Atkore Inc.
A maker of electrical conduit, cable, metal framing, and security products that keep buildings and critical infrastructure powered and protected. Its brands—including Allied Tube & Conduit, AFC Cable Systems, and Unistrut—are sold through wholesalers to contractors working on non-residential construction. The company grew out of Allied Tube & Conduit, founded in 1959 in Illinois and later spun out of Tyco in 2010. Its name is a play on "core," reflecting its place at the heart of the building trade, and its early invention of inline galvanizing for steel conduit remains a hallmark.
