When selecting metal connectors and fasteners for your deck, be sure to use connectors and fasteners with the appropriate finish. Outdoor environments are generally more corrosive to metal because connectors are exposed to the elements. Depending on where you live, you'll need to use either ZMAX®, which provides a galvanized zinc coating, or stainless-steel connectors and fasteners. If you live along the coast or near bodies of water, it is recommended that you use stainless-steel connectors and fasteners for maximum corrosion resistance.
