Hot Dipped Galvanized Round Dock Washers
What are hot dipped galvanized round dock washers? Hot dipped galvanized round dock washers are oversized, thick round washers coated by dipping in molten zinc for a durable corrosion-resistant layer. Built for dock, marine, and heavy timber construction, the broad, stiff body spreads load and prevents pull-through while the galvanized coating stands up to water and weather.
Why hot dipped galvanized for dock washers?
Dock washers live in the harshest outdoor conditions, bolted into piers, docks, and waterfront timber that see spray, moisture, and weather, so corrosion resistance is essential. Hot dip galvanizing immerses the washer in molten zinc for a much thicker coating than electroplating, giving lasting protection against rust in marine environments. The oversized, thick round body spreads clamping load over a broad area, prevents bolt heads and nuts from pulling into treated timber, and resists cupping under structural torque. Pair galvanized dock washers with galvanized timber bolts and lag hardware. For continuous saltwater immersion, stainless offers the highest corrosion resistance.
Why choose hot dipped galvanized round dock washers
- Thick zinc coating: lasting corrosion resistance for marine use.
- Oversized and thick: broad, stiff bearing for structural loads.
- Prevents pull-through: stops hardware embedding in timber.
- Match coating: pairs with galvanized timber hardware.
Common applications for galvanized round dock washers
- Dock and pier construction
- Marine and waterfront timber joints
- Treated-lumber structural connections
- Oversized or weathered bolt holes outdoors

Hot Dipped Galvanized Round Dock Washers FAQ
Why galvanized for dock washers?
Dock washers are used outdoors near water, so the thick hot dipped galvanized coating gives lasting corrosion resistance against spray, moisture, and weather.
Should I match galvanized washers with galvanized bolts?
Yes. Pairing galvanized to galvanized keeps the whole joint at the same corrosion life and avoids galvanic issues, which matters in wet marine settings.
Are these good with treated lumber?
Yes. Treated lumber accelerates corrosion, so hot dipped galvanized dock washers and matching hardware are a standard marine choice.
