There is high grade, epoxy coated, BHN rated for certain purposes.
Don't believe - bridge - the new bay bridge SFO/Oakland had to replace
some that were not to spec. They rusted. The Cement cracked apart.

Then there is the backyard slab of cement type. It contains sinks,
iron, steel - whatever is left in the kettle.

Maybe in the next weekend or two I'll make some mini tongs out of that
mini rebar. LOL.

The only thing that should be made with rebar is reinforced concrete.G
It's such a mystery metal that you have a very good chance of wasting
your time.

I've always found that a fascinating concept. Want your building's
foundation stronger? "Reinforce" it with some mystery metal which may
fail at any moment. I never got into any large concrete work, so I
never needed to know grades, but there are some. We mostly see the
cheap 40 rebar in building supply places. I mostly used it as stakes.
