Rust Never Sleeps: Stainless Steel vs. Galvanized Hardware for Your Florida Dock

Living on the Emerald Coast means dealing with one of the harshest environments for construction materials: Saltwater.

When you are building a custom dock in Pensacola or Navarre, it’s easy to focus on the decking or the pilings. But the real "skeleton" of your dock is the hardware—the bolts, nuts, and rods holding it all together.

At Emerald Coast Marine Construction, we get asked constantly: "Is stainless steel really worth the extra cost over galvanized?"

Here is the breakdown of how these two metals handle our Florida waters.

The Contender: Hot-Dipped Galvanized Steel

For decades, galvanized steel was the standard. It is essentially steel that has been dipped in a layer of zinc. That zinc acts as a "sacrificial layer"—meaning the zinc corrodes so the steel underneath doesn't have to.

The Pros:

• Cost: It is significantly cheaper upfront than stainless steel.

• Strength: It has high tensile strength suitable for heavy marine construction.

The Cons:

• The Clock is Ticking: In a saltwater environment, that zinc layer will eventually wear off. Once it’s gone, the steel rusts rapidly.

• Maintenance: You will eventually see "bleeding" (rust stains running down your pilings) and will likely need to replace bolts within 10–15 years.

The Champion: Stainless Steel (304 & 316 Grade)

Stainless steel isn't coated; it is an alloy that contains chromium. This allows it to heal itself. When scratched, the chromium reacts with oxygen to form a protective layer. It doesn't just resist rust; it fights it.

The Pros:

• Longevity: In our local waters, high-quality stainless hardware can last virtually forever. It is a "one-and-done" install.

• Aesthetics: It stays shiny and silver. No ugly brown rust streaks down your beautiful new dock.

• Resale Value: A dock held together with stainless is a massive selling point if you ever list your waterfront home.

The Cons:

• Upfront Cost: It is an investment. The material cost is higher than galvanized.

The Verdict for Emerald Coast Homeowners

If you are building on a freshwater lake, galvanized is often fine.

But if you are on the Santa Rosa Sound, Pensacola Bay, or the Gulf, salt spray is your enemy. We strongly recommend upgrading to stainless steel. The cost of replacing rusted bolts 10 years from now—including the labor to tear your dock apart—is far higher than the upfront cost of doing it right today.
