Q3: How does the hot-dip galvanization process protect the steel frame?

The hot-dip galvanization process involves immersing fabricated steel components in molten zinc at approximately 450 degrees Celsius, creating a metallurgically bonded zinc-iron alloy layer on the steel surface. This coating provides two types of protection: barrier protection that seals the steel from moisture and oxygen, and cathodic protection where the zinc sacrificially corrodes to protect the underlying steel if the coating is damaged. The galvanized coating thickness is specified based on the environmental exposure category, with heavier coatings for more corrosive conditions .
