A screening module for a screening assembly includes a panel member having a periphery defined by a pair of opposed, parallel sides and a pair of opposed parallel ends. A mounting formation is arranged about at least a part of the periphery of the panel member for mounting the panel member on an underlying frame. A plurality of discrete aperture arrays are defined in a surface of the body member. A skirt portion circumscribes each aperture array, each skirt portion depending from a lower surface of the panel member. A reinforcing arrangement is arranged beneath each aperture array, the reinforcing arrangement being bounded by its associated skirt portion.
