An impact beam () comprises a polymer matrix and a reinforcing structure, the structure comprises a number of metal reinforcing cords () and non-metal elongated binding elements () or non-metal coated elongated binding elements arranged between the cords for holding the metal reinforcing cords together. Each of the metal cords has a metallic cross-sectional area Ametal, and the ratio of the metallic area Ametal to the area of the circumscribed circle (TTdcord2/4) is at least 0.60. The metal cords further have a non chemically binding with the matrix, and non-metal elongated binding elements or non-metal coated elongated binding elements have a chemical bond with said polymer matrix. By not having a mechanical interlocking and a non chemically binding with the matrix, the whole metal cord is stressed and not a local point while in the latter case the metal cord would locally break due to the very high impact forces. Therefore, the structural integrity of the impact beam as subject of the invention can be improved significantly during and after impact.

A flexible hose or pipe () is reinforced by means of at least one flattened steel wire () with natural edges. The steel wire has a thickness-to-width ratio t/w below 0.95, a tensile strength Rexceeding 3500&#x2212;2000&#xd7;d, where d is the diameter of a circle having the same cross-sectional surface and where Ris expressed in Mpa and a permanent elongation at maximum load Aof at least 0.70%. The flattening of the steel wire () allows to recuperate ductility which has been lost as a result of the drawing until the final tensile strength R.
