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
Prefalz® coils are perfect for use in standing seam roofing and cladding. Prefalz® strips are also ideal for use as flashing strips on PREFA small format components – suitable for various connections and flashings with dimensions of 0.70 × 1,000 mm (60 kg rolls).
- Available in 19 colours
- Our service: Profiling and rounding at our factory or directly on site
Tip: Strong winds blowing against mono-pitched roofs with double-lock standing seams can get noisy. To tackle this problem, we recommend using Prefalz® with a strip width of 500 mm. Sufficient sound insulation measures should already be taken into account when planning the roof structure.
Caution: Combining Prefalz® strips with other colour aluminium strips should be avoided at all costs due to the different paint qualities and folding abilities.
