The company also manufactures a variety of other formed metal products, including parts for the Titan IV rocket motor.The company was named for its founder, Frederick Hilmer Rohr, who was born into an immigrant German family in 1896 and grew up in San Francisco. Rohr served as an apprentice in his father's sheet metal works by day and attended school by night. Upon discharge from the Navy after World War I, Rohr returned to his father's business, now in Fresno, where he developed a stamping process for forming metal trim on building facades.
