The steel industry became the backbone of the Second Industrial Revolution in the United States primarily due to its pivotal role in infrastructure development and its wide-ranging applications in various sectors. The production of steel enabled the construction of railroads, bridges, and skyscrapers, which facilitated urbanization and economic growth. Innovations such as the Bessemer process significantly lowered the cost of steel production and increased its availability, leading to an expansion of industries that relied on steel for manufacturing machinery and construction materials.

This foundational aspect of the steel industry laid the groundwork for considerable advancements in transportation and industrial capabilities, making it central to the overall industrial transformation occurring during this period. The steel industry's influence on other sectors, such as automotive manufacturing and construction, further cemented its status as a driving force in the Second Industrial Revolution.
