Abstract: 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.
