EMT conduits, or Electrical Metallic Tubing, are lightweight, thin-walled metal conduits used to protect and route electrical wiring in residential, commercial, and industrial applications. Known for their ease of installation and clean appearance, EMT is a preferred choice where mechanical protection and cost-efficiency are key.

Key Features
• Material: Typically made from galvanized steel or aluminium for corrosion resistance and durability.
• Lightweight & Rigid: Thinner walls than rigid metal conduit (RMC), making EMT easier to handle and install.
• Smooth Interior: Facilitates easy wire pulling and minimizes cable damage.
• Corrosion-Resistant Coating: Ideal for indoor and dry locations; with added coatings, it can be suitable for damp or mildly corrosive environments.
• Versatile Sizes: Commonly available in sizes from 1/2 inch to 4 inches in diameter.
