Wakefield, Mass-based Natgun Corp. and El Cajon, Calif.-based DYK, Inc. merged on Jan. 4 to form a new company, DN Tanks, Inc. Natgun and DYK specialize in the design and construction of pre-stressed concrete storage tanks used for potable water, wastewater, chilled water and other liquids.

Initially, Natgun and DYK will operate under their existing names, as divisions of DN Tanks. As integration takes place, they will evolve into a single operating company. A four-member board of directors will lead DN Tanks, Inc.

The merger of the two companies results in expanded construction capacity, greater technical expertise, and proficiency in multiple types of tank designs to provide customized liquid storage solutions, according to the companies. With operations centers in Massachusetts, Texas and California, DN Tanks will serve clients nationally and internationally.
