<p>The roofing component has lengthwise parallel humps (2) separated by flat horizontal portions (3, 4, 5) acting as gutters. The humps have embossed portions extending transversely and pressed into them at regular intervals, to form a series of partly cylindrical portions (7) the rear part of which is offset downwards in relation to the front part of the adjacent portion. The overall effect produces a roof section formed of traditional round Roman tiles.</p> |
