In April 2007, private equity firm Audax Group purchased ARNCO Corp. and Dura-Line Corp., both leading manufacturers of (HDPE) conduit, pipe, and conduit products and accessories. This merger led to the creation of A-D Technologies, an international company which markets under the ARNCO and Dura-Line brand names.  In 2011, A-D Technologies added Boreflex Industries and along with it, the Lamson Pipe brand.

Arnco History

In 1972, ARNCO Corp. began as ARNCO Flasher Equipment Company in Youngstown, Ohio, renting traffic barricades to utility companies. Several years later, in 1976, ARNCO expanded its product offering with the introduction of chemicals and equipment for utility installations. Then in 1985 Bob Smith purchased ARNCO and relocated the manufacturing facility and headquarters to Westlake, Ohio. Two years later, ARNCO moved its manufacturing facility and headquarters to Elyria, Ohio, and began manufacturing conduit.

Dura-Line History

In 1971, Dura-Line was founded in Middlesboro, KY., as a producer of plastic pipe for the potable water market. Ten years later, Dura-Line became the first manufacturer to develop an innovative conduit for the installation and protection of fiber optic cables. Dura-Line entered joint ventures with several international cable manufacturers in the mid-1990s to expand its international market share.
