I've been doing this for the last year and even though I've already seen a couple big explosions due to missing vent holes, this whole process is fun to me. It's like an art making the steel look as good as possible. I always joke with my manager "Hey how much more is chrome than galvanizing? Our customer might not pay for this if chroming is more costly". I can suggest as well, maybe bringing the racks up a little slower.. It gives more time for the zinc to run and you won't have heavy lips or nearly as many drips in the end. Love seeing other shops setups.
Chrome plating is inferior to galv for corrosion protection, even though it looks pretty. As soon as any water and oxygen gets underneath, the chrome bubbles because it's only a barrier. Galv protects steel electrochemically and alloys at the surface so it won't peel off.
1. The crane has wires, but the heat dont demage the wires. 2. The brown stuff is ash, from the ammonium-zinc chloride, that burns in contact with the zinc.

I work at a Valmont galvanizing plant in Alabama and it's not uncommon to see a pole or product fall off the wire into the kettle or chemical bath tanks. We have an extraction process using long chains that generally takes 10-20 minutes whenever that does happen. I've never seen anyone get hurt from it.
Question, are zinc fumes created in the process? I work in a galvanizing facility and was wondering if breathing protection should be used around the pot.
I dip the products at a Valmont kettle and it all depends on which side of the kettle the smoke is blowing. The smoke at my kettle rises straight up, but breathing in a shit ton of it at one time might hurt you. Other than that it's not that bad. Just let the product cook off and by the time the sweepers walk out to sweep the ash back most of the smoke is already gone

Hi, Looking help from experienced people in Hot galvanise We have started Hot Galvanise process in San Luis Potosi, Mexico and are having many troubles in getting the perfect final product. sometimes either zinc is getting burnt or sometimes the finishing is not coming properly. We know that we are missing many things to make it work. Is any there anyone who could help us with this? Help will be much appreciated!

What is the one thing keeping the entire industry from switching to Zn-Mg-Al ternary baths? The galvanic protection offered by those are up to a few hundred times greater than normal hot dip Zn.
The first step is to submerge the iron parts into the molten zinc, what is the temperature of the hot zinc? The second step is to put the galvanized parts into the cold water? Is it to just cool down?
I just got hired at the galvanizing facility here in Washington. Saw then most the material to be lowered into the kiln and then the tour proceeded 😐😐 Cool to see what I missed in person. Can't wait to get my hands dirty in the business.
They're removing the excessive zinc which forms on bottom edges of the hanged elements. It's much easier to do it while it's still hot and fresh out of the dip, than afterwards when it solidifies (might rupture the coating around it when trying to remove it).
Yes indeed, companies do that, they do hot dip galvanization to give best results and corrosion protection to vehicle chasis. It can protect your vehicle chasis from rust / corrosion for a long time.
Passivation tank, incidentally, this is the second kettle wherein the only space we can put it is after the passivation tank. Due to limited space thats why its there. ALthough a process with one step back.
In hot dip galvanising you dip the item to be galvanised into a flux tank before putting into the galvanising pot. That makes the zinc stick to the metal.
We send pipes for galvaniaztion in Cavite. Now the flange seration of the pipes was covered with galvanized. HOW TO REMOVE THE GALVANIZED ON THE SERATION?
It's weird the differences in how the process is done although the process yields the same result. The kettle I work on is its own structure and the cranes ride an oval rail setup. The top of the kettle closes the side doors close, the end doors close. Wish they were able to keep it recording for the actual dipping. The popping and exploding of cold steel against that hot zinc is pretty entertaining lol and for those wondering, the zinc is about 830-850°F.
this is the old design wherein there was no fume capboard then. We have to improvised the fume collector on a plant with horizontal design. its a plant 2003. But our totally new plant has vertical design and permanent fume capboard as you were saying.

