Cast Iron vs. Steel Bollards: Which Lasts Longer?

Introduction: The Great Bollard Debate

You need sturdy bollards—but should you choose cast iron bollards or steel? It’s a classic showdown! Both materials have pros and cons, and picking the wrong one could mean rust, cracks, or costly replacements.

In this guide, we’ll break down durability, maintenance, and cost so you can make the smartest choice for your project. Plus, we’ll show why Hengsheng Casting (link to your product page) is a top choice for long-lasting cast iron bollards.

1. The Basics: What’s the Difference?

Before diving into durability, let’s clarify how these materials differ:

✔ Cast Iron Bollards – Made by pouring molten iron into molds, giving them a classic, rugged look.
✔ Steel Bollards – Often made from welded steel tubes, lighter but prone to bending under extreme force.

Fun Fact: Many historic European streets still use original cast iron bollards—some over 100 years old!

2. Durability Face-Off: Which Lasts Longer?

A. Strength & Impact Resistance

• Cast Iron Wins – Thicker and heavier, cast iron absorbs impacts better without bending.

• Steel’s Weakness – While strong, steel can dent or deform in high-impact zones (like parking lots).

B. Rust & Weather Resistance

• Cast Iron (When Properly Coated) – A powder-coated cast iron bollard resists rust for decades.

• Steel’s Risk – Even galvanized steel can corrode over time, especially near saltwater.

C. Maintenance & Long-Term Costs

• Cast Iron – Almost zero maintenance if powder-coated.

• Steel – May need repainting or repairs after harsh weather.

3. When Should You Choose Steel?

Steel isn’t always the loser! It’s better for:

• Temporary setups (easier to move).

• Ultra-modern designs (sleeker than cast iron).

• Budget projects (sometimes cheaper upfront).

But if you want decades of trouble-free use, cast iron is the smarter investment.
