With great advances in technology and a fully globalized market, with a very strong competition between companies, the cost of manufacturing became a priority in companies that want to survive in the market, where the same processes are working hard on new material, this effort is to make their products more competitive. Since then, the analysis of this study is to evaluate the Galvalume® steel which is greater than  NBR 7008 with respect to corrosion resistance after the manufacturing process, and the process of manufacturing the flat plates forming tools of the lid panel silos of the same harm the finish, scuffs and scratches along the panel. With immersion tests to assess whether this type of aggression can negatively influence the corrosion resistance because this material is exposed directly to weather, with another aggravating factor is the cost of Galvalume® steel being on average 15-20% more expensive since in his chemical composition has used as zinc and aluminum galvanic protection as atmospheric drag, being an alloy with more additives the same has a more value-added to the steel, causing a burden to the manufactured product [1].
