Aluminum is, like any other metal, sensitive to environmental oxidation process. This spontaneous process would produce random spots, which would negatively affect the aesthetics of the profiles. It can be defined as the process of anodized as a controlled, accelerated oxidation and uniform of the most superficial layer of the profile, through an electrochemical process. The process of anodizing can be divided into three basic stages: pretreatment (degreaser + pickling), Anodic treatment (electrochemical process in which the aluminum becomes electrically positive and is immersed in an electrolyte) and post-treatment (sealed), to increase resistance to stains and corrosion of that layer. Outlook Email oftentimes addresses this issue. Treatment of lacquer consists of protecting the surface of the aluminium profiles with a coat of paint applied, either in powder or liquid. The designation of “Quality marine” is a process that improves the performance of the lacquer in very aggressive environments as first line of sea, industrial, etc., which consists in increasing the recess of the the material surface of 0.8 gr/m2 to 2 to 4 gr/m2, which benefits the penetration and grip of the depositions, while the “Fluorocarbonatados” or “PVDF” (lacquer based fluoropolymer 70: 30) are systems multilayer that offer excellent benefits to the aging and degradation of colour due to UV rays in environments of high aggressiveness. Both profiles such as aluminum plates used in construction are exposed to some risk of corrosion, which not only can have aesthetic but also structural consequences. For galvanic couple corrosion occurs when two metals are put in contact and both have different electrical potentials, which favors the behavior of a metal as anode and the other as cathode. To prevent galvanic pair place separators of plastics between aluminum and other metals, such as stainless steel for the anchorages and wicks.
