How is galvanized steel different from traditional steel?
The difference is that galvanized steel features an added layer of zinc. While typically invisible to the naked eye, galvanized steel has a thin layer of zinc covering its surface. Traditional steel doesn't have this layer of zinc. Steel is considered galvanized if it's made with this extra layer of zinc.
Is galvanized steel expensive?
Galvanized steel is almost the same price as untreated structural steel. Stainless steel costs four to five times as much as galvanized steel and untreated structural steel. Niobium alloys are even more expensive.
