Abstract: The profiled metal fibre with a substantially rectangular cross-section, also with bent fibre ends in the form of a clip, is used to stabilise, bond, attach or join materials and construction materials such as concrete, wood, paper and the like. The fibre edges of the fibre outer surfaces extending in the longitudinal direction of the fibre are designed as edge surfaces (2) oriented at an angle to the fibre outer surfaces in the manner of a bevel. The two wider fibre outer surfaces (3.1, 3.2) of the rectangular fibre are provided with V-shaped channels (4) extending in the longitudinal direction, wherein the edge surfaces (2) are provided with projections (6) and the V-shaped channels (4) are provided with end zones (5) that bound their longitudinal extent. The projections form anchoring heads and the end zones form anchor surfaces with respect to the material to be stabilised, bonded or attached.
