The present invention relates to a grating, and, more specifically, to a grating which is capable of being easily manufactured by improving the structure thereof. The grating comprises: two vertical frames arranged to be separated from each other; multiple horizontal frames interposed between the vertical frames and arranged along the length directions of the vertical frames at regular distances; and intermediate units mutually coupling the vertical frames and the respective horizontal frames, wherein the intermediate units includes: upper and lower coupling parts formed to be dented at both ends of the respective horizontal frames; and upper and lower corresponding coupling parts respectively protruding from the sides of the vertical frames and respectively and forcibly fit to the upper and the lower coupling parts, wherein the sides of the vertical frames face each other. The horizontal frames and the vertical frames are coupled with a lattice type by the coupling parts and the corresponding coupling parts which are forcibly fit to each other, so that the horizontal frames and the vertical frames are easily coupled to each other by pressing the vertical frames to the respective horizontal frames placed between the vertical frames. |
