also hard to say with any certainty but the drone photos don’t appear to have quite the same degree of tie-down gear as drivers look for in a “suicide coil”?

Has anybody seen an update on the mill that was making these for SpaceX and the CT. If I recall it was 100 miles south of Austin or so, kind of splitting the distance logistically.

The beginning of this thread was a question as to whether these rolls are stainless steel. I have not seen that question answered. I also haven't seen my follow on question answered, namely is the height of these rolls sufficient to fold the CT exoskeleton? I suspect not. Before everyone goes off on the manufacturing process maybe we should try to answer those questions.
I thought we all agreed that it probably isn’t. Certainly nothing about it is conclusive

Threads just crossed !

Watch the Jay Leno video and in the background are multiple rolls of stainless steel!

Yeah, they're not making stainless to the quality that SpaceX is using, so they're not the supplier.

Yea, and the next day,, Joe provided a good lit view on the inside of the south stamping area , which had a lot of earthworks still going, and to me looks like the large foundation and whatever goes on top is months away.

That video doesn't cover all of the space, but just on that, doesn't look ready for SS rolls.

if you thought the intent of your post would be clear absent annotation, you were mistaken:LOL:

I’ve seen there are some straps. I’ve seen there’s also a guy up there, so possibly straps have been removed already - at least for the one he’s standing near.

but I’ve also seen, e.g.,

They didn't use chains like that for the SpaceX rolls. Not alot of big mountains between Alabama and Austin or Boca Chica.

Mountains? I think the issue instead is breaking whatsoever.

But, if it’s the steel and you say prior trucks weren’t strapped that way, then perhaps it’s steel that’s just not that very heavy!

Standard trailer having a ~48k lb limit by law, puts those two coils at a ceiling weight of ~24k per, and:

Don't use to much common sense. You get shunned here for that lol. ;)

Do I really have to measure the picture to work out the specific density of the roll to prove to everyone it’s not stainless steel rolls? Just take my word for it.. its easier. 🤣

googling to find picture of the Space-X rolls on truck mentioned by @Crissa (I didn’t find any), I instead came across the Space-X version of this forum …

and I thought you lot were a bunch of nerds!

I’ve seen elsewhere (not bothering to look it up at moment) from companies that do steel casting modeling that the precise issue is that the steel is too strong (not “hard”) to bend without causing the steel itself to fail/weaken - something like, that the cold-roll strengthening process causes the material’s strength to approach its tensile limits, and so, as it becomes harder to bend, it simultaneously also becomes less likely to bend rather than deform/break.

folks saying “it can’t be bent” I think are fairly interpreted as saying “it can’t be bent and still function appropriately”
Would also like to add that Tesla has created their own blend of SS that most likely incorporates properties that overcome the tradition forming challenges of “legacy”, standard SS that is being referenced. I believe (just my opinion) that they created their proprietary blend of SS to be the forming solution that will overcome the common failures within the forming process.

again not looking it up at present, but the information I referenced above was from a source that basically described how what your are hypothesizing is not possible at some basic level of materials science - the person described it well enough that I could follow while reading, but not that I can here recount the specifics

but my (rough) take-away being as follows: the SS being a “30x” brand of SS (eg, akin to a 304 but with some secret sauce making for the substituting “X”) requires the SS to have certain qualities that mean that “strengthening” it to the levels indicated by EM (eg inferred their specific bullet-proof was claims, etc.) essentially requires that it become at some proportion less mailable (absent failures/weak-points).

and in any event, isn’t it EM himself that psuggested this was exactly the case: he said they truck had to be so angular precisely because they couldn’t bend the SS

then again, who knows what to believe since EM said it would break presses which this same article described as being wildly incorrect/impossible *shrug*

Whats the forums name? I don't like being insulted like that. Will need to sort that out. 🤣
