Oil City Iron Works, Founded 1886

Rank: No. 4,478
Location: Corsicana, TX
Revenue: $35 million

The company that became Oil City Iron Works started in the 1860s and was originally called The Corsicana Manufacturing Company. It started out as a small machine shop that made parts for the cotton gin. Three local businessmen bought the small shop in 1886, and then leased it to an enterprising individual who rebranded as Oil City Iron Works, after the booming Texan oil industry. The company now manufactures a wide variety of iron castings, including valves, pumps, gas turbine and compression parts, and general oilfield equipment.
