<p>The angle piece is for joining roofing components with mating profiled sections fitted over their ends and of plastic or metal, the faces of these sections being bevelled. It is inserted in these sections by means of two legs running parallel to them. The legs (38, 39) are narrower than the width of the sections, and the angle-piece (37) has a third leg (43) giving it an overall star shape. The third leg covers the join between the metal or plastic sections from the inside for at least part of its length. The first two legs can be roof-shaped when seen in sectional view.</p> |
