Square Downspout Pipe Roll Forming Machine

Square Downspout Pipe Roll Forming Machine With Off-line Bending

1. Production Line Overview

This production line is designed for manufacturers in the construction and drainage sectors. It offers high automation, precision forming, and efficient production of square downspouts. With a focus on ease of use, customization options, and reduced waste, it’s ideal for clients looking to streamline production and deliver high-quality downspout systems.

2. Profile Description

This square downspout is made from pre-painted galvanized steel with a thickness of 0.5–0.6mm. It features a clean, modern square shape, offering both aesthetic appeal and functional drainage. Ideal for residential, commercial, and industrial roofing systems. It’s corrosion-resistant and can be customized with bending or shrinking functions for easy installation.

3. Production Process

3T Manual Decoiler → Guiding Device → Roll Forming Machine → Hydraulic Cutting → Output Table   Standalone bending unit.

The process starts with the manual decoiler for coil unrolling. The steel sheet then passes through the 21-roll forming machine, where it is shaped into a square downspout. The hydraulic cutting system ensures precise cutting to length, followed by a separate bending unit for shaping.

5. Key Focus

Complete Production Process
The production line offers a fully integrated process, including roll forming, cutting, and bending. It is highly automated, ensuring efficiency and precision throughout the entire production cycle.

Optimized Separation of Forming and Bending
The downspouts are primarily straight pipes, but curved sections are used for installation and corners. By separating the forming and bending stages, the production process is optimized, leading to improved overall capacity and efficiency.

7. Customization Options

This production line allows full customization of square downspouts, including adjustable dimensions for the width, height, and length. Bending angles can be customized to meet client-specific requirements, with both vertical and horizontal bending options. Additionally, the pipe ends can be shrunk for easier interlocking and seamless installation in various drainage systems.

8. Auxiliary Equipment

Upgraded Decoiler
The manual decoiler can be upgraded to a hydraulic decoiler for enhanced automation and easier coil tension adjustment, improving overall production efficiency.

Note: The line is also compatible with pre-coated (film-coated) steel coils, offering additional protection and decorative finishes for the downspouts.
