High-grade mild strip steel, hot galvanized with a process that combines zinc, a conversion coating and a clear organic polymer top coat to form a triple layer of protection against corrosion and abrasion. Has a low friction ID coating that improves the slip properties between conduit and wire. It provides easy bending, cutting and joining while resisting flattening, kinking and splitting. Reduces electromagnetic fields, effectively shielding computers and sensitive electronic equipment from the electromagnetic interference caused by power distribution systems. UL listed, meets ANSI C80.3.
