Galvanized nails, specifically nails that have undergone a process that coats the nails with zinc, are fairly common construction items. But, did you know double hot-dipped galvanized nails, while more pricey, are better protected, with more zinc, and so worth the money? Perhaps you didn’t realize that properly applied galvanized coatings can last a century. Although, today’s pressure-treated wood varieties can aggravate corrosion. For interested DIYers there’s lots to know, even about a simple commodity, like galvanized nails.
