【 摘 要 】

Aplication of hot-dip galvanized objects proves advantage full protection of steel components by zinc. Not only in industrial aglomeration but in this time ingeneral increased concentration of SO2 can be observed. SO2 and NaCl contribute to degradation of zinc protection in such a level that is necessary to provide protection of zinc cover against above mentioned corrosion activators.The test results completly proved high duality of the anti-corroison protection of the duplex Zn + Komaxit. On the photos it is possible to observe that in the aggressive enviroment salt is the pernament still protection by this technological procedure out standing under aspect of life – extention of component and constructions elements. The pernament protection is essential from the point of view begining as well as the prognose of the coroison.There is no doubt that expected of the anticorrosion quality of the protective Komaxit cover also very good mechanical charakteristics. Out of the test results it is clearly that the komaxit cover fixed on the protective zinc cover increase quality cover from the perspective of the functional as well as estetical.
