Abstract: A unitary extruded, plastic screed track is disclosed for use in connection with concrete slab construction. The screed track includes two elongated, parallel side members disposed in substantially vertical planes in close, spaced-apart relationship. An interconnecting member extends between the spaced apart side members at a point intermediate the top and bottom edges of the side members so as to form an H-shaped cross section. An elongated, bonding member projects outwardly from not more than one of the side members for anchoring the screed track to the concrete slab which is cast in place on one side of the screed track. A pair of oppositely extending flanges project outwardly from the lower edge of respective side members for transferring load between the concrete slabs cast in place on opposite sides of the screed rail.
