Abstract: A screen assembly includes a frame having an outer perimeter and at least one inner support member, and at least one smooth surface affixed to the frame, where the smooth surface(s) have perforations. The frame may include a plurality of contact points extending upward from a top surface, and at least one smooth perforated screening surface is affixed to the plurality of contact points on the frame. In some cases the smooth surface comprises a perforated region and an erosion resistant region. Also, the perforations may have a shape that includes one or more corners. The smooth surface may be a perforated metal foil, sheet metal, and the like. Perforations may be apertures having one or more opening area sizes across the span of the screen assembly.
