摘要

Production of a U-shaped semi-finished material made from metal comprises reducing an average U-bar (12) by cold rolling opposite U-sides (15) from a strip having a rectangular cross-section. An independent claim is also included for a chair rail and/or driving rod for a driving rod mounting made from the semi-finished material. Preferred Features: The U-sides are aligned on their whole length on the outer sides. The ratio of the thickness of the U-bar and the length of the U-sides is 1: 1.8-2.1.
