Abstract
A combination section consisting of a base section (1) and a covering section (2). The covering section (2) is of an anti-friction material having a coefficient of expansion deviating from that of the material of the base section (1), and is divided between fastening points into partial lengths (4). The partial lengths (4) are interconnected by deformable bridges (6). This makes it possible for the partial lengths (4) to expand essentially unhindered, independent of the expansion of the base section (1) to a different extent.
