ABSTRACT:
A railing system is composed of vertically aligned metal tubes and cross-members which are metal tube rails. The posts are formed with round protruding bosses whose outer diameter (OD) is the same as the outer diameter of the posts. The rails also have the same outer diameter. The bosses and rail ends are brought into roundness, so that they match in a smooth circumferential seam, by round plugs forced into the bosses and rail ends. The post-rail joints may be welded in a circumferential weld; but preferably the posts and rails are joined by bolts connected to the plugs.
