PURPOSE:To improve the surface state of the rail without impairing its durability by forming a wall plate clamping part having a U-shaved section for clamping at least the fumetight wall of aluminum and sticking stainless steel sheets along at least both outer flanks and the back surface, thereby constituting the rail. CONSTITUTION:The body 3 of the rail 1 is provided with the channel-shaped clamping part 2 having the U-shaped section for clamping the wall plates. This body 3 is molded of the aluminum by die casting or extrusion molding. The stainless steel sheets 4 are stuck to both flanks thereof. The sheets 4 are bent by a slight size toward the rear surface of the body 3, by which the sheets are stuck to the base as well. The sticking is successfully executed by applying adhesives on the flanks of the body 3, adhering the sheets 4 thereto, then bending and press forming the lower side parts along the base of the body 3 by a press machine.
