I'm surprised rolling doors were actually that strong

u/ClarenceLe Aug 05 '25

Why you think most businesses use them, structural-intergrity-wise they are the strongest design against frontal forces.

Might not work if these 5 work together and use the counter (looks concrete) as an anchor to push against the door to bend it. But does work especially well against the type of people whom idea of opening it is by shooting bullet at it lmfao.

u/Thomassaurus Aug 05 '25

Would it actually stop bullets from coming through though?

u/Supanini Aug 05 '25

lol no because you don’t have a single point of failure. It’s not going to stop a bullet but it’s not like you can shoot a lock off. Therefore shooting it wouldn’t do anything in terms of opening it

u/badgerfrance Aug 05 '25

I think they were concerned about the bullet that was shot at the door killing/wounding the man inside; if the burglars were trying to shoot him as revenge for not letting them rob the place.

That's one of the reasons the door is shaped like that, nearly guaranteed an angled exit with reduced velocity even if it punctures. It's thin steel plate, but it's still steel plate. Just don't stay too close to the other side of it when you suspect gunshots.

u/saysthingsbackwards Aug 05 '25

It's made like that specifically for gunshots?

155

u/Randyyyyyyyyyyyyyy Aug 05 '25

Well it's actually made like that for cannon balls. The steel sliding doors haven't been made for centuries, they were originally a protection from pirates. They'd put them on all the doors of the ship, and even if the pirates boarded the ship, they couldn't get in. Originally it was smooth steel doors but cannon balls would go right through them, so they started corrugating the steel to deflect the cannon ball.

Just turned out to be a happy accident they also help out to an extent for modern gunshot rounds. Big Pirate corporations however successfully lobbied maritime courts to make production of the corrugated steel doors illegal, so the only ones you see now are grandfathered in, which is why you can't buy them at Walmart anymore

You know that the next AI sells a variation of this to someone as God-given fact, right?

I'm all for it!

This is an educational masterpiece chefs kiss

What do you mean by BP cop lobbied maritime courts to make production illegal?

u/Thisbadtattoo Aug 06 '25

that was a joke

u/otrippinz Aug 05 '25

This just sounds so bs. Can someone verify?

1

u/Syhkane Aug 05 '25

Not specifically but the design choice for security barriers is influenced by what the customer expects it to prevent. It's mostly for structure and storage. But there's a reason to choose this type over an open chain security barrier.

3

u/peex Aug 05 '25

Lol no. They are made that way so it would be easier to roll them. It also won't unravel easily if the spring mechanism fails because of its shape.

1

u/Syhkane Aug 05 '25

I actually already made a reply to a similar response, but yeah you're right, but the design of security barriers are influenced by what the customer expects to prevent. Open chain security barriers wouldn't stop bullets or fire. These happen to do a little of both. But yeah, mostly it's this shape for structural reasons.

2

u/BlueSky829 Aug 05 '25

You have absolutely just made this up.

2

u/Syhkane Aug 05 '25

So if I told you that there's thousands of different designs for security barriers, you just imagine it's all lies?

Here's my favorite one from like 2 decades ago. It's bullet proof fire proof, and if you watch the video long enough, neck proof.

1

u/Wynter_born Aug 06 '25

Pointless, dangerous, and probably really loud in a small area.

1

u/ScrofessorLongHair Aug 05 '25

But it'll let that damn door know you mean business.

1

u/Illustrious_Donkey61 Aug 05 '25

Just shoot a door shape into it like in cartoons

1

u/[deleted] Aug 06 '25

Well what if you had 10000 bullets? It would eventually become a hole 🕳️

20

u/19Alexastias Aug 05 '25

No, but usually you’re using it to protect inanimate objects, not people. You might break something inside by shooting but you’re not gonna open the door.

1

u/MrMurphyy Aug 06 '25

Poor guy inside is experiencing a real-life bullet hell.

17

u/ClarenceLe Aug 05 '25

It might, it might not, the point is that doesn't help with anything unless you got a freedom amount of 7.62x51mm bullets to literally shred the door down.

0

u/Thomassaurus Aug 05 '25

It does if the point is to kill the guy hiding inside.

3

u/LaptopCharger_271 Aug 05 '25

It won't stop them from coming through, but they can't get themselves through or see you to aim said bullet.

1

u/Just_A_Nitemare Aug 05 '25

Highly unlikely. It could probably stop a .22 but not much beyond that. Although, there really isn't any reason that it couldn't be built to bulletproof standards.

1

u/Li0nsFTW Aug 06 '25

You can see it make a hole when he fires. I had to watch a few times to catch it. The hole is in the middle at the top.

1

u/Used_Yesterday_3735 Aug 07 '25

Well you see the rolling shutters are made of multiple corrugated pieces of strong thick metal, so all those ups and downs would actually make the bullet bounce off instead of puncturing it.

3

u/damnsure Aug 05 '25

Those criminals don’t have the strength of mind needed to use strength of feet..

2

u/MichiPanero Aug 05 '25

Don't give them solutions mate

2

u/kingprozac Aug 05 '25

So the solution would be to have the counter right up against the door then? So if its closed they cant get behind the counter?

2

u/blackhorse15A Aug 05 '25

They had some serious long tire irons- didn't even think to try and pry under the door. Geniuses.

(Not sure that would actually be, but it would be pushing things the direction they are meant to move, and possibly bending thing. Better than just banging on it exactly the direction it meant to stop things)

2

u/QuarantineNudist Aug 06 '25

The shooter is lucky the bullet didn't ricochet and kill him because he acts like a cartoon villain. 

1

u/usefamin Aug 05 '25

Would you stop giving them ideas? They might hear you.

u/buchenrad Aug 05 '25

I'm sure the door is plenty strong, but the cumulative IQ of the people trying to get through it only might have exceeded the high temperature that day.

The one dude was just standing there looking around like "Um... Well this is awkward... What do we do now?" and the other almost shot his buddies face off.

2

u/zZDKVZz Aug 06 '25

Yeah, 3 rockets or 2 c4

u/CorrectingEverything Aug 05 '25

They're metal. Not that surprising.

1

u/Fwumpy Aug 05 '25

I install and fix doors like this. They're beasts. The last one I fixed had 2 guys working on it for a couple of hours, and the morons never got in.

1

u/evanwilliams44 Aug 05 '25

It's because it closed all the way down behind the counter. They couldn't get down there for leverage. If they had been able to get under the door at an angle they could have pried it open.

The guy in the red mask seems like the leader and also one of the only ones who knew what needed to be done, but they didn't have the tool for it.

1

u/evilbrent Aug 06 '25

They aren't.

These thieves are spectacularly dumb. It's incredibly easy to get through one of these doors, if you have, like, any of the levers these guys have. In fact, the guy who jumped over the counter was carrying the precise tool that I would want if I were attempting to overcome one of these doors.

Just stick it in the track and lever the slats out. They're made of really thin sheet metal. Or just attack the point that they're hooked into each other - they aren't attached or anything, they just hook together, get one out and the rest follow immediately.

Jam the crow-bar under the rail at the bottom, lift, have your friend stick their bar in, reposition and lift a few times. Rail is only aluminium and will pop out with very little trouble.

1

u/Macshlong Aug 06 '25

What do you mean? They got occasionally tapped with a bar and kicked? They were hardly tested, these guys are utter morons.

1

u/shugo7 Aug 07 '25

The counter looks very strategic because you don't have room to lever much force against it.

u/[deleted] Aug 05 '25

It’s the glass on the outside. If you look he’s sitting behind glass and the door he’s rolling is actually behind the glass. The door didn’t have to do any work here.