Question to the experts! Whats happen when hit dip galvanize parts which are already hot dip galvanized?? 2nd Qestion. My client requesting to confirm min 100um HDG thickness. (100um min, doestn matter the sheet thickness). Is his request legit??
WHen you dip again a galvanized product, you either strip off the original coating until the bare steel appears or if you just dip it without strippinng off, it will be very rough. We discourage regalva because if it is stripped off, the acid fumes will be thick THe zinc coating thickness cannot just be dictated arbitrarily. The ASTM A-123 (2015) or any related BS?JS/ASNZ standards should be the guide for the zinc coating minimum thickness compliance. It will be impossible for a sheet to have 100u coating thickness. Use the International Standard in matter of min. zinc coating thickness compliance
No, car body parts are usually electro-galvanized or galvannealed (often stamped from such a processed sheet) and then covered in a phosphate conversion coating and paints. The entire process is water-based and allows entire assemblies to be dipped into tanks and get any complex geometries that a hot-dip process would struggle to deal with.
Thanks, few more info, please. 1. Do you add Nicket in Pure form, as the Melting point is high? If no then how you add Nickel & what is the Percentage of n=Nickel you Maintain in Liquid. 2. What is the Percentage of Aluminium in Liquid you maintain?
@@rajibchatterjee3031 nickel powder needs an injector to infuse it to the kettle but wtih downtime. Another option we use is Nickel alloy. The percentage of Ni. ideally at .055% and Alum. at .002%
may i know what type of material u use to remove the ash from the upper bath?the one which follow the galvanized item?aluminium?ss? or just normal mild steel?
How often do you folks have problems with stickers or paint being left on the steel? It isn't much of an issue with our plant, but sometimes I still grind off those leftovers. If you've got no issue at all, please indulge me lol
I grind off the stickers and lettering that doesn't come off in the acid when I inspect the product before I dip it in the kettle and it normally comes out fine. If I miss a spot we have a metalizer guy that dresses it before it's shipped
@Norm T ppe is not just safety shoes and reflective vest. I can think of something more here such as face shield, respirator, gloves and coverall. Most importantly, remember ppe is the last defence.
@@abdulwahabkhan4675 The zinc is at 834 degrees and when it's 100 degrees outside it's 120 inside. who wants to wear coveralls? When you do this job the motto is "learned to get burned"!!!!
In our 25yrs in the industry we never encountered such a problem, double checking during jigging is the key Second check of jigs are done after acid pickling and before galvanizing itself
This is just to show dipping en pullout of items for video Usually the fume/splatter capture board is enclosed.. so no workers are near the galvanizing tank during dipping
Does anyone know any forum of galvanizers? I have recently started working at such Plant but still face some problems while making a desicion at certain points. I need suggestion from an experienced people. I'm ready to share with my experience as well!
Watching them clear the slag off the molten zinc without respirators makes my skin crawl.. zinc oxide fumes are neuro-toxic.. poor guy probably gets the shakes every day.
Seriously. I've gotten metal fume fever a few times from zinc. I can't imagine breathing that shit in 40 hours a week for years on end. Those dust masks don't do anything at all for fumes. This company is reckless with employee safety.
i've been working with galvanizing for 4 years now, never used a mask when clearing the slag. some people have been there for 20-30 years and have no signs of zinc poisoning. you dont really get that much fumes coming up at you.
District of Baroda in Gujarat, India has the most galvanizing plants, 26 HDG Plants within a Radius of 30 kms, Bath Length ranging from 10 mtrs to 2 mtrs
I have some question regarding your processes. Do you hang the poles on the beam starting from pre treatment? If so, how do you transport the beams back to the start of the processes?
there are poles that can be hang on a jig but the bigger ones are jigged seperately and tied both ends because the beam jig is small. For bigger heavier ones, we use chain
At our plant (Valmont) we rig the product onto crane jigs with either wire or chains and from there it goes to a caustic bath, acid bath, flux bath, and then to the kettle. After the product is extracted from the kettle the jigs get placed on top of a transfer cart which transfer the product to the final inspection department dress/inspect the product. After the product is approved a "Combi-Lift" moves the product to shipping and receiving.
flange side would be more important to not have bumps or drips, who's gonna see a drip at the top of a 20 foot poll, but the guy installing those is gonna notice a his flange not sitting level, flip the angle
