Sistemi antikorozivne zaštite čeličnih konstrukcija prema standardu EN ISO 12944

Abstract

It is very important to protect steel structures against the influence of corrosion since it is one of the two biggest defects of steel structures. In addition to hot-dip galvanizing, coating is the most commonly used system for the protection of steel structures against corrosion. It is practically irreplaceable in cases where use of the hot-dip galvanizing is not possible. In this paper all relevant standards, with emphasis on SRPS EN ISO 12944 as most important for coatings usage, are shown. Terms of corrosivity categories, methods and preparation grades of steel surfaces, methods for coatings applying and measurement of their thickness, as well as which coatings type can be used for corrosion protection of steel structures are explained
