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.
Main Components
| Decoiler | Holds and feeds steel coils smoothly into the line |
| Leveling System | Ensures flat, uniform material before forming |
| Roll Forming Unit | Precision-engineered rollers shape steel into different profiles with accuracy |
| Hydraulic Cutting System | Provides fast, clean, and burr-free cuts to required lengths |
| Control System (PLC + Touch Screen) | User-friendly interface for automatic operation and easy adjustments |
| Output Table | Collects finished products for efficient handling and packaging |
| Shrinking Device | it can reduce the port of the downpipe to facilitate lapping |
| Bending Device | The device can be bent into the desired arc of the downpipe. It can be bent up and down or left and right |
Key Features
- 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.

Applications
Residential Rainwater Systems
Downspouts are a standard component in residential buildings. They collect rainwater from roof gutters and direct it safely away from the foundation. Proper drainage helps prevent soil erosion, basement moisture, and exterior wall damage.
Commercial and Public Buildings
In commercial projects such as office buildings, shopping centers, and schools, drainage systems need to handle larger volumes of water. Downspout roll forming machines allow manufacturers to produce durable pipes that meet project requirements for size, strength, and consistency.
Industrial Facilities
Factories, warehouses, and industrial plants often have large roof areas that require efficient drainage solutions. Roll formed downspouts provide the capacity needed to handle heavy rainfall while maintaining structural stability.
Metal Roofing Systems
Downspouts are an integral part of metal roofing systems, working together with gutters to form a complete water management solution. By using roll forming machines, manufacturers and contractors can produce matching components that ensure compatibility between gutters and downpipes, resulting in smoother installation and a consistent overall appearance.
