In a storage rack, in which each of two columns has an outer wall facing outwardly and a side wall facing the side wall of the other column, a steel beam including two flange sections and an intermediate section extends between and is supported by the columns. Being fastened to an associated column, each flange section has a side plate adjacent to the side wall of the associated column and an outer flange adjacent to the outer wall of the associated column. Extending horizontally between the flange sections, the intermediate section is welded at each of its opposite ends to the side flange of an associated one of the flange sections. Being rolled from a steel sheet and defining a downwardly opening channel profile, the intermediate section has an outer wall, an inner wall joined unitarily to the outer wall so as to define an upper edge of the intermediate section, and a lower flange extending inwardly from a lower portion of the inner wall and having an upturned edge. As supported by and on the upturned edge of the lower flange of the intermediate section, a deck is confined against outward movement by the inner wall of the intermediate section and against side-to-side movement by the side plates of the flange sections.

Cette invention concerne un rayonnage dont chacun des deux colonnes comporte une paroi extérieure et une paroi latérale faisant face à la paroi latérale de la colonne opposée. Le rayonnage comporte également une poutrelle en acier à deux pattes de fixation et une pièce intermédiaire pour l'accrochage aux colonnes. Chacune des pattes de fixation comporte une aile intérieure contiguë à la paroi latérale de la colonne correspondante et une aile extérieure contiguë à la paroi extérieure de ladite colonne. Entre les deux pattes de fixation se prolonge la la poutrelle dont les deux extrémités sont soudées à à la pièce intermédiaire correspondante susmentionnée. Obtenue par laminage selon un profil en U dirigé vers le bas, la pièce intermédiaire comporte une aile extérieure, une aile intérieure solidaire de l'aile extérieure et définissant son bord supérieur et un rebord inférieur replié vers l'intérieur par rapport àl'aile intérieure et comporte un bord replié vers le haut. Supporté par le bord replié vers le haut du rebord inférieur de la pièce intermédiaire, l'étagère est empêché de glisser vers l'extérieur par l'aile intérieure de la pièce intermédiaire et de glisser latéralement par les pattes de fixation.
