rebar / all-thread vs.deformed ??
(OP)
I'm looking at a stack of rebar and the tag reads A615 grade-75 all-thread rebar. But in reading the definition of "deformations" in A615 I can't tell if these threads meet the given criteria. I think these are the bars usually used in tension piles. We're building a compression member. At any rate, are there any issues with substituting all-tread rebar for the normal A615 grade-60 deformed rebar?

Does the root diameter & perimeter meet or exceed the requirements?
If we consider a thread as a deformation, you would meet the maximum average spacing for deformations. However, does the thread height meet the minimum average height?
My gut feeling is that the thread bar should work.

Ask for documentation showing that the bar is equivalent.
It's not your job to show/determine that it's equivalent.

It appears that the justification for the substitution is convenience.
Also, it appears to be a Williams bar.

Typically, the deformation pattern varies by mill and size, and may vary from line to line in a single mill. Spiral threadbar is just another deformation pattern.
