Hot-Dip Galvanizing (HDG)
For more than 150 years, hot-dip galvanizing after fabrication has been specified to combat steel corrosion in the harshest environments throughout various markets. However, new technologies and creative chemistries evolve the specification and use of hot-dip galvanized steel constantly as new markets emerge. Once considered only as a means of corrosion protection, hot-dip galvanizing is now specified for an array of reasons including lower initial cost, durability, longevity, availability, versatility, sustainability, and even aesthetics.
Understanding the characteristics and performance of hot-dip galvanized steel will facilitate and increase the specification of the coating in applications where galvanizing will enhance the project. This section will answer the following questions:
