ABSTRACT OF THE DISCLOSURE: A profile steel of an about U-shaped cross section, which has a profile bottom with webs and flanges slightly in- clined toward each other and extending in the direction to- ward the open profile side. This profile steel, which is particularly well suited as profile steel segment when pre- paring reinforcing frames in connection with the building of mine shafts and tunnels, has a profile bottom which at its longitudinal sides has steps directed to the open side of the profile. These steps merge with the above mentioned webs which in their turn at the ends remote from the steps end in flanges pointing toward each other.
