Advantages and shortcomings of hot dip galvanizing steel sheet. Galvanizing problems

Hot dip galvanizing steel sheet is one of the optimum steel corrosion protection method on economic and ecological indicators. But this method has the advantages, shortcomings and the related problems of galvanizing demanding the urgent decision. In this paper the most important advantages and shortcomings of hot dip galvanizing steel sheet are considered and solutions of some problems are offered. The offered solutions of existing problems of hot dip galvanizing can promote further improvement of production steel with zinc coating. Therefore, quality of a coating and term of operation of products after hot dip galvanizing will increase. Moreover, in this paper some prospects of development of production steel with zinc coating in the future are considered. Hot dip galvanizing is one of the most demanded steel corrosion protection method, which is applied practically in all branches of a national economy and the industry.
