La porte palière comprend un corps de porte. Le corps de porte est formé par un élément en forme de plaque qui est plié et possède une section de surface avant qui s'étend dans le sens de la hauteur de la baie de communication palière, une section de surface latérale côté tête de porte, et une section de surface latérale côté queue de porte. La section de surface avant s'étend dans le sens de la largeur de la baie de communication palière avec une surface externe qui fait face au côté palier. La section de surface latérale côté tête de porte s'étend du côté tête de porte de la section de surface avant vers le côté cage d'ascenseur. La section de surface latérale côté queue de porte s'étend du côté queue de porte de la section de surface avant vers le côté cage d'ascenseur. L'aire d'une surface projetée dans laquelle est projetée la section de surface latérale côté tête de porte dans le sens de la largeur de la baie de communication palière est plus grande que l'aire d'une surface projetée dans laquelle est projetée la section de surface latérale côté queue de porte dans le sens de la largeur de la baie de communication palière.
