General Steel Industries, Inc. (GSI) was an American steel company that operated independently from 1928 to 1981. It was founded by two locomotive manufacturers and a foundry as General Steel Castings Corporation in Eddystone, Pennsylvania. The following year, it acquired the Commonwealth Steel Company, a critical supplier to the rail industry, and the year after that, completed its own modern steel foundry.2

The story

In 1929, General Steel Castings Corp. acquired the Commonwealth Steel Company, a Granite City, Illinois based maker of steel, steel castings, and railroad supplies that had been founded in 1901, and had become a supplier to railroad companies. Commonwealth Steel had manufactured large cast steel bolsters for passenger cars for exhibit at the 1904 St. Louis World's Fair, and designed and produced a one-piece locomotive bed in 1926. By 1928, "practically all locomotives and passenger cars built in the United States" were using Commonwealth products.

General Steel's purchase of Commonwealth included Commonwealth's foundry and its new General Office Building, completed in 1926, both located at 1417 State Street, Granite City, Illinois. After the Commonwealth Steel acquisition, General Steel had two divisions, the Eddystone Division in Pennsylvania and the Commonwealth Division in Illinois. Only the Commonwealth Division was operational; the Eddystone Division's plant would not be completed until 1930. The Illinois operation was commonly referred to as the "Commonwealth," and was located at 1417 State Street in Granite City. During World War II, the Commonwealth plant manufactured steel for armor and cast steel tank hulls and turrets, and employed about 5,200 people. After the war, the company returned to manufacturing locomotive castings in Granite City and earth-moving equipment in Eddystone.

Fortune magazine ranked the company 464, 481, and 441 in the magazine's Fortune 500 listing in 1962, 1963, and 1964, respectively. Employees numbered 3,650 in 1962, 4,200 in 1963, and 4,400 in 1964.

Discontinued operations

In 1964, declining demand for large steel castings and excess capacity from operating two foundries led the company to consolidate the Castings Division's operations at its Granite City plant at 1417 State Street in Granite City, Illinois. The Eddystone plant was sold to the Vertol Co. (now Boeing) and converted to the manufacture of helicopters and aviation components. The plant is still in use as of 2014.

Fortunes for both the St. Louis Car Division and the Castings Division began to fade in the mid-1960s. "The smooth, comfortable ride of the modern railroad passenger car is the direct result of General Steel's historic development of new designs of trucks with cast steel frames and bolsters" but the development of new designs would at least partially result in the end of St. Louis Car. In 1970, St. Louis Car won two large fixed-price contracts for rapid transit and commuter cars but "the complexity of new engineering and manufacturing techniques for cars of such advanced design was underestimated" leading to recording a charge of $6,400,000 in 1971 for the expected loss on fulfilling the orders. As the company's largest division at the time, losses at St. Louis Car sank the entire enterprise's net income into the red. At the Castings Division, the Granite City plant improved production efficiency and lowered its breakeven point but a strike from November 20, 1971 to January 17, 1972 completely halted production.

On December 14, 1972, management announced the company's Castings Division and its St. Louis Car Division were to be closed, and after the delivery of pending orders, the divisions' assets were to be liquidated (expected to occur in 1973). The reasons stated to discontinue operations at the two divisions included significant losses and competitive pressure. St. Louis Car incurred losses for seven of the previous eight years and "GSI lacks the financial resources needed to compete with several much larger companies which recently entered the transit car building industry."

The Castings Division had not produced satisfactory earnings for five years, lost about $3 million in 1972, and "was not competitive in most of its major markets and there were no prospects for future improvement of its position." The company recorded a charge of $31,173,000 for the anticipated cost of discontinuing the unprofitable divisions. The closing of the Castings Division ended the company's manufacture of steel castings, products the company had been producing since its founding. The five remaining operating units were: National Roll, Flex-O-Lite, Ludlow-Saylor Wire Cloth Division, Standard Pipeprotection, and Simplicity Engineering Company (a subsidiary).

General Steel continued operations at the Granite City plant until orders, pending at the time of the December 1972 announcement of the Castings Division's closing, were completed. The property at 1417 State Street, Granite City, Illinois was purchased by Granite City Steel, a subsidiary of National Steel Corporation, in 1974 and the property became known as the South Plant. Granite City Steel likely occupied the facility until the parent company's bankruptcy liquidation in 2003.

In 1971, General Steel's corporate offices were at One Memorial Drive, St. Louis, Missouri. In 1973, the company's offices had moved to 8474 Delport Drive (8400 Midland Blvd.), also in St. Louis, and the concern launched a new consulting services division, GSI Engineering, to design railcar and locomotive trucks and suspension systems, and to manage the licensing of company products that were in service in 50 countries.

Less than a decade later, when General Steel was acquired by Lukens Steel in 1981 for $66 million, it was a producer of steel, crushing and conveying equipment, reflective highway signs, and protective coatings for oil and gas pipelines.

Castings Division Plant remains

By October 2009, most of the buildings at the former General Steel plant, including the old Commonwealth foundry at 1417 State Street, Granite City, Illinois had been demolished. About half of the General Office Building, built by Commonwealth Steel in 1926, remains standing. On the north end of the property, there are still several buildings in use.
