How does wrought iron’s tensile strength compare to steel in cantilevered outdoor sculptures?

When selecting materials for cantilevered outdoor sculptures, understanding the tensile strength of wrought iron versus steel is crucial. Wrought iron, known for its malleability and rustic appeal, typically has a lower tensile strength (around 25,000–30,000 psi) compared to steel (50,000–100,000+ psi). This makes steel a stronger choice for large, unsupported structures, as it resists deformation under stress better. However, wrought iron’s corrosion resistance and classic aesthetic often make it ideal for smaller, intricate designs where load-bearing demands are minimal. For outdoor sculptures, steel’s higher tensile strength ensures longevity in harsh weather, while wrought iron offers timeless charm with proper maintenance. The choice ultimately depends on the sculpture’s scale, design complexity, and environmental exposure.
