ABSTRACT:
A strand for reinforcing objects made of polymer material comprising at least one core wire and less than six outside wires arranged round it, the core wire having an outside diameter larger than the diameter of the circle tangent to each of the outside wires in the hollow space that remains free when their cross-sections have the highest packing density and smaller than the diameter of the outside wires, whereby the outside wires are made of carbon steel wire with a tensile strength of at least 2250-1130 log d N/mm.sup.2, d being the wire diameter in mm. The core wire has a tensile strength less than 2250-1130 log d N/mm.sup.2.
