Abstract
A screed rail assembly for use in the construction of concrete slabs includes an elongated rail having a plurality of locking members that extend outward from the sides of the rail. The locking members provide a positive mechanical connection between the concrete slab and the screed rail, preventing structural damage due to external forces exerted against the slab. An elongated protective strip extends along the top surface of the elongated rail, further protecting the junction between the slab and the rail from damage due to external forces.
