You don't really realize how absolutely massive these things are till they're down with you on ground level
Same thing with trees
Even the lights themselves are massive. The old school ones used to weight over 100lb
Ikr From the car window they look so thin
This was more interesting that I thought it would be. Never stopped to think what went into building one of these poles.
Me 2
I did tbh 😂
Go back about 50 years when "art deco" poles were used for traffic lights.
My addiction to How It's Made started many years ago with chainlink fence. I thought, "How could ever they make this interesting?" I vastly underestimated them.
The people who made the pole after putting "epic ave" on the sign

I want this man to read me a bedtime story
What does your therapist say about that?
@@Jimmyjimjimjim LOL🤣
😂😂😂
LmAO
Lmao 🙄🤦
with all the dye cast models you use in the beginning of the videos, it makes me want to see how dye casts are made now
They aren't made. Usualy found burried 100-300m. There is a mine in Utah thats been mining for them for the last 45 years
lmfao @@Go-off-yourself
They are also built to absorb the impact of a vehicle ramming into them while getting damaged and inflicting the least amount of impact to the car.
Huh, please explain that last part.
More Interesting than I thought it would be.
The shear size of everything used to make these is pretty wild honestly
Walked into one of these while being distracted by a pretty girl. I can confirm, these poles are strong.
Seeing the zinc crystalline patterns on these always hurts my teeth. I ran into one of these poles as a kid and chipped a tooth and now it hurts to look at them.
You are the main character in a rom com
Actually I bet the guy distracted you
Or you're weak
@@rubiconnn Random related side note: the pattern that galvanizing can create is called "spangle", and the size of the "plates" corresponds to the durability of the coating. IIRC
There’s a Great effort and dedication behind every small single thing…..,😊
That welder is awesome, It's called Submerged Arc Welding
the size of these components are... larger than I thought, when the workers stands beside them.
Best show to watch in free time, 🙂😉
During the time of the employer is better though
Watching this while trying to go to bed lol
That plasma cutter is about one million dollars. Just thought you should know
I was just thinking about how amazing these are yesterday, when we had 60 mph winds and I was sitting at a traffic light. Interesting that this popped up today.
Did you know? Brooks Turner Moore, the narrator of the US rendition of "How it's Made," gained notoriety as the primary suspect in the infamous "Wonderland Murders" of 1981. Though he is still considered the primary suspect of the gruesome murders he was never arrested or charged due to a lack of evidence. Thanks.
Wow. Amazing
Galvanizing is key!
True 🙂
Everything counts
Chrome plating the poles would be impressive.
I can't even tell you how many times I've galvanized those poles.
How good is the galvanic coating? Does it really last 40 yrs?
@@joeg464, depending on the mills applied/adhered yes and even longer. 40 years is a minimum expectancy.
For example. A light pole, piling, bolts or boat trailers that are exposed to the elements you can expect about that or even less.
For something that is not exposed to the elements you can expect to have 80 years +.
I don't want to think of how many miles of wire I burned welding these things up.
Not going to lie, little disappointed that they bent it into a dodecagon instead of an actual round pole, was expecting a "finishing" smooth to round it out.

Client preference. There's a design equation for minimum number of sides in relation to the flat-to-flat diameter. The design code also says round tubes of similar size have greater fatigue resistance than multi-sided. Ref: AASHTO 2015 LRFD Specifications for Structural Supports for Highway Signs, Luminaires & Traffic Signals, Section 5.6.2 and Commentary.
Haha me too! Not sure why
cost more.
@@reillythompson664 That's really neat.
Thanks for the explanation 👍
Just Wow!
very cool, and imagine how much zinc layers, must be on the chain lol
Falling into a giant tank if molten sink is a death fit for a super villain.
Well I never wondered how these were made but now I know I guess
okay, added to my list on "how i DONT want to die"
tripping and diving straight into molten zinc bath.
A 'multi-sided' round pole?
Multi-sided... round pole!
Think about that for a moment.
A circle is a polygon composed of infinite, infinitesimally small sides.
Cool!
This channel is very interesting!
Have you seen the however channel?
Probably no!
That is a lot of metal! i wonder how expensive this actually is
$5000 per pole
U won't believe this, but the other day I was thinking about how these were made :D
Now when I total my car into the pole I'll know exactly what it's made of and how it's made.
Fascinating.💚💚
the real heroes are the chains that holds the poles during the acid + galvanize bath
Epic Ave
And I still watched one fall over into the highway XD
Very interesting content so amazing channel I love it thank you great work
new friend here 🥰🙏
I never realized how thick the components were...
Imagine falling into the tank of molten zinc
No
Or sulfuric acid

