About Mesta Machine Company

The Mesta Machine Company, chartered on November 21, 1898, was a major manufacturer of steel mill equipment and machinery. Located in Homestead, Pennsylvania, on the banks of the Monongahela River approximately six miles upriver from Pittsburgh, Mesta eventually became the world's largest steel mill equipment manufacturing establishment under one roof. Mesta was an outgrowth of two earlier companies, Leechburg Foundry and Machinery Company and Robinson-Rea Manufacturing Company. George Mesta obtained controlling interest in Leechburg Foundry in the 1890s and then negotiated a merger with Robinson-Rea to create the new company, which he named after himself.

At the height of its success, Mesta employed over thirty-eight hundred people and sprawled over thirty acres. Mesta took advantage of the steel industry trend in the early 1900s that called for more mechanized steel making processes. As a result of this foresight, Mesta quickly became the top manufacturer of rolling mills, gas and steam engines for blast furnaces, forging presses, and machine-molded gears. The plant included laboratories, foundries, open-hearth furnaces, numerous mills, and separate departments for gear molding and ship shafts. The company sold equipment to iron and steel plants in Canada, Australia, India, England, France, Italy, and Japan.

With the collapse of the U.S. steel industry in the 1970s, Mesta Machine also suffered. In 1983, it filed for bankruptcy and was sold to Park Corporation, who divided it up into several separate manufacturing facilities for a variety of smaller companies such as Mestek and WHEMCO.
