Founded in 1852, Pencoyd Iron Works was one of the largest producers of structural iron and steel in the world with around 1,500 employees.

The factory complex stretched for over a mile along the banks of the Schuylkill River.

Pencoyd manufactured cutting-edge materials and components for bridges, buildings, ships, and railroads across continents.

Their largest projects include the Ellis Island Immigration Station, Chicago Loop Elevated Railway, and the PA State Capitol Building.

In 1902, J.P. Morgan acquired Pencoyd Iron Works to merge with the U.S. Steel Corporation.

In the 1940s, Pencoyd mobilized production for WWII and closed soon after, leaving the iconic steel legacy on our site today.