@@KeoN710 if they flipped it, the bottom of the flang would be a smoother finish, yes there will still be some build up and drips near the edges but on no critical surfaces, with a flip it can be can be cleaned up with a hammer, nothing to grind that way
@@KeoN710guy I've poured maple syrup on my pancakes once or twice, trust me, a flange doest help aunt jemima have less drips If it was flipped it would have a few drips on the top edge of the flange, but it would be much better then a large build up of zinc on the bottom mounting surface, this way it would need to be ground back to being flat.
Just as long as the process is not done in China. They do not do the quality of plating US companies do. The coating the Chinese use on the inside of galvanized pipe wears off quick, 2 years from domestic water and as well as inside when used outside for gas piping, the coating flakes and gets into gas regulators, gas valves, orfices etc. The Chinese pipe is usually sold at box stores.
@TheSushiraw than why so many other countries copy our engineering? Lol. Lol. Lol. Lol. Lol. Lol. Lp Lol. China sure does not engineer ANYTHING. LOL LOL. If you call copying something engineering?
if am not wrong in hot dip galvanizing process the entire metal has to dip in one go not like up and down coz It might get crumble on the long type metals due to hot dip in one side and cold on the other side
It depends on the part. Some parts like handrails you have to stop occasionally while going down with them otherwise air builds up too fast and they float. Then they REALLY look bad. But on the way up its much preferred to do it without stopping. Otherwise you get those horrid flaky lines across the parts.
We opened the fume en splatter board for video purposes only.. which slides during galvanizing Normally it is enclosed to avoid splattering workers.. no workers within 15mtrs of the galva tank during galva
Looks really cool, but it's such a "dirty" process. It's relatively easy to coat the outside, but coating the inside is typically the challenge. There are new methods available that are faster and cleaner than this - but they are not on the market yet!
At one of the valmont plants someone was in a kettle explosion that guy lost his leg and over 90% of his body was burned he survived but the only thing that saved him was his face shield
Yep, turn off the auto-focus and leave on Manual. Both shots were from about the same distance. And a little editing wouldn't hurt either. Watching that large cover creep over the tank was way too long. Still a cool video!
I wanted to see this as well. My brother told me this story he was told, where they'd drop the metal parts in quickly when they had visitors just because it was impressive.
Watching the video was good enough so long I did not find people coming so close to molten zinc tank and manually saperate or shake the beams apart. Sorry to mention, the Safety part of production is in questionable be it from a developing or developed country. We belong in such time zone when Mars and moon being explored, automation proccess is highly expected around these areas of production.
We opened the fume en splatter board for video purposes only.. which slides during galvanizing Normally it is enclosed to avoid splattering workers.. no workers within 15mtrs of the galva tank during galva
People gotta stop using auto focus. A camera just can’t know for sure what you’re trying to look at all the time. You twist that lens, you’re all good.
two possibilities, water or passivation. well due to the color of this water, it might be just polluted by steel or it might be a passivation wich is a chromic solution, so the zinc wont oxydize after that , or in time it s the chrome who oxydize before the zinc sorry for my english
@@philgalvindustrial9381 That's surprising. I would have thought with the heat and the application that you wouldn't want to paint the beam. It's galvanized after all.
All they have is and eye protection hood? Most of the commercial production of zinc involves the galvanizing of iron and the manufacture of brass. The recommended daily allowance for adults is 15 mg zinc/day. Metal fume fever associated with inhalation of fumes of ZnO is characterized by fatigue, chills, fever, myalgias, cough, dyspnea, leukocytosis, thirst, metallic taste and salivation. ZnCl2 inhalation results in edema in the alveolar surface and the protein therein the lavage fluid is elevated. Particular pathological changes associated with zinc intoxication include: pale mucous membranes; jaundice; numerous Heinz bodies; and marked anemia. Adequate ambient air monitors for permissible exposure limits, excellent ventilation and extraction systems, and approved respirators are all important in providing adequate protection.
Just total nonsense, been working around zinc baths for 42 years and never had any of your symptoms. Just don’t put rubbish on here that you have no knowledge about

