Square pipe


The quadratic complete system made of aluminium sets new standards in roof drainage. It is ideally suited for use in modern buildings thanks to its simple and elegant design. The PREFA drainage system consists of twelve different components: square drain pipes with radii matched to the box gutters, various 72° pipe elbows, spout intersection and water collection box with square end.


The innovative aluminium products are convincing thanks to their sturdy design. The quadratic drain pipe with its 100 mm in lateral length is made of 1.6 mm thick extrusion profiles and with continuously captured retaining clamps (clips) on the back side. In addition to the new design, this concealed fastening with an M10 thread in particular underlines the minimalist appearance of the facade.


The perfectly balanced range of accessories supports a simple and quick installation on the building. *The PREFA square pipe is available in the powder coated colours 01 brown, 02 anthracite and 07 light gray, but can be supplied in all RAL colours. In the latter case, please take longer delivery times and surcharges into consideration.
