A beam structure for a paper, board or finishing machine is suited for use in all applications where, for instance, a doctor or a coating device or a measuring device needs to be supported on a cross-directional beam of a paper or board machine. The beam (50) has an inner and outer shell (52, 54) which are situated inside each other and which are supported to each other over some of their length, and that one shell is supported stationarily by its ends to the frame structures (62) of the said paper, board or finishing machine, and that one shell deflects when the beam is loaded while the other shell remains essentially straight.
