Green and Sustainable EMT contains recycled steel content of various amounts, depending on the steel manufacturing process, and will provide decades of reliable service if properly maintained. Conductors may be easily removed and new conductors or cables inserted. Future circuits may be added in the same conduit, as permitted by the code. At the end of its life, the steel may be fully recycled. |
|
Tested and Certified for Safety The Electrical Metallic Tubing (EMT) is CSA Certified to CSA C22.2 No. 83.1-07 (available on special order only) or UL® Listed to UL 797, depending on the market being supplied. It is manufactured in accordance with ANSI® C80.3, UL 797 and federal specifications WW-C-563. It provides mechanical protection for cables and conductors, reduces electromagnetic field exposure, shields against electromagnetic interference and is recognized as an equipment grounding conductor by NFPA 70: NEC 250.118 (4). |
|
Designed for Quality and Efficiency Steel Electrical Metallic Tubing is manufactured from mild steel strip in state-of-the-art ERW mills with the industry′s leading in-line galvanizing process that applies molten zinc to the outside diameter. A clear coating is then applied to the outside diameter to inhibit rust and reduce storage stains. The inside diameter is sprayed with a proprietary coating for corrosion resistance and easy wire pulling. Product is then inspected visually and with instruments to ensure all meet the product standard specifications. The complete in-house production capabilities and quality control programs provide consistency in production. |
