Looking at Buildings: Iron and Steel in Construction

Steel can be rolled into shapes, such as railway tracks, but it is far less brittle than iron and could improve upon its predecessors. Independent steel-frame buildings were pioneered in the United States in the 1880s but the technology did not appear in Britain until 1906 at the Ritz Hotel.Even then the possibilities were not fully explored.
