<p>The present invention refers to joints between profile sheets (1) used for roofing, the joints being perpendicular to the roof ridge, and to providing support in the ridge direction for the profile sheets. The invention is based on providing the profile sheet (1) comprising, as viewed from above, a designed transverse profiling (7), with such a shape of the longitudinal profiling (4) at the lateral edges (2, 3) of the profile sheet (1), which enables overlapping profile sheets adjacent to each other in the ridge direction, in such a way, that the folds (12) of the longitudinal profiling (4) overlap only partly. Thus a larger effective width is achieved as well as an improved support in the ridge direction of adjacent profile sheets (1).</p> |
