Abstract: A bumper beam assembly for a vehicle comprises a bumper beam having at least two round pipes, a bracket, first and second support members, first and second side frames, and a bracket formed into a rounded shape to match the external shape of the round pipes. The round pipes are arranged vertically and the sum of the diameters of the round pipes is smaller than the height of the bumper beam. The first and second support members have arc-shaped recesses which conform to the external shape of the round pipes and support the round pipes to connect the side frame to the round pipes, and one of the round pipes is positioned below a central point of the first and second side frames, and one of the round pipes is positioned above the central point.
