A screening element 10 for screening particulate materials such as mineral ores of all types, shapes are a densities, as well as difficult to screen cloggy, and slabby materials. The screening element 10 has a screening surface 12 formed by a plurality of elongate zig-zagged shaped ribs 14. The ribs 14 are resiliently deformable and extend within the periphery of the element 10 in a chevron pattern across the element 10. The ribs 14 are spaced from each other to define between them rows of square screening apertures 22. The screening apertures 22 have sides 22.1 which are orlentated transversely at 90° to an axis 10.1 of the screening element 10; and sides 22.2 which are substantially aligned with the axis 10.1. The element 10 is divided into two rectangularly shaped portions 16, 18 by a centrally disposed straight rib 20. The ribs 14 extend, in the portion 16, at an angle A of approximately 315° to the axis 10.1; and in the portion 18, at an angle B of approximately 45° to the axis 10.1.
