  Hot-dip galvanization is one of the most effective methods for protection of the steel elements of scaffoldings from the corrosion [1]. Owing to galvanization, the durable zinc coatings, resistant to corrosion and to all types of mechanical damages are obtained. The latter property has a great meaning due to the fact that the scaffolding elements are assembled and disassembled many times during their use. The high requirements for the mentioned scaffolding elements in regard to mechanical resistance of the coatings have caused that the different methods of protecting the steel elements of scaffolding e.g. painting. are sporadically employed. The research in respect of hot-dip galvanization is mainly focused on galvanization technology, quality of coatings and the studies on the impact of material, surface and thickness of galvanized elements on the quality of galvanized coating. In the studies, the problems of the effect of hot-dip galvanization on mechanical properties of materials, from which the galvanized elements are made, have been almost completely omitted. The existing papers are fragmentary and the obtained conclusions are nonunivocal. For the examined steels, the authors of a part of the studies did not observe the effect of the hot-dip galvanization on the change in the mechanical properties of the examined steel samples [4]. In some papers, the mentioned effect was found [2, 3]. In paper [3], the results of the tests on the effect of hot-dip galvanization on the mechanical properties of two commonly used steels: St3S and 18G2A, were presented. In the mentioned publicatio[...]
