Phoenix Iron Works

The Phoenix Iron Works , located in Phoenixville, Pennsylvania, was a manufacturer of iron and related products during the 19th century and early 20th century. Phoenix Iron Company was a major producer of cannons for the Union Army during the American Civil War. The company also produced the Phoenix column, an advance in construction material. Company facilities are a core component of the Phoenixville Historic District, a National Register of Historic Places site that was in 2006 recognized as a historic landmark by ASM International.

Founded in 1790 to produce nails and purchased in 1812 by New Jersey industrialist Robert Waln, the Phoenix Iron Company produced pig iron, wrought iron, and other iron-related materials and end products. As the complex grew, it featured a huge blast furnace and puddling furnace, an adjacent iron foundry, warehouses, ancillary buildings, and associated equipment. In 1825, the company was the first to generate steam by burning anthracite coal. Other innovations followed. Engineers at the foundry invented a power-driven rolling method to weld and forge wrought iron, a process that enabled the iron company to begin producing cannon for the United States Army.
