Corrosion Protection of Structural Steelwork by a Duplex Coating System

Abstract:

Steel constructions are an integral part of our lives, surrounding us almost everywhere. They are used for erection of various halls, bridge structures, railings etc. Each steelwork is more or less impaired by corrosion, respectively a certain level of corrosion aggressiveness of the environment. Corrosion is the cause of material degradation - referred to rusting. In order to avoid this unwanted phenomenon to the maximum extent possible, we use various methods and technologies protecting the relevant material and preventing from corrosion occurrence and development. This article deals with one of the methods aimed at corrosion protection of structural steelwork - duplex coating system that is assured by means of hot dip galvanizing followed by paint system application.
