In this paper a specific application of shape optimization related with finding the optimal values of the internal dimensions of wide flange steel profiles. Two different problems have been solved in this piece of research by using a computer code SAFO written by the authors. This software has a user friendly graphic interface which allows the user to be comfortable with the code. According with the results of the research work carried out new series of wide flange profiles more efficient than the current one are included in this paper.
