Early in the 20th century, Scottdale was the center of the Frick coke interests. It had steel and iron pipe mills, brass and silver works, a casket factory, a large milk-pasteurizing plant, and machine shops; all of the aforementioned are presently defunct. Scottdale is notable for its economic decline from a formerly prosperous coke-town into an archetypal Rust Belt town. Duraloy Technologies, "a supplier of specialty high alloy, centrifugal and static cast components and assemblies" is the last remnant of Scottdale's steel related prosperity.
