1. A method for producing a fiber-reinforced polymeric continuous profile,
wherein the continuous profile comprises a core profile which is produced with the aid of a pultrusion process,
wherein at least one continuous strand having reinforcing fibers is integrated into the polymeric matrix of the core profile during the pultrusion process,
wherein the core profile is provided with an extruded outer, thermoplastic coating immediately after being shaped,
wherein the hardening of the core profile takes place using a dual cure method,
wherein a second curing process of the dual cure method is a heat cure, and
wherein an input of heat for the heat cure is via the application of a hot extrusion melt of the coating to the core profile.
