A bow-formed bumper beam for a vehicle has a hat profile with a central flange (11), two webs (12,13), and side flanges (14,15). The beam has fastening portions (20,21) at its sides where the side flanges form fastening areas (30-33) for fastening the beam to the vehicle with the central flange facing outwards. The profile height of the beam decreases continuously from the fastening portions towards the centre so that the profile height is less than two third of the highest profile height at the fastening portions. The central flange is wider at its centre than at its fastening portions and has a stiffener in the form of an elongate depression (16) that extends from the centre of the beam towards the fastening portions. In the area between the fastening portions, the side flanges have bent edges (26,27) and in association with the beginning of the bent edges, the side flanges have transverse dents.
