<p>A sheet metal exterior sheathing element particularly suitable as a roofing tile. The tile has inter-engageable channels on its opposing longitudinal sides, one channel (6, 7) being on the underside and the channel (9) on the upperside of the tile. A mounting tab (10) extends from adjacent the upperside channel (9) substantially co-planar to the body of the tile. The channels enable two tiles (1a, 1b) to be joined in an overlapping side by side relationship with their corresponding channel sections engaged. Each tile (1a, 1b) can be fixed to a supporting structure by their mounting tabs (10). A third tile (1c) can then be joined longitudinally of the first two tiles (1a, 1b) by engaging its underside channel (6) over and about their joined upperside channel sections (9). It can also be fixed to the supporting structure and the steps repeated to sheath a desired area.</p> |
