CA 2145510
A method of manufacturing galvanised open or closed steel sections eliminates the steps of pickling and rinsing. The manufacturing process is modified in such a manner that shot blasting of both sides of a strip of substantially flat steel occurs prior to a forming step in the process. After the forming process, the formed section is emersed in a flux solution.
La présente invention se rapporte à un procédé pour la fabrication de panneaux d'acier de configuration ouverte ou fermée permettant de supprimer les étapes de décapage et de rinçage. Le procédé de fabrication en question est modifié de manière à ce que les deux côtés d'un feuillard d'acier relativement plat fasse l'objet de grenaillage avant l'étape de formage du produit. Après l'étape de formage, l'article formé est immergé dans une solution de fondant.
