A grate element (1) for a grate surface, e.g. in clinker cooler, comprises a top plate (5) which is shaped in the form of a box having a surface which is plane at one end, whereas at the other end it consists of in cross section downwardly curved slats (6) which, between them, form slots (9). The grate element further comprises a corrugated bottom plate (7) which is provided with lon- gitudinal rows of slots (11) and projections (13) rising in- to the slots of the top plate (9), and gas channels (3) which are defined by the underside of the slats of the top plate (5) and the upper side of the bottom plate (7), and open at the slots (9, 11) in the two plates (5, 7). Hereby it is obtained that the top plate of the grate element is ef- fectively cooled, that the pressure loss through the grate element is appropriately large, that the grate element is protected against falling-through of material and that maintenance work in connection with the replacement of grate elements is facilitated.
