A sheet metal component bent from a sheet metal blank having a triangular corner comprises a first and a second sheet metal member bent along bending lines from a base member to form two edges of the triangular corner. Two outer edges are weldable to each other to form a third edge. A recess extends into the base member, formed by a curved and/or polygonal first and second edge which protrudes towards the first edge. The second edge extends with a projection beyond a straight line defined by the bending line of the first sheet metal member. A projection tip is spaced from the first edge at least by a thickness of the sheet metal. When the sheet metal members are bent the projection is surrounded by the first edge and the recess is at least substantially closed by the projection.
