforms a flat metal strip into a perfectly formed, consistent downpipe in a single, seamless operation, revolutionising productivity for metal roofing, construction, and building materials companies.

This machine is the ideal solution for producing standard round or rectangular downpipes in various diameters and lengths, significantly reducing labor costs, material waste, and production time compared to traditional methods.

High Efficiency & Automation: Features an automatic uncoiler and cutting system for continuous operation with minimal manual intervention, dramatically increasing output.

  • Precision Engineering: Utilises a robust roll forming system to ensure consistent profile shape, tight lock seams, and superior dimensional accuracy.
  • PLC Control System: An intuitive touch-screen PLC (Programmable Logic Controller) allows for precise adjustment of production parameters, including pipe length, quantity, etc. Fault diagnostics ensure easy operation and maintenance.
  • Customizable Length: Integrated precision flying cut-off unit cuts the formed downpipe to pre-set lengths without stopping the line, ensuring clean, burr-free ends.
  • Durability & Reliability: Built with heavy-duty steel frames and high-quality components to ensure stable performance, low maintenance, and a long service life in demanding industrial environments.
