Hey guys I'm building a girder. Went looking at 1" DOM tubing. Anyway they asked if I wanted 1020 or 1026. He lost me there. Still learning. Price difference very little. Which would you recommend.

From what I can tell 1026 is a step above 1020.

I've read in one place .120 and another place said .134.

Bet if I looked some more I would find a different thickness.

Any recommendations please.

Thanks guys.

I ask an engineer at work and he says to me that the 1026 would be 26% carbon and would stand up better in to vibration cuz it wouldn't get as brittle during welding.

1020 being 20% carbon

1026 DOM it is.

Now to the thickness issue.

Then we can order tubing.

Thanks

I dont know what over kill would be but not less then .125 would be my guess and its just that, a guess. I think some math may be involved. You are making a triangle and that should be very strong.
