Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. The term is technical and identical.
Connotations
Identical technical connotations. Historically, 'iron' might evoke earlier 19th-century construction, while 'steel' is more modern, but the term 'structural iron' precisely denotes the material.
Frequency
Equally low frequency in both dialects, confined to engineering, construction, and historical preservation contexts.
