Thanks to it’s properties Prefalz is more pliable than most comparable hard metals. Architects can use it in many creative ways as roof and wall applications. PREFA recommends a minimum roof pitch of >7° but in accordance with national guidelines a roof pitch of >3° is feasible (see PREFA Installation Instructions).

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.

Colour details

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

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.
