What are the required galvanization thickness for hot-dip galvanized cable trays
For the vast majority of applications, hot dip galvanizing can be simply specified using the following reference: Hot dip galvanized to EN ISO 1461 : 2022 by a member of Galvanizer Association (Galco, Sperrin). The ASTM A123/A123M specification defines the minimum requirements for zinc (hot-dip galvanized) coatings on iron and steel products—covering scope, coating thickness grades, finish/appearance, sampling, test methods, repair limits, and acceptance criteria. It is the primary quantitative metric that determines corrosion protection performance and service life. This standard contains coating thickness requirements as shown in table below which will. The thickness of the coating on hot-dip galvanized materials is not always the same. Several factors determine the thickness of the final coating. As hot-dip galvanizing experts, we at South Atlantic know how to ensure your materials receive a coating that is the proper thickness for your project.
