The special alloy of haushaut fold ribbons allow for an easy shaping and transforming appropriate to any roof and façade shape. Due to its smoothness PREFALZ ® is easier to shape than most fold materials, thus enabling the designer to use it creatively in the roof and façade area. The minimum roof pitch of metal roofs is 3°; roof pitches 3°-7°, however, require special arrangements (e.g. rebate gaskets). Therefore, we recommend planning the substructure with a roof pitch of >7° (13 %). Processing is carried out according to the rules of the tinsmith and plumber trade.
