The strip forms a permanent edge, having embedding tissue joined to a flange and protruding beyond it in the transverse direction. A continuous external protruding edge (1) extends along the flange (2) or the join between two flanges including an angle (a). The tissue (3) is glued or welded to the flange inside surfaces. The thickness of the flanges can decrease continuously or in steps from the edge, and they can contain anchoring holes through which plaster, mortar or glue penetrates. They can be roughened on their surfaces on the opposite side to the tissue. |
