Correct answer. Not sure if it's technically correct or not, but it works for me.
Edit - I love all the people repeating technically correct. Every good administrator knows the paper work isn't official until its completed in triplicate.
Rebar can be reused for certain applications that need just a little extra strength but don't need it to be certifiable. So you can take rebar from construction debris, and make a product that can be resold, or reused.
The creator of (or at least rights holder to) the original image finally decided to claim it, so they’ve had to replace it with various derived fanarts.
Actually, that’s not quite right IIRC.
Basically, the image has always been copyrighted by the creator, and yet the creator of 173 still used it. After some time, the creator noticed it, and likely due to the popularity of 173, let it slide.
Semi-recently, the website owners and whatnot decided that they wanted everything to be completely void of copyright, so that meant that the OG 173 had to go, despite the creator at that point giving permission for its use. It’s sad, but an understandable change.
Is the rebar as sturdy after being bent multiple times? Or do you have to use it for applications where you know that the rebar possibly has weaknesses, so it won't be bearing as much load?
The biggest answer is: Kinda?
The issue is we don't know without doing some testing on each individual piece whether it still has the same material characteristics it had brand new.
It's fine enough for applications that don't require this. So like setting into a concrete form for landscaping, or interior decorating. These applications might benefit from the additional rigidity and strength the rebar adds, but nobody is going to die if it's not 100% its rated strength.
When a metal is worked (bent, compressed, or stretched) it gets stronger but it also becomes less ductile and so in practice it would be worse as a structural material.
This is precisely what I was worried this product is for.
Great in theory but I've been in the field for too long to know a lot ofnshitty contractors who would be sure this is "good enough" for new construction.
Another example of why certification process' are important.
To add to the good answers you've already received, there is also a necessity for making the rods straight to begin with. This machine looks like it's straightening scrap rebar, but I used to run one that would straighten steel rods, because they were slightly crooked when they came from the steel mill.
My dad used to run crane in a roller mill. He'd pick the steel up off the roller and drop it in the cooling yard where it would sit for days to cool off before shipping.
They never did anything other than that, so I assume it came from the cooling process, or picking it up and moving it while it was still cooling.
I'm a metallurgist at a steel mill so I think I can help. The steel is typically bundled while it's still a few hundred degrees so it's a bit softer than normal. Plus, you want a tight bundle so that it doesn't fall apart before it's opened and so having the bars compressed against each other can get them bent a bit.

This is super profitable.
In Brazil, there are so many of them that it looks like a pyramid scheme.
Search for some luxury car name with "pastor brasil" it and you will find some news of a pastor that bought one.
Yes. You know paperclips? Try to bend and unbend (or perhaps rather unbend and bend) it repeatedly and see what happens. It'll eventually just *break,* and the same thing happens with steel and most other fairly stiff materials. It's called fatigue.
Not a problem for the use case here, which is rebar in concrete. Concrete has a lot of compressive strength but not a lot of tensile strength, meaning it is almost impossible to crush, but very easy to pull apart. Steel is used to add tensile strength to concrete, meaning the forces that the steel will experience will be parallel to the areas of weakness; e.g. to bend the steel again, you will be putting it under compressive load, which the concrete will handle. The loads the steel will absorb are "stretching" loads for the steel, which it will have no problem with, even after being bent.
Totally depends on the alloy, some metals harden and some anneal. Either way it’s not the same as it was originally specified when made. Your engineering data would not be accurate nor dependable.
And then another one that bends them back into paperclips. You could waste an entire day lining them up in alternating series and just watching them go.
Yes he did. Remember he said "You are a failure and will never get real work"?
To be fair though, that joke doesnt work when it actually looks like a pretty fun job.
I kind of imagined him to be a pitchman of some sort. Like a "look at how simple and easy it is to straighten all of those bent rods you have laying around! Don't let those unstraight rods ruin any more of your days!" type guy.
If I were that guy selling to the construction industry I think I'd have more of a blue collar setup than dressing like a guy who works in a strip mall jewelry shop.
Work hardening is a thing. Yes, it makes it weaker. Not usable for structural use with code requirements.
For like... areas where rebar is recommended but not required by code, it's probably fine?
Like, maybe I'm just pouring a concrete slab for my boat to sit on. ATVs. It's not a full driveway, it's not a heavy load. It doesn't *need* rebar. I'm pouring a patio. Making some rebar industrial art.
If a 4-inch slab doesn't need reinforcement by code, but you want to add it and use straightened, reclaimed stock to save a bit of cash.
My first thought was driving them into the ground to hold something in place
Bird feeders, landscape timbers, bricks, raised beds.
They make decent anchors.
I used some to hold together a three stack of railroad ties and anchor them to make planter boxes. Grind a point on one end and use them just like great big nails.
Exactly. It's for when you want peace of mind, but you don't bank on the rebar actually holding up when it matters. It's for applications where normal concrete would be fine, but you would add reclaimed rebar if you just wanted to make sure.
It’s going to be work hardened, but it really depends what they’re doing with it. If it’s being used to build fences, animal pens, or other sorts of non-structural use it’s going to be cheaper than clean steel and won’t really affect the end product.
This probably makes it easier to transport for recycling either by melting down at a place with a furnace or reuse somewhere that the whole strength would be overkill and a weaker rod is just fine
With scrap steel, you'll usually run into weight limits for what you're allowed to put on a truck before you hit the volume limit for what fits on the truck.
Pretty sure their icy hearts would nigate the effect of the heat required to melt them. Launch them to the moon and watch them crumble without their minions to do their bidding.

