I've seen alot of cages done out of seemed tubing. When bending put the seem to the inside of the bend,less likely to split.
Personaly I used DOM, a little more expensive, but I felt it was worth the cost. Rolled the car the third week out and not one tube was bent. That sold me on the DOM.

its all seamed.

Dom has a seam also its just less visible due to the construction process.

Hello Racer S, I suppose this,like so many other items of car construction, could be debated forever.....I think I'll pass on the never-ending debate, but I will offer you this.......

Most streetstock type cars are built from ERW seamed tube.......If you buy yours in a kit,it too,will likely be made of the same..........With thousands of these cars running every week, some guys just don't want the extra expense of DOM....

Safety then, is a matter of degrees.....So what is OK to You?

I don't think lumping DOM in with ERW as "seamed tubing " is a very fair comparison.......There is more to it than just the seam.....The ERW will most likely be made of 1010.....The DOM will be made of 1020.

A difference of about 20,000 psi of strength. The DOM will be of uniform thickness throughout.......the ERW will not.

Should you ever find yourself flying through the air inverted,about to land on your top, with only your safety equipment standing between you and the pearly gates, your safety equipment had best be up to the task......

Are you sure you want to give up the 20,000 psi??

I know, that wouldn't happen to You. But,being a lousy driver, it happens frequently to's the only way to fly......

Good Luck,
