A suspension rail comprises a rail body (18) having a slide track (22,24) extending lengthwise of the rail, the slide track (22,24) being adapted to slidably support hangers thereon. The general novelty is that the slide track comprises two parallel tracks (22,24) of low friction plastics held in or by the rail body (18) and spaced by the rail body (18), so that a hanger (38) suspended on the rail contacts the rail only at the two tracks (22,24). Particular features are that the body (18) is a one piece extrusion of aluminium, and there are two rods (22,24) which form the tracks, these rods (22,24) being in grooves (18A,18B) in the body (18). The rods are firmly fixed by crimping part of the body (18) after the rods have been inserted in the grooves (18A,18B). Rods (22,24) of right angled triangular cross section are preferred as they can be inserted and clamped easier and held more securely than circular rods, and made to project further from the body than circular rods. The invention also provides an advantageous means (110) of providing jumpers for accommodating rod expansion joints and rail system switches.
A suspension rail comprising a rail body having slide track means extending lengthwise of the rail, said slide track means being adapted to slidably support hangers thereon, characterised in that the slide track means defines two parallel, spaced tracks of low friction plastics held in or by the rail body, so that a hanger suspended on the rail contacts the rail only at the two tracks.
