According to an embodiment of the present invention, a bumper beam made by roll forming a plate material comprises: a front surface arranged in the front by being formed to be bent in multiple stages; an upper surface formed as an upper end portion of the front surface extends to be bent backwards; a lower surface formed as a lower end portion of the front surface extends to be bent backwards; a rear surface formed as a rear end portion of the lower surface extends to be bent upwards, and bonded to one side of the front surface to form two spaces between the upper surface and the lower surface, and the front surface and the rear surface; and a seaming joining portion coupled by seaming an upper end portion of the rear surface and a rear end portion of the upper surface with each other.

    본 발명의 실시예에 따라서 판재를 롤 포밍하여 만들어지는 범퍼 빔은 다단 절곡 성형되어 전방에 배치되는 전면, 상기 전면의 상단부가 연장되어 후방향으로 절곡되어 형성되는 상면, 상기 전면의 하단부가 연장되어 후방향으로 절곡되어 형성되는 하면, 상기 하면의 후단부가 연장되어 상방향으로 절곡되어 형성되며, 상기 전면의 일측과 접합되어 상기 상면과 하면 및 전면과의 사이에 2개의 공간을 형성하는 후면, 및 상기 후면의 상단부와 상기 상면의 후단부를 서로 시밍하여 결합되는 시밍 결합부를 포함할 수 있다.
