The wooden profiled board (100) especially for laying together in a parallel arrangement when building terrace or balcony coverings on a substructure has on its point (1) and on its end (2) a paired compatible transition structure comprising a tongue (3) on one end of the profile and triangular or trapezoidal in cross section, and a groove (4) on the opposite end and conforming to the tongue. The tongue in cross section is mirror-image symmetrical and describes an equilateral triangle with equal sided legs, or may be non-symmetrical in cross section.
