The hot-dip galvanizing process is a relatively stable and reliable steel surface treatment solution to resist environmental corrosion. There are many factors that affect hot-dip galvanizing, such as: steel substrate composition, surface state (such as roughness), substrate internal stress, geometry The thickness of the base material has a greater impact on the thickness of hot-dip galvanizing, and generally the…
