A unibody structure for a screen assembly for a vibratory separator, the unibody structure, in certain aspects having an integral body member with a portion having a plurality of spaced-apart openings in a pattern of a plurality of spaced-apart screening openings and including a pair of spaced-apart integral side members made of folded portions that form the pair of spaced-apart integral side members, a pair of spaced-apart integral end members made of folded end portions, the pair of spaced-apart integral end members each with a first end member and a second end member, the first end member configured with a shoulder support portion for sealingly abutting a screen ledge end of an adjacent screen, and the second end member configured with a ledge portion for sealingly abutting a shoulder portion of an end of an adjacent screen, and the plurality of spaced-apart openings of the integral body member defined by a plurality of spaced-apart strips, each adjacent pair of the plurality of spaced-apart strips defining a space through the integral body member and having a length and independent of and not connected to the other strips along its length. In one aspect there is screening material on the unibody structure.
