Steel fabricated at the Hamilton Bridge Works was used to build a number of local factories, such as International Harvester, Stelco, Firestone, Westinghouse and others. It also provided steel for such well-known projects as the Royal York Hotel in Toronto. After World War II, the company, now called Hamilton Bridge, became a division of the Bridge and Tank Company of Canada. Its highly skilled workforce produced steel mill equipment, mill cranes and general fabricated items, as well as bridges. Structural steel allowed early 20th-century industrial architects to build bigger factories with larger windows and doors. These new plants were more open, airy and well lit than 19th-century workplaces had been. They were also fireproof.
