Title
(EN) STRUCTURAL BEAM AND THE METHOD OF MANUFACTURING SUCH A BEAM
(FR) ELEMENT PROFILE ET PROCEDE DE FABRICATION
Abstract
(EN)
A structural beam exhibits cross-sections of variable area along its longitudinal axis achieved by cold deformation (folding) of the side walls of an extruded shape.
(FR)
Element profilé présentant des sections transversales à dimensions variables situées le long de son axe longitudinal et réalisées par déformation à froid des parois latérales d'un profilé extrudé.
