There is provided a screening panel having screening apertures and which can be secured to a support frame side-by-side with similar panels to form a screen deck. The panel has ridges along two of its sides which project above the screening surface. The ridges form a channel which confines liquid flowing across the screen deck to flow across the screening apertures. Grooves extend through the ridges to direct liquid flowing across the screen deck directly into the screening apertures.
