The invention relates to a high-temperature-resistant grate bar (2) for a grate of a combustion furnace, in particular a waste incineration furnace, the surface of which faces the waste bed consists at least partially of a ceramic layer (3). The grate bar is characterized in that the ceramic layer (3) consists of a plurality of ceramic elements (5) which are embedded in the spaces (6) of a lattice-like metallic frame structure (4).
