Full Automatic Steel Downspout Roll Forming Machine

         Collecting roof rainwater is an integral part of the falling water system, which is concentrated into the rainwater pipes laid below the ground. The steel downspout roll forming machine is used to produce downpipes for rainwater systems. The downspout making machine adopts new high-tech, owning higher speed and lower noise. All machines can be customized. It could be used to make the pipes in high speed. For this machine, we adopt middle plate weld machine frame to make sure machine working speed and steady.

Downpipe material can be divided into:

1. Metal pipes (such as cast iron pipes, colored aluminum pipes, copper pipes, colored steel pipes, etc.)

2. Plastic pipes (such as PVC pipes, etc.)

         Here is the downspout profile drawing and dimensions for your reference. This interlock design don’t need any welding, it can save cost in machine production.
