Method for manufacturing a metal framework (1) for occasional furniture in which, so as to avoid extruding tubular sections which require dies with bridging pieces, open sections are manufactured by extrusion using dies without bridging pieces in order to constitute the tubular vertical girders (2) and the horizontal girders (4), and each tubular vertical girder is formed by securely joining two open sections, one of them (5) termed a connection section, and the other (6) termed a complementary section. <IMAGE> |
