La présente invention se rapporte au domaine technique des étagères pour marchandises, et fournit une poutre de portée, une poutre transversale, une étagère pour marchandises et un système d'entreposage qui sont utilisés pour résoudre le problème technique selon lequel une poutre de portée n'est pas facile à installer. L'étagère pour marchandises comprend deux poutres transversales espacées et des poutres de portée reliées entre celles-ci ; une partie terminale de chaque poutre de portée est pourvue d'une partie portante et de parties de limitation, et la surface inférieure de la partie portante est pourvue d'une surface de contrainte faisant face à une poutre transversale ; les parties de limitation sont reliées à des côtés de la partie portante, et un trou de limitation est formé dans chaque partie de limitation, et fait face à un côté de la partie portante. La poutre transversale comprend un corps de poutre transversale et des adaptateurs disposés sur le corps de poutre transversale ; la partie supérieure de chaque adaptateur est pourvue d'une surface de butée ; chaque adaptateur est pourvu de fentes de confinement ; des ouvertures des fentes de confinement font face à une surface terminale d'une poutre de portée ; une saillie d'ajustement de limitation est disposée sur la paroi de fente de chaque fente de confinement. Lorsque la partie terminale de la poutre de portée est insérée dans les fentes de confinement, les saillies d'ajustement de limitation s'ajustent dans les trous de limitation, et la surface de contrainte vient en butée contre la surface de butée de façon à limiter le mouvement de la poutre de portée par rapport à la poutre transversale. La présente invention peut réaliser une installation rapide de la poutre de portée, et présente une structure de liaison simple et un faible coût.
