This downspout pipe is a vertical pipe that is connected to a gutter system to direct rainwater from the roof of a building to the ground or a drainage system. Corrugation provides additional strength and rigidity to the pipe.

Downspout pipes are a critical component of a building's gutter system due to their purpose of carrying rainwater from the roof to the ground and away from the foundation of the building.

Corrugated downspout pipes are manufactured with a series of parallel ridges and grooves on their surface. This makes them less likely to collapse or bend under the weight of heavy rainfall or snow, and they are better able to withstand the pressure of the water flowing through them. In addition, corrugated downspout pipes also have a larger surface area than smooth pipes, which can help to increase the flow rate of water and reduce the risk of clogging. Corrugated downspout pipes are also easier to install and handle than smooth pipes due to their maneuverability during installation. This can save time and effort during the installation process-- reducing the overall cost of the gutter system.
