Abstract

See full text

Rails for drainage channels or manholes are known on which a cover of a channel or of a manhole can be placed. The rail has a horizontal bearing surface (10) extending in a longitudinal direction of the drainage channel or of the manhole and, substantially perpendicular to this bearing face, a rail edge (11) on the inner surface (12) of which the cover can be placed and on the outer surface (13) of which a surface covering can be applied. To increase the strength, it is proposed that the bearing surface (10) and/or the inner surface (12) and/or the outer surface (13) is/are provided with beads (20, 22, 23) over the entire length of the rail (1).
