a vehicular body panel or component part having a reinforcing backing plate reconciled to a part of a blank material at a position wherein a bending formation is implemented . the backing plate has one or more apertures formed in at least one lateral raw at a location equivalent to the position of the bending formation . when forming the blank material and the backing plate concurrently by a bending operation , the backing plate becomes intimately associated with the blank sheet to avoid the backing plate from locally separating from the blank material and from forming a gap relative thereto , with a resultant improved product quality .
