Long before Birmingham earned its nickname as the “Magic City,” a foundry and machine shop on 28th Street North was quietly building the heavy iron and steel components that powered industries far beyond Alabama’s borders. The Hardie-Tynes Company, founded in 1895 by William Hardie and William Tynes, operated for more than a century in the shadow of Sloss Furnaces, turning out equipment that found its way into everything from ocean-going ships to one of the most famous engineering projects in American history.
A photograph from the company’s erection shop, undated but clearly showing the scale of the operation, captures workers and massive iron castings inside the plant. It’s a glimpse into an era when Birmingham’s iron and steel industry was among the largest in the South, and when companies like Hardie-Tynes supplied the heavy machinery that other industries depended on to function.
From Ship Engines to Hoover Dam
Over its decades in operation, Hardie-Tynes built a reputation for large-scale, precision ironwork. According to published company records, the firm manufactured ship engines and propeller screws, supplying parts used in maritime construction. It also produced air compressors and equipment for public utilities, work that tied the company directly into the growth of American infrastructure during the 20th century.
Perhaps most notably, Hardie-Tynes produced valves and gates used in the construction of the dam now known as Hoover Dam, on the border of Arizona and Nevada. The dam remains one of the largest public works projects ever undertaken in the United States, and the fact that components manufactured in Birmingham helped make it function is a point of pride for those who track the city’s industrial history.
A Neighborhood Built on Iron
The Hardie-Tynes plant’s location near Sloss Furnaces was no coincidence. That stretch of Birmingham grew up around the iron and steel industry, with foundries, machine shops and furnaces clustered together to take advantage of shared rail access, labor and raw materials. Sloss Furnaces itself operated as a pig iron blast furnace for nearly a century before closing, and the surrounding district became one of the defining industrial corridors of the American South.
Companies like Hardie-Tynes were part of the broader ecosystem that made Birmingham a manufacturing hub, employing generations of iron workers, machinists and engineers. The heavy castings and precision machining done inside shops like this one required skilled labor and specialized knowledge that was passed down over decades.
The End of an Era
The Hardie-Tynes Company ceased operations in 2016, closing the book on more than 120 years of continuous manufacturing. Its closure mirrored the broader decline of heavy iron and steel manufacturing across Birmingham and much of the industrial South, as production shifted, technology changed and many of the region’s historic plants shut their doors for good.
Photographs like this one offer a rare window into that vanished industrial world, a reminder of the scale of the work once done in Birmingham’s foundries and machine shops, and of the far-reaching impact that Alabama-made equipment had on projects across the country.
