Hot-Dip Galvanizing of Steel Structures

Newer research on the morphology of coatings has shown that currently available publications on hot-dip galvanizing contain incorrect information about the Fe-Zn system. Hot-Dip Galvanizing contains practical information useful not only for researchers in hot-dip galvanizing, but also for engineers, designers and inspectors. The book draws from the empirical experience and research of the authors, complementing the current state of knowledge of morphological variations of the coating and causes of coating delamination. The book includes chapters devoted to qualitative tests of the coating and to methods of making corrections. A section describing the principle of protecting steel against corrosion through zinc coating is also provided along with an extensive chapter on principles of good design for hot-dip galvanizing. The chapter related to the safety of hot-dip galvanized steel structures offers a new hypothesis about the mechanism of nucleation of LMAC cracks during hot-dip galvanizing and enriches the knowledge about the phenomenon.
