The plate web and profile element include a web frame with a plate welded at a side edge to a flange. The flange is in the form of a bulb body. The bulb body can project symmetrically or asymmetrically relative to a mid-plane of the plate. The bulb body, in cross section, includes a plane welding face welded to the side edge of the plate and a common face that is spaced and parallel to the plane welding face. The bulb body in cross section also includes inclined faces extending from the plane welding face at an obtuse angle (.alpha.) of approximately 100.degree. to 120.degree. with the side surfaces of the plate. The bulb body further includes opposite side edges that are parallel to the opposite side surfaces of the plate and intersect the common face and the inclined faces of the bulb body. Rounded corners are provided at the intersection of the side edges of the bulb body with the common face and the inclined faces.

[ What is claimed is:] [1.] A web frame comprising a web plate and a flange welded to each other, the web plate having opposite side walls and a welding edge extending across the opposite side walls, the flange being welded to the welding edge of the web plate and having a bulb body extending beyond the opposite side walls of the web plate, said bulb body, in cross section, having(i) a plane welding face portion welded to the welding edge of the web plate,(ii) a common face spaced from and parallel to the plane welding face portion,(iii) an inclined face extending away from each said opposite side wall and extending away from the plane welding face portion at an obtuse angle (.alpha.) of approximately 100.degree. to 120.degree. to each said opposite side wall of the web plate,(iv) opposite side edges parallel to the opposite side walls of the web plate, each said opposite side edge extending across a respective said common face and a respective said inclined face such that each said opposite side edge intersects one of the common faces and one of the inclined faces, and(v) rounded corners at the intersection of the opposite side edges with the inclined faces and the common face.
