The beam (30) has a U shaped body (46) comprising a horizontal base (48) and solid lateral walls (50, 50'), and a U shaped cover (52) oriented in a same manner as the body. The cover includes a base and curved edges (60, 60') whose ends are oriented upward, so that each curved edge comprises an outer surface flattened against or fixed to an inner surface of the walls to define a closed section with the body. The cover includes openings (54) for accessing inner side of the beam. The walls are flared, where dimension between the walls increases in a direction away from the base.
