Because of the thinner coating of zinc oxide on electro-galvanized nails, they are the better choice for indoor projects, where they will have little exposure to corrosive materials like those found on pressure-treated wood, which should always be used outside.
Why do nails rust?
Everyday nails, screws, and fasteners are made of iron or steel, which are apt to rust due to time and exposure. The process of galvanization coats the hardware in a layer of zinc oxide. This protects the metal from rust and corrosion without diminishing its integrity.
