    from what I understand the DOM isnt any heavier, it has something to do with the carbon content of the steel.

    DOM has no seams, HREW does. DOM dents, HREW bends.

    DOM is typically used in race cages do the to fact that it doesn't have a specific point for the tube to fail (compared to HREW that will fail on the seam that it was welded)


    I went with the DOM sliders. You're welding them on so they're basically going to be permanent, and the price difference really isn't much at all, so might as well go with the stronger material.

    I totaly understand. (I was 99% sure on getting the DOM anyways) I was just curious how much of a difference it made.
    no idea

    DOM stands for Drawn over Mandrel. One solid tube with uniform thickness.

    HREW stands for Hot Rolled (Electric Weld?). Basically a flat sheet that was made into a circle and welded, so the thickness isn't always going to be uniform.

    that explains it better than the articles I was reading. DOM sounds like the way to go for sure

    Actually DOM DOES have a seam...DOM starts its life just like HREW, but it has an extra step, which is where it is Drawn Over a Mandrel (DOM). This basically cold works the steel and make the crystal structure stronger where it had been weakened from the weld (difference between DOM and HREW). It also helps maintain much tighter tolerances over HREW (not something you really care about for sliders). At the end of the day, if it is only a $50 difference, then go with DOM.....for that much tubing, it would usually be about twice the price for materials, so that is a good deal. Mine are HREW and work just fine for me (however, if I could have gone DOM for $50 more, I would).

    For the extra $50, get the DOM, I wish that I did. Mine haven't bent, but since they are welded on, I should have gotten the extra insurance.
