Founded on innovation.
And we haven't stopped since.

The Beginning

begin-imageOur company was founded in 1959 in Harvey, Illinois, where our corporate headquarters is currently located. Our original business, known as Allied Tube & Conduit, developed an in-line galvanizing technique (Flo-Coat) in which zinc is applied as tube and pipe are formed. The Flo-Coat galvanizing process, a patented technique, was the foundation for our low-cost manufacturing of fabricated metal products. In 1960, the company began operation with a single tube mill – producing half-inch electrical conduit at the unheard-of rate of two feet per second.

50 Years of Growth

Over the next 50 years, the company diversified, becoming an industry leader through growth, acquisitions and innovation. We design and manufacture galvanized steel tubing and pipe products that include electrical conduit, flexible sprinkler pipe, and light gauge steel tube sold under the brand names Allied Tube & Conduit, FlexHead, and Tectron Tube. We also manufacture various electrical support system products including strut channel, metal framing, cable tray systems and associated fittings sold under the brand names Unistrut, Power-Strut, and Cope. We also design and manufacture pre-wired armored and metal-clad electrical cable, flexible and non-metallic conduit, PVC and HDPE cable protection products. These offerings are sold under the leading brand names AFC Cable Systems, Eastern Wire and Conduit, Kaf-Tech, and Heritage Plastics.
