A reinforcing strip is adapted to be around helically around a cylindrical object such as a pipe (11), adjacent turns of the strip being arranged to partially overlap, the strip comprising longitudinal and transverse elements wherein the longitudinal elements (2-7) are spaced across the strip such that when the strip is wound into the helix, there is substantially even spacing between successive longitudinal elements of the strip, including in regions where adjacent turns of the strip overlap; thus the spacing of wires 6 and 7 in edge region III is such that on winding, wire 2 of opposite edge region II is located so as to give equi-spaced wires. <IMAGE>
