PURPOSE: A grating for a drainage way is provided to reduce manufacturing costs by simply manufacturing a body through a pressing process and to reduce the exhaust of toxic gas. CONSTITUTION: A grating for a drainage way comprises a body(10) and one or more support bars(20). The body comprises an upper plate(11), a pair of vertical parts(12), multiple drain holes(14), fixing pieces(15), and grooves(16). The vertical parts are bent from both sides of the upper plate. The drain holes are formed on the upper plate in a longitudinal direction. The fixing pieces are formed to be protruded downward from the drain holes. The grooves are formed on the fixing pieces at uniform intervals. The support bars are coupled to the bottom of the body and reinforce the structural strength of the grating. |
