Frequently Asked Questions
How long will the galvanized coating last outdoors?
Hot Dipped Galvanized fasteners have a thick zinc coating that provides excellent outdoor corrosion protection — typically 20-50+ years in moderate environments. For coastal/marine use, consider stainless steel for longer life.
