柵 refers to a fence or barrier in general, while 欄干 specifically means a railing along the edge of a bridge, veranda, or similar structure.
欄干 is the common compound meaning 'handrail' or 'balustrade', while standalone 欄 used alone in that sense is rare and mostly literary.
欄外 (the margin or blank space outside a text area) shares the kanji 欄 with 欄干 but has nothing to do with a physical railing.
