With the (square) box gutter and the round PREFA downpipe or the equally square PREFA square downpipe (see image), rainwater is safely drained from your (PREFA) roof.
Advantages of PREFA’s box gutter
Malleable coating layer
Due to the coating of the aluminum coils in the coil coating process, the coating layer remains malleable and does not peel off - no annoying repainting and touching up.
Free of harmful heavy metal ions
Aluminum gutters do not release harmful substances.
Durable
Non-corrosive – because aluminium does not rust

Notes
- The RAL values stated are merely approximate values (~), some of which may differ vastly from the original PREFA color and, under certain circumstances, may not reflect the subjective perception of the color.
- Above all for color 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 colors may vary in shade.
- To identify exact colors for complementary components please consult original samples.
