1. A double T-shaped piling wall profile made of steel, comprising:
two flange sections, each having an adjoining club-shaped connecting end section adapted to receive an interlock;
a web connecting the flange sections;
wherein, as viewed in cross-section, at least one of the two flange sections has a convex bulge disposed between the club-shaped connecting end sections, with the convex bulge increasing an average wall thickness in the flange section while the connecting end section maintains a constant dimension, with the increase in the average wall thickness being produced by hot rolling the piling wall profile.
