Abstract (en)

[origin: WO9907964A1] The invention concerns a passable stair tread, in particular a stair tread made of an extruded light metal section, comprising a transversely streamlined moulding projecting parallel to a running plate surface and defining longitudinal channels. In the running plate surface transverse grooves are formed, transversely relative to the direction of the ledges, corresponding more or less to the longitudinal channels, and, between said transverse grooves, other grooves, all these grooves forming undulating recesses or slots. The longitudinal channels and transverse grooves define vertical projecting groups forming the flanks of the undulating recesses or slots.
