The weldments are hollow and the bases include openings to the hollow of the weldments. The cross-section of the end portions of at least one of the channeled elements is smaller than the cross-section of a center portion of the at least one channeled element. A method of making a beam brake beam, comprising: obtaining two channeled elements each having a base and two vertical walls; separating an end portion of one of the walls from the base; removing a section of the base adjacent the separated wall; attaching the separated end to the end of the base; and, permanently joining the channeled elements. |
