The complete square system made of aluminium sets new standards in roof drainage. Due to its reduced and elegant design, it is ideally suited for use in modern buildings. The innovative aluminium products are not only particularly robust, but also visually eye-catching. Thanks to brackets on the back, the square tubes fit cleverly into the façade – without visible fastenings.
The PREFA drainage system consists of twelve different components: square drain pipes with radii adapted to the box gutters, various pipe bends with 72° degrees, gargoyle inlet and water collector box with angular outlet.
