EMT is thin-wall galvanized-steel electrical metallic tubing, unthreaded, per UL 797 / ANSI C80.3 (adopted in Colombia as NTC 105), for exposed raceway runs per NTC 2050 article 358. It spans 1/2" to 4" in 3.05 m lengths, joined with set-screw or compression fittings.
Galvanized EMT conduit is a lightweight-wall metal raceway used to protect and organize electrical conductors in exposed routes inside buildings, plants, technical rooms, warehouses and industrial panels. At TECTUL it is quoted as a complete 1/2" to 4" line with couplings, bends and connectors, according to the actual catalog data. Its value for the industrial buyer is the ability to assemble clean, serviceable routes compatible with commercial accessories without using heavy threaded conduit. It differs from IMC conduit because EMT is lighter and is normally installed with set-screw or compression fittings, while IMC is intermediate, threaded and used when the project requires greater robustness. It also differs from flexible conduit because EMT solves main rigid runs, not final connections with vibration. Selection must be coordinated with RETIE, NTC 2050, conductor fill, environment type, support and joining method approved by the electrical design.

Dimensions per ANSI C80.3 with UL 797 certification (NTC 105 in Colombia). Maximum conductor fill is 40 % of the internal area for 3 or more conductors, per NTC 2050 chapter 9.
It depends on diameter, accessories, quantities and delivery city. TECTUL quotes via WhatsApp based on the actual project list.
The actual catalog indicates EMT conduit from 1/2" to 4", with couplings, bends and connectors for industrial electrical raceways.
EMT is lighter and used in exposed routes with suitable fittings. IMC is more robust, threaded and selected for more demanding conditions.
It can be used only if the design, fittings, coatings and environmental conditions allow it. For demanding weather, IMC or another specified raceway is usually evaluated.
It is cut, deburred, fixed with supports, connected with compatible couplings or connectors and aligned before pulling conductors.
Couplings, bends and connectors are quoted. You can also send the drawing or list to review quantities by diameter.
No: EMT is thin-wall and joins with set-screw or compression fittings; if the project requires threaded joints, step up to IMC or rigid metal conduit.
Those occupying at most 40 % of the tube's internal area when 3 or more conductors share it, per NTC 2050 chapter 9; the calculation uses the area of each insulated conductor.
