An intermediate shell for a motor vehicle door, in particular a side door of a motor vehicle, is disclosed. The intermediate shell is produced at least in regions from a light metal blank by massive forming, preferably by forging.

Disclosed are an improved reinforcing bar and methods for manufacturing the same. The improved reinforcing bar is made from a high strength material, and has a circular or oval or elliptical cross section and deformation of the axis in a single plane or in multiple planes. The methods for manufacturing the improved reinforcing bar include a hot working process and a cold working process. The undulating/wavy bar with axis deformation can improve the anchorage of the bar in concrete and the bond strength without comprising any surface modifications. The amplitude and pattern of axis deformation of the bar can avoid stress concentration and its ill effects.
