The outer peripheries of the main bodies of the upper beam, lower beam and lateral columns are all coated with an opaque layer on which decorative articles are placed. The outermost faces is further wrapped by a transparent plastic layer by cold rolling or injection so as to enclose and fix the decorative articles therein. The upper and lower end sections of the left and right sides are formed with locking holes. The inner side between the upper and lower end sections are formed with several pivot holes. Each slat includes an elongated opaque sheet. Decorative articles are placed on two faces of the sheet. A transparent layer is integrally overlaid on the opaque sheet and the outer sides of the decorative articles to form the slat witha flat arch cross-section.
