If you’re anything like me you keep your van a little too well stocked (some many call it a little messy). As I was collecting steel conduit I wanted to check how much a few bundles would weigh to make sure I wasn’t in danger of overloading the van. However, I couldn’t find any easily accessible info. This is where this page will hopefully help!
I conducted some research then I put together these easy to read tables so that any electrician can easily see how much different amounts of steel conduit weigh. I’ve even included some accessory weights at the bottom to help if anyone is trying to do some calculations of overall weight for their install. Enjoy!
The different brands of steel conduit have differing weights so I’ve collected data from a few of the most popular. I’ve also done the multiplication sums to save people even more time.
If you came to this article looking for PVC conduit weights, you can find that article linked here.
The table below compares the most common brands of 20mm and 25mm steel conduit weights rounded to 2 decimal places. All these conduits are hot dipped to class 4 specifications (a great explanation of what hot dipped means can be found here).
Table of 20mm and 25mm Round Steel Conduit Weights
|Weight per Length (Kg)
|Weight per 5 Lengths (Kg)
|Weight per 10 Lengths (Kg)
From the table above we can calculate that:
- The average weight of a 3m length of 20mm diameter steel conduit conduit is 1.37Kg
- The average weight of a 3.75m length of 20mm diameter steel conduit is 1.68Kg
- The average weight of a 3m length of 25mm diameter steel conduit is 1.83Kg
- The average weight of a 3.75m length of 25mm diameter steel conduit is 2.14Kg
We can see from the data that there is a surprising weight difference between the Tamlex brand and the deta brand (I’ve double checked the weights listed on their sites and also provided the links so people can check for themselves if they wish)
If weight is an important consideration it may be worth choosing the more expensive Tamlex brand which is a lot lighter.
Steel Conduit Saddle Weights
I thought it would be beneficial to produce a table demonstrating the weight of saddles needed to attach the conduit to a wall or ceiling.
Table comparing steel conduit saddle weight
|Weight per Saddle
|Weight per 5 Saddles
|Weights per 10 Saddles
|Weight per 20 Saddles
- The average weight of a 20mm steel saddle for attaching conduit to the wall or ceiling is 17 grams
- The average weight of a 25mm steel saddle for attaching conduit to the wall or ceiling is 33 grams
We can see that over a long run the weight of the steel saddles can add up so it’s worth remembering to add them to our calculations.
Finally if we are putting up lots of conduit then chances are we are going to need couplers to join them together. I shall finish this article with a table calculating the weights for different numbers of steel couplers.
Weight Chart for 20mm and 25mm Steel Couplers for Conduit
It proved to be surprisingly difficult to get the weight specification of a coupler from any of the manufacturers, but I didn’t let that stop me! This is a photo of me using my kitchen scales to weigh couplers myself, all in the name of science!
This table below compares the weights of 20mm and 25mm straight couplers for steel conduit which are commonly used when joining lengths together.
Table comparing steel conduit coupler weights
|Weight per Coupler
|Weight per 5 Couplers
|Weights per 10 Couplers
|Weight per 20 Couplers
- The average weight of a 20mm steel coupler used in electrical conduit is 24g
- The average weight of a 25mm steel coupler used in electrical conduit is 36g
I hope these tables will be useful to anyone completing a steel conduit install.
Please bear in mind that these tables are meant to be a handy guide, if your install relies on exact measurements please consult the individual manufacturer’s specs as each brand will be different and the weights are liable to change over time.
