In 1880, shipbuilder John Roach, proprietor of America's largest shipbuilding company,
John Roach & Sons, established the
Combination Steel and Iron Company to take advantage of the growing demand for steel products in the United States. Roach initially used the company to manufacture steel rails for the country's rapidly expanding railroad industry, but he soon discovered that America's existing steelmaking firms could not keep pace with nationwide demand, frequently leaving his new company unsupplied. Roach decided to rectify the problem by founding his own steelmaking firm, and on July 22, 1883, he incorporated the Standard Steel Casting Company on ten acres of land at Thurlow Station, on the Philadelphia, Wilmington and Burwood Railroad line, not far from his network of other companies in Chester. Salom became president of the company, while William E. Trainer, Richard Wetherill and John B. Booth became vice-president, treasurer and secretary respectively. The company gradually acquired a reputation for itself as a manufacturer of heavy steel castings and as a pioneer in steel casting experimentation. In 1888, for example, the company accepted an experiment to build one of the largest steel-cast guns ever produced in the United States to that time, a six-inch
rifled breech-loader weighing approximately 11,000 pounds. The weapon was manufactured using the company's open hearth process, while another company built a second weapon using the Bessemer process. In test firings, the Bessemer-produced gun failed after only the second round. The Thurlow-produced gun fired all ten of its test rounds without incident, but was finally failed after the barrel was found to have become slightly enlarged. The Thurlow Works management later had the gun mounted in its yard as testimony of "a courageous attempt to expand the uses of cast steel." Other large and difficult jobs taken on by Thurlow Works included castings for ship
anchors,
stern posts for
battleships and large industrial housings. In 1893, the company became the first in the United States to manufacture a complete cast steel frame for a locomotive, built for the
Baldwin Locomotive Works.
Later history In 1892, Thurlow Works was merged with several other steel casting companies including the Solid Steel Company of
Alliance, Ohio, to become the
American Steel Casting Company. The new company was headed by a prominent executive in the steel industry, Dan Eagan. In 1902, the American Steel Casting Company was itself merged with several other large steelmaking firms across the country to become one of America's largest steel casting companies,
American Steel Foundries, a specialist in the manufacture of
railcar frames and
couplings and other railcar parts. American Steel Foundries is known today as
ASF-Keystone, Incorporated. ==Footnotes==
