1 The colours P.10 stone grey, P.10 sand brown, P.10 rust brown, P.10 patina green, natural oak, grey oak, walnut, patina grey and plain aluminium reflect natural tones and are therefore subject to slight variations in colour, which give the products their unmistakable character.
3 Metallic colours may vary in shade.
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. Furthermore, the colours P.10 stone grey, P.10 sand brown, P.10 rust brown, P.10 patina green, walnut, grey oak, natural oak and patina grey reflect natural colourings that are composed of several colour tones.
- 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.
