A grate covering for an incineration grate of an incineration furnace having a combustion chamber, includes a plurality of metal grate bars, each having a surface facing the combustion chamber that includes a layer made of a temperature-resistant, corrosion-resistant and abrasion-resistant non-metallic material, wherein a thickness of the layer is minimally sufficient to bear pressure and thrust loading. The thickness of the layer is about 10 mm to 15 mm. For a forward feed grate, the layer on each metal grate bar is present only in a zone of contact with an adjacent metal grate bar, and for a roller grate, and wherein the layer is present on the entire surface facing the combustion chamber.
