The specifications (ASTM A123, A153, and A767) give requirements concerning the minimum zinc coating for a given material class during the hot-dip galvanizing process. What is the thickness of a galvanized coating? When it comes to the specification of hot dip galvanizing, most contractors know that to be standards compliant, for example 7mm steel requires an average coating thickness of '85 microns'. The amount of coating can be specified by thickness or weight per surface area. This overview highlights notable updates across ASTM, AASHTO, ISO, and related guidance—and what they mean for specifying. Galvanizers Association can provide detailed advice on compiling your specifications, as well as reviewing design details to maximise the benefits of galvanizing your steel. Quite simple considerations will go a long way to ensure that your steel is processed quickly and efficiently: Listed below. Hot-dip galvanizing is done in accordance with long established ASTM specifications. EN ISO 1461:2022 (fourth edition), technically revising the third edition (EN ISO 1461:2009), is.
