The Alan Wood Steel Company was a small, family-controlled integrated steel company, producing primarily steel sheets. The company was incorporated in Pennsylvania as the Alan Wood Company on January 23, 1929, and was renamed the Alan Wood Steel Company on February 16, 1929. It represented a reorganization and recapitalization of an earlier firm, the Alan Wood Iron and Steel Company. The Upper Merion & Plymouth Railroad, organized in 1907, connected all the elements of the Wood steel-making complex.

As a small producer, Alan Wood Steel was particularly vulnerable to the competitive pressure that hit the American steel industry in the 1970s. The firm went into receivership and steel operations were shut down on August 1, 1977. The company was reorganized as the Vesper Corporation and continues in the steel shelving business. Part of the rolling mill complex was sold to Lukens Steel of Coatesville, and the rest of the works was razed in late 1990.
