Abstract

One of the most common and effective ways to protect metal structures from corrosion is hot-dip galvanizing, however, in a number of scientific articles it is noted that the technological process of this type of anti-corrosion protection can negatively affect the strength characteristics of a metal product.

The article reviews the literature sources that indicate the possible causes of a number of failures of the internal structure of steel elements as a result of hot-dip galvanizing. The analysis of the recommendations of normative documents (codes) on the implementation of anti-corrosion protection by hot-dip galvanizing has been carried out. Examples are given and the most probable causes of brittle fracture of steel elements as a result of hot-dip galvanizing are identified. Recommendations are given on the possible prevention of negative consequences associated with hot-dip galvanizing, both at the stage of manufacturing steel structures and at the stage of work on construction site.