Fascinating.....................................thank you
Last 40 years?!
I’ll be dead by then.
Well technically speaking, most galvanized poles are able to last for up to 70 years before the rust eats away at the steel. Where I live, we got some 50 year old street lighting poles and the only thing that's happened to them is light surface rusting. This is because the poles (including the one in this video) go through hot-dipped galvanizing processes. Also note that galvanizing doesn't have an impact on the tensile strength of steel.
Man I wanna go to *Epic ave*
I don't think I've ever had any curiosity about traffic signal pole fabrication. And now that I've seen this video, I've come to the conclusion that I'm very stoned and hungry.
I want one now.
God bless you all.❤
Damn they are made strong enough against drunk drivers too.
This is sick
Man that mini version they had I wish they would sell it
They do
This channel still uploading
How behind the scenes made 😂
shows round poles then explains how to make octagonal poles. i wanna see how they make the round ones. i’ve never seen a multi sided traffic pole before i’m my life. they’re always round.
it is the same process, just more bends on the press break using a different die on the ram and a wider set to the base and not as deep of a bend.
They form them around a mandrel.
I'm guessing you need a highly skilled welder. Looks like it would fall over if not done right.
epic ave
These poles also to crumple so they can absorb impacts from accidents.
Epic lane
Welding is used in more than 80% of manufacturing processes.
Usually by robots
Wish they galvanized truck and car frames the same way. Sucks to see them rot out after a decade or 2 of winter n salt on the roads
Wow even tho the machine wields the pole together I know the workers get paid a lot of money
They top out at about 22/hr at my work. Its a pain in the ass of a machine to run. Much more difficult to run than the brake or the plasma. Brakes have a huge learning curve, but not in this line of work, specifically.
Apparently it can withstand high winds and snowfall... if you watch any hurricane documentary it'll tell a different story of their strength... like Uri Gella and spoons 🤣🤣
When will SC How It's Made film an episode on money, so I can learn to make my own! 😀
How comes its not a circle but a hexagon? I’ve only seen circle ones?
When someone tboned me, my srx sideswiped a signal pole just like the one in the video at 55-60 mph... wrapped around it then bounced off. luckily Cadillac is a leader in safety but my point is, these poles can withstand ANYTHING.
the only minor damage done to the pole was to the crosswalk button, which was knocked off the pole but.. still hanging on by the wire. And again, this was a large heavy crossover suv that got hit by another car right into the pole direct impact. did nothing to it. id say it helped save my life, too.
Why can't they make galvanized cars to last 40 years or more?
because steel is heavy, and expensive, galvanizing is even MORE expensive, resulting in a car that costs more, and uses more gas, causing it to be more expensive to run.
and if it catches fire results in everything nearby dying, including the fire fighters who come to rescue the person in the car.
also difference circumstances, a TRAFFIC LIGHT, a low stress, and stationary life kept more protected from salt than say, the bottom of your car which constantly gets salt, and rocks, and other road detritus kicked into it, zinc is soft it scratches easy, wearing off the protective coating, it deteriorates faster in the presence of salt and excessive moisture, and the moment you get one weak spot, it spreads. all of these combined lead to galvanized metal being a terrible choice for basically anywhere in a car.
Cars began using galvanized steel in the 1980s. Different manufacturers at different times. Cars used to rust a lot quicker before that.
It is difficult to paint galvanized steel, the paint just doesn’t stick. So they had to figure out how to paint it before they could use it for the body panels. I believe they did this by electrostatically charging the paint and panels so they were attracted to each other.
Galvanizing doesn’t last forever but it does last a lot longer than non galvanized steel.
Modern cars are designed to be weak in certain spots because it's safer in a crash. If you hit a brick wall but your car hasn't dented, then you're probably dead because your internal organs got the entire impact.
Porsche 944s are galvanized. The reason they don’t galvanize cars is twofold. 1. Galvanized steel is harder to paint. 2. Galvanized steel lasts a lot longer and the auto industry is notorious for planned obsolescence.
Rubber covered at the bottom for snow accumulation,plus salt 🧂 👌
Plus those straps they got to go.

Aren't you a Karen of utility poles.
But how do they make "How it's made" videos?
Does anyone know why they Don’t use a hot rolled hollow structural section HSS for light poles?
It is not anywhere near strong enough to be able to support the weights and withstand the wind and impacts that are called for in the specs for these signal poles.
40 years doesn't sound long at all
The ram on that brake has seen some way better days
High strength in today’s age lol
I guess they're not strong enough to hold up when I crashed into one
I had no idea sign posts were dipped in T-1000s
oh, so giant vats of acid exist in real life as well, not just cartoons
I want to live on epic ave
You know your a welder when you have to make remarks on the welds to yourself while watching hahaha spectacular welds btw 😅
Why don’t yal come out on the job when they are getting installed it more fun my company out of hot spring Arkansas. We do a lot of them a year
Hallo!
Only to be smashed by CJ!😂
#GTASA
I only just realized I never knew what traffic signal poles were made of XD
Only the ones in 'merica
Forgot the occasional drunk driver
Sooo,,,,, why don't they just use Steel Pipe? This seems like a very time consuming and extremely expensive way to make a pole....
Adding bends increases the pole's rigidity. Long round steel pipe would bend like a noodle.
You owe a debt of gratitude to every DUI driver for keeping your workers from losing their jobs. Think about it.
Very cool to watch this in the meantime.
Warped
I can just easily destroy it with a one small crash with my car in GTA
The music on this video was annoying. It was over the speaking voice.
It is not galvanization, it is the same coating but using melting metals instead of galvanization.
... uh yeah, it's hot-dip galvanization.
@@ssl3546 Totally misleading phrase. Why the Us people love to use the same word for everything, and another word for everything too, and how one can talk like that.
Normally, you should have same word for same things and different words for different things.
The word is coming from name Galvani connected to electrolizing things. Nothing to do with molten metals. How stupid.
They are overbuilt. So massive pols can stop Russian thank but I don't see a need for it.

“Hmm, interesting”
The very first comment ever posted on TH-cam was "Interesting".
Gta wants to have a talk with you
I am druckl as fluck wtching youtube again
Wwwooooooooooowwwwwwww
I really hate traffic signals especially new ones
What is so different about them?
They're LED based?
If only better engineering went into the flow of traffic in particular intersections where traffic didn’t build up, and more vehicles passed through.
I agree, but It's an extremely complex science beyond me lol.
Having this metal alot like everywhere have road, how much is it actually? Just curious, because definitely cheap right? What kind of buying is allowed for this metal?
I can't understand your question :(
