ALEX® Electrical Metallic Tubing (EMT) offers superior protection and routing for electrical wiring in various construction environments. Crafted from soft-raw material, and we are very proud that we are the only factory in China that uses this material to ensure our EMT is bendable while not broken, our EMT is available in pre-galvanized and hot dip galvanized options, ensuring exceptional durability and corrosion resistance.

Bending from the top is the most straightforward way to demonstrate the quality of EMT conduit, as it requires both high-grade raw materials and skilled manufacturing. Our EMT conduit performs reliably in this test, from sizes ranging from 1/2 inch to 1 inch.
Pre-Galvanized EMT Conduit:
Coating Thickness: Typically up to 20 microns with 275g/m^2 zinc coating.
Process: Involves galvanizing the steel coil before forming the conduit, resulting in a thinner zinc layer.
Application: Suitable for indoor environments where exposure to corrosive elements is minimal.
Hot-Dip Galvanized EMT Conduit:
Coating Thickness: Generally 45 microns, depending on factors like steel composition and immersion time.
Process: The formed conduit is immersed in molten zinc, producing a thicker, more robust coating.
Application: Ideal for outdoor or harsh environments due to its enhanced corrosion resistance.

How to calculate the weight for EMT conduit?
To calculate the weight of a steel conduit, you can use the following formula :
This formula accounts for the cross-sectional area and the density of steel, giving you the weight per conduit.
Example: For a 3/4" EMT Conduit, the standard OD is 23.4 mm, wall thickness is 1.25 mm, and length is 3.05 m. Weight = (23.4 – 1.25) × 1.25 × 0.02466 × 3.05 ≈ 1.36 kg
This is the standard weight for EMT conduit. For hot-dip galvanized conduit, the weight will be slightly higher because of the added zinc coating.
Zinc Thickness Testing for ALEX Hot Dip Galvanized EMT Conduit, as you can see 45.5um
We manufacture a large volume of EMT Conduit every year, and each bundle is wrapped in a blue woven bag for protection. This ensures that when you receive it, the conduit remains clean and well protected
Thickness Measuring for 3/4" EMT, Thickness Testing 1.26MM STANDARD THICK
Every ALEX® EMT Conduit is carefully deburred and smoothened on both the inside and outside ends to ensure wires can pass through without damage.
We normally use small woven bags for EMT conduit, since this is convenience for our customer to bring it out when it arrives.
