Stainless Steel vs. Hot-Dip Galvanized: Which Finish Is Best for Anchors?
When it comes to anchoring masonry veneers, choosing the right material finish is just as important as choosing the right anchor. The two most common finishes in the industry—Stainless Steel and Hot-Dip Galvanized (HDG)—offer different levels of corrosion resistance, cost, and performance.
In this post, we break down the differences between stainless steel and hot-dip galvanized finishes so you can make the right call for your next project.
Hot-Dip Galvanized Anchors
Hot-dip galvanizing is a process where steel is dipped into molten zinc, creating a thick, corrosion-resistant coating. It's widely used in construction for its affordability and decent protection against rust in most above-grade conditions.
Advantages
-
Cost-effective – significantly cheaper than stainless steel
-
Decent corrosion protection – ideal for many inland or mild climate applications
-
Widely available – used for a wide range of masonry anchors and ties
Limitations
-
Zinc coating wears off over time, especially in coastal, industrial, or highly humid environments
-
Not suitable for below-grade or marine environments
-
Not compatible with dissimilar metals like stainless steel (can lead to galvanic corrosion)
Best For:
-
General commercial construction
-
Above-grade, dry environments
-
Projects with tight budgets where long-term corrosion isn't a major concern
Stainless Steel Anchors
Stainless steel contains chromium, which forms a self-healing oxide layer that resists rust. It’s the premium choice for long-term durability in harsh environments and is increasingly required by code in high-performance or coastal applications.
Advantages
-
Exceptional corrosion resistance – ideal for coastal, industrial, and humid environments
-
Long-term durability – won’t flake, chip, or rust over time
-
Compatible with other stainless components – prevents galvanic reactions
-
Required by building codes in many coastal/seismic zones
Limitations
-
Higher upfront cost
-
Can be overkill in dry or interior applications
-
Must ensure full system compatibility (e.g., not mixing with galvanized components)
Best For:
-
Coastal or marine environments
-
High-humidity or freeze-thaw climates
-
Projects where long-term structural performance is critical
-
Government, institutional, or LEED-certified jobs
Key Considerations When Choosing a Finish
| Factor | Stainless Steel | Hot-Dip Galvanized |
|---|---|---|
| Corrosion Resistance | Excellent – long-term durability | Good – moderate protection |
| Cost | Higher | Lower |
| Environment Suitability | Harsh, humid, coastal, industrial | Dry, mild, inland |
| Code Requirements | Often required in seismic/coastal zones | Meets standard requirements |
| Compatibility | Must match with other stainless items | Must match with other galvanized components |
Our Recommendation
At Masonry Direct, we always recommend evaluating the environmental exposure and project lifespan when selecting a finish. For budget-conscious, inland commercial projects, hot-dip galvanized is a solid choice. But if you're building near the coast, in high-humidity zones, or simply want maximum durability, stainless steel is the way to go.
When in doubt, it’s better to over-specify than deal with corrosion-related failures years down the line.
