Abstract: A grate bar for an incinerator having a grate bar base body and a high temperature resistant cover plate covering the grate bar base body at least on a surface portion which in operation points to a combustion chamber. The cover plate is separated from the grate bar base body by a thermal insulating material. In the grate bar base body a cavity is inserted in a side pointing to the cover plate and/or in the cover plate in the side pointing to the grate bar base body, which cavity is at least partially filled with a ceramic fiber insulating material. The invention further relates to a method for producing such a grate bar.
