A steel cord for the reinforcement of rubber articles, comprising a central base structure (1) composed of 2 to 4 steel filaments, and only one coaxial layer (2) composed of a plurality of steel filaments arranged around the central base structure, the steel filaments of said coaxial layer and the central base structure being twisted in the same direction at the same pitch, the steel filaments constituting the central base structure having the same diameter (dc), characterized in that steel filaments of the coaxial layer have the same diameter (dso) which is smaller than the diameter (dc) of the steel filaments in the central base structure, the ratio dc/dso being from 1.03 to 1.25. <IMAGE> |
