SSP is marking its 100th anniversary year, celebrating a century of American-made manufacturing in Twinsburg. The family-owned company, an Ohio Manufacturers’ Association (OMA) member since 1989, has built a reputation for quality, safety and long-term investment, with all products made in one U.S. facility and a public centennial celebration planned for September. “SSP’s 100th anniversary is a testament to the kind of excellence, discipline and staying power that define Ohio manufacturing,” said Ryan Augsburger, OMA president. 3/27/2026
