CONSTITUTION:The supporting columns 11 and beams 12 are consisting of a plurality of elements 14 and are provided with protuberances 14B at one side and connecting holes 14C for inserting beighboring protuberances 14B at the opposite sides. Joints 13 are provided with the protuberances 14B, the protuberances 13B, inserted into the connecting holes 14C and the connecting holes 13C on the upper and lower sides as well as the side surfaces thereof. The joints 13 and the elements 14, 16 are made of composite material obtained by sintering the powders of alumina, copper or the like while the supporting columns 11 and the supporting beams 12 maintain the structure of the grate even when the grate is deformed by the weight of the corpse when it is cremated.
