Hot Dipped Galvanized USS Flat Washers

Hot dipped galvanized vs zinc plated washers

Hot dip galvanizing coats the washer by immersing it in molten zinc, building a much thicker, more durable zinc layer than electroplating. That thicker coating resists corrosion far longer in outdoor, wet, and exposed conditions, which is why hot dipped galvanized washers are standard in exterior construction, decks, and structural steel. The wide USS pattern spreads load over a broad surface. Match galvanized washers with galvanized bolts and nuts so the whole joint shares the same coating and corrosion life. For maximum coastal resistance, stainless is the step up.

Why choose hot dipped galvanized USS flat washers

• Thick zinc coating: outlasts standard zinc plating outdoors.
• Wide bearing: USS pattern spreads load over a broad surface.
• Outdoor durable: for exterior and wet structural work.
• Match coating: pairs with galvanized bolts and nuts.

Common applications for hot dipped galvanized USS washers

• Exterior construction and framing
• Decks, docks, and outdoor structures
• Structural steel exposed to weather
• Wet and outdoor larger-fastener joints

Hot Dipped Galvanized USS Flat Washers FAQ

How is hot dipped galvanized different from zinc plated?

Hot dip galvanizing immerses the washer in molten zinc for a much thicker, more durable coating than electroplated zinc, so it lasts far longer outdoors.

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 between dissimilar coatings.

Is galvanized as corrosion resistant as stainless?

Galvanized handles most outdoor exposure well, but for coastal, saltwater, or the longest life, stainless resists corrosion better.
