A screen panel module for mounting on a screen deck frame for screening, separating and grading materials such as ores. The module comprises a stiff frame component for supporting a resiliently flexible screening surface provided by a panel component. Opposite sides of the panel component include depending flanges having ribs for seating in complementary grooves in sides of the frame component for removably mounting the panel component on the frame component. The module includes means such as ribs, grooves, beads or the like, preferable associated with both the panel and frame components for interengaging with fixing means for locating and fixing the module to a screen deck frame. Whereas the whole of a prior art screen module has to be exchanged when worn, the invention allows the exchange of one component of a module, namely the panel component, which component costs a fraction of the whole module.