Yes indeed, companies do that, they do hot dip galvanization to give best results and corrosion protection to vehicle chasis. It can protect your vehicle chasis from rust / corrosion for a long time.

@@KeoN710 if they flipped it, the bottom of the flang would be a smoother finish, yes there will still be some build up and drips near the edges but on no critical surfaces, with a flip it can be can be cleaned up with a hammer, nothing to grind that way
@@Kyle_Harding Bro i'm a crane operator at the kettle, trust me.
@@KeoN710guy I've poured maple syrup on my pancakes once or twice, trust me, a flange doest help aunt jemima have less drips
If it was flipped it would have a few drips on the top edge of the flange, but it would be much better then a large build up of zinc on the bottom mounting surface, this way it would need to be ground back to being flat.
Just as long as the process is not done in China.
They do not do the quality of plating US companies do.
The coating the Chinese use on the inside of galvanized pipe wears off quick, 2 years from domestic water and as well as inside when used outside for gas piping, the coating flakes and gets into gas regulators, gas valves, orfices etc.
The Chinese pipe is usually sold at box stores.
@TheSushiraw than why so many other countries copy our engineering?
Lol. Lol. Lol. Lol. Lol. Lol. Lp
Lol.
China sure does not engineer ANYTHING. LOL LOL.
If you call copying something engineering?
@TheSushiraw than why to our country for school?
Stay home
@TheSushiraw wasnt aware other countries were civilised yet?
Must have stold our engineering and ideas
@TheSushiraw the only engineering China has done is cv-19 and chicken fried rice with egg roll
What are the components of galvanizing
zinc
Video about dipping into zinc - video does not show dipping into zinc!
I’m a dipper in FL I got some really cool videos
if am not wrong in hot dip galvanizing process the entire metal has to dip in one go not like up and down coz It might get crumble on the long type metals due to hot dip in one side and cold on the other side
It depends on the part. Some parts like handrails you have to stop occasionally while going down with them otherwise air builds up too fast and they float. Then they REALLY look bad. But on the way up its much preferred to do it without stopping. Otherwise you get those horrid flaky lines across the parts.
So why is welding galvanized so dangerous? I thought theyd be wearing respirators and such!
Antiquated equipment, slow processes. Are they making any money?
wait until you see my new plant this year. it is doing good , at the end of the day, its the quality that counts and the bottomline is good too

What happens if I swim?
they wont find your trace
Its ver nice and clear explanation thankyou very much . Janardhanreddy
Imagine one of those wires bracking and a pole falls into the galv and it spalshes onto the poor workers, crazy crazy saftey issues here!!
Well.. you'll got yourself a rust proof armor
@@zeezeazee omw to apply for a job in galvanizing plant
We opened the fume en splatter board for video purposes only.. which slides during galvanizing
Normally it is enclosed to avoid splattering workers.. no workers within 15mtrs of the galva tank during galva
Where from?
no safety catches on crane hooks?
Thanks for uploading such a knowledgeable video...
Thank you.
thank you for watching
Kaun sa jagah hai
Looks really cool, but it's such a "dirty" process. It's relatively easy to coat the outside, but coating the inside is typically the challenge. There are new methods available that are faster and cleaner than this - but they are not on the market yet!
like what methods? can i manufacture something with iron or steel and then galvanize it?
What new methods? There is electroplating but that's almost as old as galvanising.
Why do people make stupid comments like this? Are you trying to sell me something?
At one of the valmont plants someone was in a kettle explosion that guy lost his leg and over 90% of his body was burned he survived but the only thing that saved him was his face shield
Amazed at all the different variations on comments of the way it’s done.
Got a serious problem with that video camera of theirs constantly going out of focus here!
Yep, turn off the auto-focus and leave on Manual. Both shots were from about the same distance. And a little editing wouldn't hurt either. Watching that large cover creep over the tank was way too long. Still a cool video!
Glenn Brown what’s the cover needed for?
Is that slag they are scraping off?
2:20 for the moneyshot
Why??
Guessing we don’t do this in the USA anymore?
They do this a 10 minute bus ride from my house.
This is what we use for
Our push piers for my company. This steel is used to
Ships!
Now we just need an exo-friendly wood veneer tutorial
Good work
Can I swim in it?
Yes,for sure,it is perfectly safe and you will never corrode afterwards.😎

