Summary
There are a number of factors that contribute to hot-dip galvanized steel’s appearance that can lead to inconsistencies. However, it is possible to achieve high quality coatings that meet aesthetic requirements of Architecturally Exposed Structural Steel (AESS) when the designer, fabricator, and galvanizer work as a team. Clear, direct, and frequent communication as well as a detailed plan of best practices for each party will help to maximize appearance and minimize cost premiums to achieve hot-dip galvanized AESS.
