A steel cord (20) adapted for the reinforcement of elastomer products, comprises a single core filament (22) with a core filament diameter Dand 3N layer filaments (24, 26) twisted around the core filament in the same direction and with the same step. N ranges from four to five. The 3N layer filaments is arranged in an intermediate layer of N filaments (24) having an intermediate layer diameter Dand in an outer layer of 2N filaments (26) having an outer layer diameter Dand the steel cord (20) has the following characteristics (D, D, Din mm): D≤D<D. |
