SK so not much help there.

I can offer some information, but not much specific.

I usually purchase a fait amount of 6061-T6 in 1.5 and 2" with various wall thicknesses and it comes with color coding paint on thr ends.

Steel Tubing "usually" doesn't have a welded seam, while pipe "usually does. Structural steel tubing has a seam and comes in both schedule 40 and 80, like pipe.

If you find steel that is relatively smooth and no sean and standard wall thicknesses like 1/8, 3/16, or 1/4, it's probably DOM or Drawn Over Mandrel.

About the only way I know of to figure strength is "I believe, a durometer test for hardness


Sorry I can't be more specific, but there should be members far more knowledgeable than I on here and maybe one of them will step forward.

73 and good luck,

Roger (K8RI)

Thanks in advance.
