Xiamen Youdeli Industrial Co.,Ltd is one of the most professional square downpipe roll forming machine manufacturers and suppliers in China. Our factory has been specialized in the design, development and manufacturing of good quality products made in China for nearly 20 years. Welcome to try our customized service.
Products Overview
The Square Downpipe Roll Forming Machine is built for manufacturers who need stable, repeatable production of rainwater downpipes with clean geometry and tight tolerances. It forms flat metal coils into square or rectangular downpipes used in roof drainage systems for residential, commercial, and industrial buildings. The line is designed for continuous operation, combining forming, cutting, and optional end-processing in one workflow to keep output consistent while reducing manual handling.
With a rigid frame, precisely machined rollers, and synchronized transmission, the machine maintains straight edges and uniform corners along the full pipe length. It is suitable for galvanized steel, pre-painted steel, and aluminum coils commonly used in gutter and downspout systems. For plants handling multiple orders, the setup allows quick changeover between different pipe sizes without lengthy downtime.
Integrated Production Process
The production starts with coil feeding and leveling, followed by progressive roll forming to shape the material into a square or rectangular downpipe. Once formed, the pipe moves directly into the cutting section where it is cut to the preset length.
The same line can then perform additional operations:
Elbow Bending: forming curved sections for corners and drainage routing
End Shrinking: creating socket ends for easy pipe connection
Optional Punching: for fixing holes or installation features
By combining these functions, the machine delivers a ready-to-install product without secondary processing.
Key Advantages
All-in-One Efficiency
Combining forming, bending, and shrinking in one system reduces labor, saves floor space, and shortens production cycles.
Consistent Connection Quality
End shrinking ensures tight and uniform joints between pipes, improving installation speed and reducing leakage risks.
Stable Bending Performance
The bending unit maintains smooth curvature without deforming the pipe profile, ensuring a clean finished appearance.
Flexible Production
Suitable for different pipe sizes and lengths, with quick adjustments to meet varying project requirements.
Reduced Handling & Damage
With fewer transfers between machines, the risk of scratching or deforming coated materials is minimized.

PLC Computer Controlling System With Touch Screen
The PLC Computer Controlling System with Touch Screen integrates advanced automation to ensure precise operation and seamless control of the production process. Featuring components from leading brands such as Delta, Schneider, Siemens for the frequency changer, PLC, touch screen, and other key parts, this system guarantees reliability and high performance. The Omron encoder ensures accurate feedback for smooth operation and precise synchronization across the entire production line.
Multiple samples
Samples are an important part of our production process. Each sample undergoes strict inspection to ensure it meets design and quality requirements. We use the same materials and processes as those used in mass production to ensure that the actual results of the samples truly reflect the quality of the final products. Through the sample-making process, customers can intuitively experience the molding precision and performance stability of the equipment, providing a reliable basis for subsequent large-scale production. We are committed to providing customers with high-quality, precise products that meet the needs of different projects.
Cargo loading
Built for Real Production Needs
The machine is designed with practical factory operation in mind. Operators can control the entire line through a centralized system, with clear settings for length, quantity, and function selection. Maintenance points are easy to access, and the overall structure is built for long-term continuous use.
For companies looking to expand their product range or improve production efficiency, the Square Downpipe Roll Forming Machine provides a reliable and scalable solution that supports both volume production and customized orders.