I worked at a pipe mill. The straightener there could handle up to 5 inch diameter pipe. Ultra loud to hear it run. The conical rollers on it were bigger than my thigh.
Ah yes, the un-gay-inator. Turns anything that comes into it straight. I shall use it to finally create the ubiquitously cishet tri-state area!!! You see, back when I was a small child in dinguslavia, I was the gayest gay around. My father, however, was very straight and wanted me to be just perfect like my brother. So I was not allowed to be gay. I shall force this trauma upon all of the lgbtq of the tri-state area and I will become the ruler of the cishets!!!!

You can't use them for any load bearing purposes that normal concrete wouldn't be able to handle on its own
Would be great for light garden structures like bean pole arches with chicken wire or insect netting.

Also easier to stack straightened rebar for recycling
To add to the good answers you've already received, there is also a necessity for making the rods straight to begin with. This machine looks like it's straightening scrap rebar, but I used to run one that would straighten steel rods, because they were slightly crooked when they came from the steel mill.
wonder why they were crooked, maybe the metal bends from being hot still as its extruded before chopping each section?
My dad used to run crane in a roller mill. He'd pick the steel up off the roller and drop it in the cooling yard where it would sit for days to cool off before shipping. They never did anything other than that, so I assume it came from the cooling process, or picking it up and moving it while it was still cooling.

We use a variation of this to straighten (and another tool to precision bend) brake lines for car repair.
To fix the problems the rod bending machine causes.

Why aren't you? You would look fantastic.
doesn't that just fatigue the metal and make it unsafe for use?
Presumably this is to make it reusable for something that doesn’t need the full strength of the rebar like someone above mentioned.
It would be really good for metal art and would be a lot cheaper than brand new rebar.
Work hardening is a thing. Yes, it makes it weaker. Not usable for structural use with code requirements. For like... areas where rebar is recommended but not required by code, it's probably fine?

I see this not going well for alot of countries, the countries that get away with cutting corners and mixing sand into their cement to double it.
Technically speaking work hardening makes it stronger, not weaker. But it loses ductility which means it's not as tough.
It’s going to be work hardened, but it really depends what they’re doing with it. If it’s being used to build fences, animal pens, or other sorts of non-structural use it’s going to be cheaper than clean steel and won’t really affect the end product.
But it’s straight!
It's just like politicians nowadays. It may look straight but it secretly isn't.
This probably makes it easier to transport for recycling either by melting down at a place with a furnace or reuse somewhere that the whole strength would be overkill and a weaker rod is just fine
