PROFILIERTE PLATTE FUER BAUZWECKE.

摘要

The invention relates to a profiled sheet (3) for building purposes, especially roofing and facade sheet, said sheet comprising a normal profiling and having in addition, at least in certain sections, a corrugated microprofiling (4) deviating from the normal profiling. The microprofiling exhibits flattened and/or pressed-in areas in its crest, valley and/or flank sections resulting in that the thickness of the profiled sheet varies in a direction transversely of the longitudinal direction of the microprofiling which agrees with the longitudinal direction of the normal profiling. The flattened and/or pressed-in areas extend in the longitudinal direction of the microprofiling.
