Electrunite® Color Electrical Metallic Tubing (EMT)

Using Nucor Tubular Product’s Color EMT is the safest and most effective way to quickly identify and trace designated wiring systems in many industrial and commercial applications.



Nucor Tubular Product’s EMT is manufactured from high-quality, flat-rolled steel that is uniquely formulated for its high malleability. After forming and welding, the tubes receive a satin-smooth, corrosion-resistant zinc coating courtesy of Nucor Tubular Product’s exclusive electrogalvanizing process. Next, a passivation layer added to the product further strengthens its corrosion-resistance properties. UL-approved, water-based paint provides a final coating for circuit identification purposes.


Features and Benefits

Proprietary features – Easier wiring pulling and pushing: diamond-shaped I.D. pattern* and protective, slick inside coating (Silverslick®) reduce friction when pulling or pushing wires. The Silverslick® finish remains hard and smooth in various climate conditions, protecting your conduit and your investment. *Applies to ½", ¾" and 1" EMT sizes Easy to bend – Nucor Tubular Products’s EMT is made from an exclusive steel formula designed to provide high ductility and strength. Together with Nucor Tubular Products’s superior manufacturing process geared toward exacting internal standards, the product promotes wrinkle-free bends, reduced kinking, and minimized splitting from repeated bending and straightening. Color applications – Color conduit is rapidly becoming a normal part of building planning and construction. Commonly used colored conduit applications are: Red – Fire alarm Blue – Data communications Green – Health care purposes Yellow – High voltage Orange – Fiber optic Black – Architecture White – Architecture   System grounding and electromagnetic interference shielding – Nucor Tubular Products’s Color EMT not only protects people from harmful effects of faulty wiring, but also shields any nearby electrical and electronic equipment from damage by the electromagnetic fields. Nucor Tubular Products (NTP) products are manufactured in the U.S. from domestically sourced raw materials.
