Abstract
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 () extending in a longitudinal direction of the drainage channel or of the manhole and, substantially perpendicular to this bearing face, a rail edge () on the inner surface () of which the cover can be placed and on the outer surface () of which a surface covering can be applied. To increase the strength, it is proposed that the bearing surface () and/or the inner surface () and/or the outer surface () is/are provided with beads () over the entire length of the rail ().
