Abstract
The invention relates to a sheet metal plate, especially made of steel, for producing motor vehicle body components. In order to make the body component sufficiently rigid at highly stressed points in spite of using lightweight materials, the sheet metal plate (11) is provided with local reinforcement zones (13, 14). To this avail, the sheet metal plate (11) is joined together from at least two cut metal sheets (7, 9) with a straight seam (10). At least one of the cut metal sheets (7) comprises several parallel strips (2 to 6) having different strengths while each local reinforcement zone (13, 14) lies within a reinforced strip (2, 3).
