White rust is superficial and doesn\u2019t affect<br \/>\ncharacteristic of the material. Light straining disappears with weathering.

The necessary ventilation conditions must be provided or heated<br \/>\nto a temperature that will prevent condensation of the moisture in the stored air. The relative humidity of the<br \/>\nstock should not exceed 75%. If adequate ventilation is not provided in stock areas, galvanized materials should<br \/>\nbe stocked in a separate place where ideal conditions can be established.<br \/>\n*To avoid excessive condensation of air in storage areas, especially in winter, the daytime temperature difference should be maximum 10 \u00b0 C.<br \/>\n*Galvanized materials should not be stocked for a long time; for this reason, customers should be warned that<br \/>\nthe waiting period should not exceed 2 months after delivery. The water or humid air entering the package<br \/>\nduring loading and transportation will be imprisoned and will cause white rust in a short time. This phenomenon<br \/>\nis one of the most important factors in the formation of white rust.<br \/>\n*Materials must not get wet during transportation. The vehicle must be completely covered with dry and sturdy<br \/>\ncanvas. Transport of galvanized products shall not be allowed with untransferable transport means<\/p>\n<p><span style=\"color: #000000;\"><strong>White Rust Cleaning:<\/strong> Since corrosion is a natural phenomenon, it is not possible to eliminate it entirely. However,<br \/>\nthe detrimental effect of corrosion can be reduced or controlled.<br \/>\nAll white rust layer is cleaned using a wire brush. By measuring the coating thickness it will be seen that the zinc<br \/>\ncoating in this area is preserved. Storage of the materials in a dry environment should be ensured.<\/span>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_separator][vc_column_text]<\/p>\n<p><strong>Galvanic Corrosion:<\/strong> Galvanic corrosion results from the electrochemical reaction that occurs in the presence of<br \/>\nan electrolyte when two dissimilar metals are in contact. The strength of the reaction and the extent of the<br \/>\ncorrosion depend on a number of factors, including the conductivity of the electrolyte and potential difference of<br \/>\nthe metals. The metal with less resistance becomes anodic and more subject to corrosion, while the more<br \/>\nresistant becomes cathodic. To avoid galvanic corrosion there should be isolation between metals and corrosion<br \/>\ninhibitor material should be added in the environment.<\/p>\n<p><a href=\"https:\/\/www.kiracmetal.com\/wp-content\/uploads\/2021\/11\/galvanik-korozyon-tablosu.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium\" src=\"https:\/\/www.kiracmetal.com\/en\/wp-content\/uploads\/2025\/01\/Ekran-g\u00f6r\u00fcnt\u00fcs\u00fc-2025-01-13-175012.png\" width=\"947\" height=\"675\" \/><\/a><\/p>\n<p><strong>Note:<\/strong> This table shall be treated as an aid for selecting solutions, it cannot totally predict actual<br \/>\nbehaviour.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][\/vc_column][\/vc_row]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][vc_column_text] CORROSION All metal surfaces corrode.
