Inspection of Galvanized Steel 2.4.3

This visual inspection guide serves as a comprehensive resource for identifying surface conditions on hot-dip galvanized steel, allowing users to assess compliance with established specifications.

Newly formed hot-dip galvanized coatings may exhibit a range of appearances and surface conditions. It is important to note that many of these conditions are predominantly cosmetic and do not adversely affect the corrosion protection afforded by the coating. This guide provides clear criteria for recognizing various surface conditions, elucidating their causes, and determining their acceptability in accordance with ASTM specifications.

In addition to visual inspection criteria, the guide includes supplemental information and videos focused on the touch-up and repair of hot-dip galvanized steel, along with a detailed overview of specification requirements.
