A variably mountable profile bar (10, 10') for use as a column, boom, cross member, strut, or the like for devices (30) is proposed. The profile bar (10, 10') is made of aluminum and, along two opposite side surfaces (12), has respective anchoring grooves (14) with a groove cross sectional area AN. A hollow channel (16) for electrical an pneumatic lines is embodied in the longitudinal direction. The hollow channel has a channel cross sectional area AK. The material of the profile bar (10, 10') has a material cross sectional area AM. The profile bar (10, 10') is characterized in that at least in sections, the ratio of the groove cross sectional area AN and the channel cross sectional area AK to the material cross sectional area AM is between 0.1 and 0.8. As a result, the profile bar (10, 10') is rigid and can be processed in a processing machine, as a result of which narrow tolerances can be achieved.
