Cold Roll Forming Line For Safe And Stable Rainwater Downpipe Production

1. Production Line Overview

This production line serves metal profile suppliers and gutter manufacturers, offering safe, stable, and cost-effective downpipe production. It is ideal for medium-scale output and export to regions needing precise and robust round gutter pipes.

2. Profile Overview

The produced profile is a round downspout pipe made from galvanized or color-coated steel, typically 0.3–0.6mm thick. It features seamless appearance, strong drainage capability, and weather resistance. Commonly applied in roof rainwater systems for residential, commercial, and industrial buildings.

Process:

The line forms round downspout pipes from steel coils using a wall-frame, chain-driven roll former. After precise guiding and shaping, a hydraulic ring cutter delivers smooth, burr-free cuts. The setup ensures cost-effective, safe, and continuous production of drainage pipes with consistent roundness and surface quality.
