Ours vs Theirs
Tiny Anvil Corten Comparison
High copper = stable rust patina
Low copper = patchy, uneven rust
Nickel for corrosion resistance
Nearly half the nickel content
Balanced carbon levels
Low carbon = softer, less reliable
Optimized silicon content
Low silicon = weaker structure
Consistent, predictable results
Unbalanced chemistry = unknown longevity
What the Lab Results Revealed
When we sent our Corten steel to the lab, the results confirmed what our customers already know: Tiny Anvil delivers uncompromising quality. Our steel sample contained more copper (0.240%), a critical element for developing a consistent and protective patina. It also showed nearly twice the nickel of the alternative—an essential factor in long-term corrosion resistance. With a well-balanced level of carbon and silicon, our material offers superior structural integrity and smoother weathering.
In contrast, the competitor's sample—commonly used by low-cost importers—had a lower copper count, inconsistent chemistry, and over-elevated manganese, which can lead to brittle finishes and unpredictable surface aging. The result? What looks like Corten at first, quickly breaks down into something far less reliable.
At Tiny Anvil, we don’t just match the industry standard—we define it. Backed by testing, trusted by professionals, and built to last in every season.
