Screening arrangement

A screening panel comprises a peripheral frame consisting of a pair of mutually laterally spaced side members which are integral with a pair of mutually axially spaced end members The side members and end members define corners of the panel and and the peripheral frame where they meet. A plurality of mutually spaced ribs extend across the periphery of the panel to define a screening surface. The side members and end members are rectangular in cross-section, thereby defining substantially flat upper peripheral surfaces outer peripheral surface and lower peripheral surface of the peripheral frame and thus also the panel The panel includes locating recesses provided at or near to the corners and of the panel The panel also has separate securing recesses in the form of semi-circular grooves formed in the lower surface of the panel around the locating recess and concentrically therewith.
