History

Dayton Sure-Grip & Shore^[9] was founded in 1924^[10] by Art & Carl Kinnenger with help from Charles Danis and Fred Kramer. Carl Kinnenger held the patent on the snap tie design (to hold formwork together) and Dayton Sure-Grip & Shore was licensed to sell it in the U.S. out of their Downtown Dayton location.

In 1953, Danis Hunt Construction acquired Dayton Sure-Grip. After beginning bar support production in 1959, Sure-Grip, Inc is founded in 1960,^[9] and the company relocated to Miamisburg, Ohio. In 1975, Dayton Sure-Grip purchased C&M Chemical Co. out of Sycamore, Illinois, beginning their production of chemicals.^[11] After the purchase of Superior Concrete Accessories in 1982, the company changed their name to Dayton Superior Corporation.^[12]

A series of acquisitions followed, leading to international expansion^[13] (purchased Superior Concrete Accessories of Toronto and Cogan Wire Company of Montreal), and the purchase of Symons Corporation.^[14] Symons specialized in form systems, and manufactured shoring, formliners, and chemicals, drastically expanding Dayton Superior's number of products offered.^[15]

In 2006, Dayton Superior went public (NASDAQ: DSUP).^[16] Three years later, the company again went private, led by Oaktree Capital Management.^[17] The company then relocated to its current headquarters in Miamisburg, Ohio in 2010^[6]
