A grating ( 1 ) and a method of manufacturing the same using a pressing process are disclosed. The grating manufacturing method of the present invention includes the step of bending opposite ends of a metal plate to form a main surface ( 5 ) and supports ( 4 ), each having a predetermined height, the step of drawing a plurality of water drain slot formation portions of the main surface ( 5 ) to form slot frame parts ( 3 ), each having a predetermined depth, and the step of perforating bottoms of the slot frame parts ( 3 ) to form water drain slots ( 2 ). Therefore, the present invention provides a grating ( 1 ) that can sustain a relatively heavy load despite being manufactured through a simple pressing process, and a method of manufacturing the same through the pressing process.
