Vulcraft Corporation was incorporated on June 12, 1946, in Florence, South Carolina. At first the company manufactured steel products such as chain link fences, Quonset huts, outdoor movie screens and miscellaneous steel building supplies. To increase profits the company's then President, Sanborn Chase, decided that the company should manufacture its own bar joists which would be used in shopping centers, schools and office buildings. In 1962, Vulcraft was sold to Nuclear Corporation of America which would then become Nucor Corporation in 1972.
Nucor's seven Vulcraft facilities are located in South Carolina, Nebraska, Alabama, Texas, Indiana, Utah and New York. Vulcraft is the United States' largest producer of steel joists and steel deck products. Current annual capacity of all seven plants in the production of steel joists and joist girders is more than 685,000 tons.
Six of of Nucor's Vulcraft facilities also produce steel deck. Plants that produce steel deck are located in South Carolina, Nebraska, Alabama, Texas, Indiana and New York. Current annual capacity of the six plants in the production of steel deck is approximately 430,000 tons.
