The floor beam comprises an elongated beam (1) having an upper side (1a) and a lower side (1b) extending in the longitudinal direction of the beam (1) and two opposite long sides (1c). The beam (1) comprises a plurality of wooden slats (5, 5a) which are stacked along the height of the beam (1) to form a glulam beam, and a bottom flange (2) fixed to the lower side (1b) of the beam (1) and extending along the beam (1) in the longitudinal direction of the beam. The bottom flange (2) being fixed to the beam (1) with a plurality of elongate fastening elements (3). The bottom flange (2) is made of steel and projects from the beam (1) on each side of the beam (1), wherein each of the projecting parts (2a, 2b) of the bottom flange (2) has a width that is at least 20% wider than the distance between the long sides (1c) of the beam, and at least the upper wooden slat (5a) is made of a sort of wood that is harder than spruce.
