A steel grating is provided to prevent damage to a grating by enhancing unity force between partition members and minimizing the flow of the grating. A first partition member(20) horizontally or perpendicularly partitions the inner side of a square edge member(10). A second partition member is curve-cut into a zigzag shape between the first partition members(30). In the lower part of the first partition member, a protrusion is formed. The second partition member is welded and fixed on the protrusion of the first partition member. The second partition member is curve-cut into a polygon shape or a semicircular shape. In the lower part of the edge member and the first and second partition members, the reinforcement member or the reinforcement recess is formed. |
