ABSTRACT:
A floor grating assembly is disclosed, which comprises tread rails arranged in closely spaced parallel relation and held by spacer bars. The spacer bars, which are notched, are inserted in alignment openings of preferably triangular shape in the tread rails. After insertion, the spacer bars are rotationally reoriented to a position securing the tread rails in spaced apart relation. Flange means extending along the lower edges of the spacer bars are locally deformable into locking notches formed in the alignment openings. The spacer bars are thus locked against rotation out of their operative positions. Manufacturing economies and structural improvements are realized.
