PROBLEM TO BE SOLVED: To provide a grating capable of decreasing the possibility of being clogged with stones, providing a slip preventing function, and not to increase the weight so much as that even if the mesh of lattices of the grating is reduced. SOLUTION: This grating is formed so that vertical sashes and lateral sashes are assembled with each other in lattice shape so as to form an assembled lattice. A plurality of T-shaped members 1 comprising a horizontal plate part 11 formed in a plate shape, disposed horizontally, integrally forming raised parts 13 and disposed at specified pitches on the upper surface thereof and a plate like vertical plate part 12 suspending from the center part of the horizontal plate part 11, formed approximately in T-section and made of metal are assembled with their horizontal plate parts 11 turned upward.
