Information
PREFA gutters have been tried and tested for decades and their appeal lies in their well-thought-out, detailed technical solutions. Thanks to the proven surface treatment, they remain functional and attractive for many years. PREFA gutters are produced from powder-coated aluminium strips. Alloys according to EN 573 or DIN 1725 make up the basic material for this.
Advantages of PREFA gutters
- Surface treatment in a coil-coating procedure
- Corrosion-free and long service life thanks to aluminium
- Tested original quality
- Resistant to constant temperatures of between –30 °C and +80 °C
- Can be used creatively thanks to a range of 12 colours plus additional special colours (on request)
- Particularly low maintenance
- Comprehensive gutter accessories

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.
Technical information
The coating layer is malleable and protected against general chemicals and weather conditions. The coil-coating process is subject to strict quality controls.
In addition, the long-term behaviour is analysed in salt spraying, condensation and water immersion tests.
