Abstract
An assembling method of a hidden interconnection arrangement of fence or railing is provided, wherein a downward force applied to a top wall of a lateral beam is able to press a bottom guider edge of a lower engaging arm downwards against a top edge of an engaging rail that generates a reaction force to enlarge a bottom opening of the lateral beam to allow the engaging rail to be engaged in an engaging recess and locked between an upper engaging arm and the lower engaging arm of the lateral beam while fasteners that fastened the engaging rails to a plurality of upright posts are hidden and concealed by the lateral beams and the pressing walls of the lateral beams press against flat surfaces of the upright posts respectively.
