Abstract

A method for manufacturing a beam (10) with openings comprising the steps of: providing two T-beams (20 1 , 20 2 ), the web (12a) of each of said T-beams having a respective free edge (22) describing an undulated line with peaks (24) and bases (26), the peaks being further essentially flat and parallel to a common axis; positioning the two T-beams (20 1 , 20 2 ) in face-to-face relationship so that the peaks (24) of their web edges come into contact and substantially coincide; welding the two T-beams together along their coinciding peaks (26) to form a beam with openings (18) located in its web. The undulated web edge lines (22) of the T-beams (20 1 , 20 2 ) are designed in such a way as to comprise a curvilinear line portion each side of each flat peak (26), such curvilinear line portion having a slope progressively approaching the slope of the flat peak (26).
