Steel framed windows were made famous by the UK based company, Crittall Windows.

Crittal Windows was founded by Francis Henry Crittall, (1860-1935) who was an English businessman and philanthropist. He started the production of these windows in 1884 and quickly became the leading manufacturer of all steel framed windows and doors. With a little research you'll find lots of old ads and pics from the period- I especially love these vintage Crittall books.
