Latrobe Foundry Machine & Supply Company was founded in 1933 by Louis C. Steiner as a cast iron and steel manufacturing and machining operation.
In the 1960s, the Foundry expanded into aluminum manufacturing, then gradually changed its focus exclusively to aluminum production. The Foundry’s manufacturing facility is located in Whitney, Pennsylvania.
Today, the Foundry manufactures and machines high-quality threaded and flanged aluminum pipe fittings in numerous stock sizes and styles, including both standard and reducing fittings. Latrobe Foundry products are used in a wide variety of businesses, including the agricultural, chemical, construction, and marine industries.
