Abstract
The invention relates to a glass fibre-reinforced, extruded plastics material hollow profiled strip for the production of window frames, glass doors, or the like. In order to be able to butt-weld profiled strips of this type together when producing the frame and to ensure a reliable bonding between the glass fibres and the plastics material of the profiled strips a synthetic resin is used as the bonding agent which causes this bonding, which synthetic resin has thermoplastic or thermoelastic properties and thus enables the glass fibres to be deflected during butt-welding and pressing together of the ends of the frame pieces.