Missed the explosive sounds dropping into dip
I wanted to see this as well. My brother told me this story he was told, where they'd drop the metal parts in quickly when they had visitors just because it was impressive.
@@jonwelch564 we cant do that tho. Would blow of the whole company with our material and bath sizes
Qual contato de vcs
So you don't use EPP for the toxins
Why would you skip over the ACTUAL DIPPING part?
I worked in hanjin 2 yrs in galva
Watching the video was good enough so long I did not find people coming so close to molten zinc tank and manually saperate or shake the beams apart. Sorry to mention, the Safety part of production is in questionable be it from a developing or developed country. We belong in such time zone when Mars and moon being explored, automation proccess is highly expected around these areas of production.

Wow so cool!!
Not cool to Hot 460°c temp of this zincbath
People gotta stop using auto focus. A camera just can’t know for sure what you’re trying to look at all the time. You twist that lens, you’re all good.

What a process fun watching this stuff
thank you. Though the comments here made us do some more improvements
After completing galvanising on pole zink line produced how it avoid
could you do this with car
Porsche was the first company to do this with car bodies.
In the Netherlands the Coatinc Company does this with parts of VDL busses 🚌.
I wish I could see the dipping part, I wish you hadn't cut it out 😭
It’s pretty interesting but your not aloud to be anywhere near it
yes... nobody... but a camera can do it, and yes maybee not 1m near... maybee 10m away with zooming?
I work at a galvanizing plant in Florida I’m the dipper it’s really cool if you go fast when you dip It’s super cool
@@chillinwithmike4699 what's galvanized? It makes metal shiny?
@@nickr3441 galvanising is Basically coating of zinc on other metal substances to protect them from rust.
What is the second tank for?
Normaly cold water because the first Tank have 450 degrees. The Metal goes after the Dip to the outher Station and people clean this.
two possibilities, water or passivation.
well due to the color of this water, it might be just polluted by steel or it might be a passivation wich is a chromic solution, so the zinc wont oxydize after that , or in time it s the chrome who oxydize before the zinc
sorry for my english
Slightly confusing that the crane beam used to hot dip galvanised steel is rusty!
DANBEED That’s called ironic not confusing.
If it were galvanized it would weaken the acid used to “pickle” the steel resulting in a considerable amount of money over time
its galvanized and painted
@@philgalvindustrial9381 That's surprising. I would have thought with the heat and the application that you wouldn't want to paint the beam. It's galvanized after all.
Brothers give me location
All they have is and eye protection hood?
Most of the commercial production of zinc involves the galvanizing of iron and the manufacture of brass. The recommended daily allowance for adults is 15 mg zinc/day. Metal fume fever associated with inhalation of fumes of ZnO is characterized by fatigue, chills, fever, myalgias, cough, dyspnea, leukocytosis, thirst, metallic taste and salivation. ZnCl2 inhalation results in edema in the alveolar surface and the protein therein the lavage fluid is elevated. Particular pathological changes associated with zinc intoxication include: pale mucous membranes; jaundice; numerous Heinz bodies; and marked anemia. Adequate ambient air monitors for permissible exposure limits, excellent ventilation and extraction systems, and approved respirators are all important in providing adequate protection.
juliusvalentinas No OSHA there. Maybe China?
Just total nonsense, been working around zinc baths for 42 years and never had any of your symptoms. Just don’t put rubbish on here that you have no knowledge about
