<p>Method for manufacturing an elongate structural element and a rigid shell structure integrated with at least one elongate stiffening element. The method includes the steps of providing a preformed, form-stable former (16), which has a hat profile with two inwardly directed, opposing flange portions (20), covering the former with a curable composite material to form an external hat profile (24, 26) having outwardly directed flanges (26), and integrating this assembly (16, 24, 26) with either a curable or preformed shell structure (10) of composite material.
