Bradys Bend Iron Company Furnaces
Why it's listed
Stone iron furnaces and the remains of a rolling mill stand on the west bank of the Allegheny River at Bradys Bend, Armstrong County, about a mile upstream from where Sugar Creek meets the river. The first furnace was blown in around Christmas 1840, and the rolling mill began production in January 1842, linked to the furnace by a railroad. The Great Western Iron Works began operating here in 1839, and under the Bradys Bend Iron Company the works became a major producer, credited with rolling the first T-rails made west of the Alleghenies. It grew into the leading railroad iron manufacturing center in Pennsylvania, supplying the Pennsylvania Railroad and the Illinois Central. Operations halted after the financial crash of 1873. The furnaces are regarded as a key remnant of early American iron production, and the site is locally called the cradle of the iron and steel industry in America.
Significance in brief: The site is argued to be the cradle of the iron and steel industry in America, having been a leading iron center in the mid-1800s. Its furnaces were early hot-blast furnaces, and the works produced the first T-rails made west of the Alleghenies. The company later became the leading railroad iron manufacturing center in the state.
