Dayton Superior

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] The stint in the public markets did not last long, as the company filed for Chapter 11 bankruptcy.[17] The company emerged from bankruptcy later that year with significantly less debt[18][19] and a new capital management group in Oaktree Capital Management.[20] The company then relocated to its current headquarters in Miamisburg, Ohio in 2010[6]
