A reinforcer 130, 230, 330, 430, 530 of a material rich in elasticity is joined to an inside portion 114, 314, 317 of a stone bar 110, 310 of an L-shaped cross section. A groove 115, 315 is formed on one flat surface 112, 312 as an outside exposed surface. The groove is attached with a strip 121, 221, 321 as a coloring material which is made of a synthetic resin or synthetic rubber or the like of a color different from a color of the stone. Thus, a stone finished corner can be given a good strength and a user is prevented from slip on steps of stairs. <IMAGE> |
