Cast Iron Bollard Finishes: Powder Coating vs. Galvanizing for Durability

Which Finish Will Keep Your Cast Iron Bollards Looking Great for Decades?

Picture this: You’ve installed beautiful cast iron bollards along your driveway or garden path—only to watch them fade, chip, or rust within a few years. Frustrating, right?

The secret to long-lasting cast iron bollards isn’t just the metal itself—it’s the finish. Two popular options dominate the market: powder coating and galvanizing. But which one is right for your home?

Let’s break it down—no engineering degree required!

1. Powder Coating: The Colorful Protector

What Is Powder Coating?

Powder coating involves applying a dry, pigmented powder to cast iron bollards and then baking it for a smooth, durable finish.

Pros:

✔ Aesthetic Flexibility – Available in any color (matte black, bronze, even custom shades)
✔ Smooth Texture – No rough edges, perfect for homes with kids and pets
✔ UV Resistance – High-quality powders resist sun fading

Cons:

❌ Not Scratch-Proof – Heavy impacts can chip the coating (though touch-ups are easy)
❌ Thinner Protection – Less ideal for coastal areas with salt spray

Best For:

• Suburban homes with moderate weather

• Garden bollards where appearance matters

• Custom color-matching for cohesive outdoor design

2. Galvanizing: The Heavy-Duty Shield

What Is Galvanizing?

Galvanizing coats cast iron bollards in molten zinc, creating a rugged, corrosion-resistant layer.

Pros:

✔ Extreme Durability – Resists rust even in salty, humid, or snowy climates
✔ Self-Healing – Minor scratches “repair” themselves over time
✔ Low Maintenance – No need for repainting

Cons:

❌ Limited Color Options – Usually silver-gray (can be painted over, but adds cost)
❌ Rougher Texture – Not as sleek as powder coating

Best For:

• Coastal properties exposed to salt air

• High-traffic areas (driveways, gates)

• Long-term, no-fuss protection

3. Which Finish Wins for Your Home?

Still Unsure? Here’s a Quick Guide:

• “I want pretty bollards that match my garden décor.” → Powder coating

• “I need bollards that survive hurricanes and road salt.” → Galvanizing

• “I want both looks AND toughness!” → Galvanize first, then powder coat over it (yes, it’s possible!)
