Information

The square, aluminium complete system sets new standards for drainage. Thanks to its minimalist and elegant design, it is ideal for use on modern structures. The innovative aluminium products are not only particularly robust, but also visually very eye-catching. Through brackets on the rear side, the square down pipe skilfully blends into the façade without any visible fasteners. The PREFA drainage system is made of up twelve different components such as square downpipes with radii corresponding to the box gutters, various downpipe elbows with a 72° bend, outlet connectors and a leader head with a square outlet.

Notes

  • The RAL values stated are merely approximate values (~), some of which may differ vastly from the original PREFA colour and, under certain circumstances, may not reflect the subjective perception of the colour. 
  • Above all for colour quality P.10, it is almost impossible to define values due to the surface structure.
  • Plain aluminium: The guarantee does not cover surface appearance alterations caused by processing and environmental influences. Follow the instructions.
  • Metallic colours may vary in shade.
  • To identify exact colours for complementary components please consult original samples.
