The invention provides for a screening element which is predominantly of a synthetic plastics material and which has a screening surface formed by a plurality of ribs extending within a surround across the element, the ribs each being of a zig-zag configuration and the ribs being spaced from each other to define between them screening apertures, the ribs being resiliently deformable.

A screening element for screening a load of material and which is predominately of a synthetic plastics material and which has a screening surface formed by a plurality of ribs extending across the element, the ribs each being of a zig-zag configuration and the ribs being spaced from each other to define between them screening apertures, portions of adjacent ribs being closely spaced from and opposed to each other but not abutting against each other and other portions of adjacent ribs being further spaced from and opposed to each other so that the screening apertures defined between the ribs have alternate wide and narrow regions, the ribs being resiliently deformable independently of each other under the load of material to be screened and the ribs tending to straighten during deformation under the load.
