Rainwater Downpipe

The downpipe is a key component of the rainwater drainage system's vertical stack. It is designed for the organized drainage of rainwater and meltwater from the hopper or gutter outlet down to the surface drainage system or storm sewer, ensuring the protection of the building's facade and foundation from water damage.

The product is manufactured from high-quality galvanized steel, which boasts high mechanical strength and resistance to deformation. Depending on architectural requirements, the downpipes can be supplied in a classic galvanized finish or with an additional double-sided Polyester polymer coating, which significantly increases the service life of the metal in aggressive external environments.

Design Features:

• Protective Options: The optional Polyester polymer coating provides resistance to ultraviolet (UV) radiation and sudden temperature fluctuations, preventing color fading and corrosion.
• Installation Flexibility: The availability of standard 1.5-meter and 3-meter lengths allows for the efficient combination of elements for buildings of any height, minimizing material waste when adjusting the stack height.
• Joint Reliability: The precise geometry of the connection joints guarantees the watertightness of the vertical stack and ease of assembly without the use of specialized equipment.
