Abstract: A tubular hollow profile, particularly a spacer tube for the production of spacer frames for insulated glazing, has a profile wall. The profile wall is configured to be double-walled and has an outer wall made of metal, particularly stainless steel or aluminum, and an inner wall made of plastic, which are connected with one another, preferably in firm, i.e. non-displaceable manner. A device and a method for production of the hollow profile are also provided.

Abstract: The present invention relates to a spacer tube (1) for the production of spacer frames for multi-pane insulated glazing having at least two glass panes, having a tube wall (2) that has a visible wall (6), a bottom wall (7) that lies opposite the former, and two side walls (8) that lie opposite one another, for a connection with a glass pane each, whereby at least one of the two side walls (8) is cold-strengthened, at least in partial regions, to increase the bending stiffness of the spacer tube (1), as well as a multi-pane insulated glazing having a spacer frame having at least one such spacer tube (1), and a device and a method for production of the spacer tube (1).
