Almost every company, producing cars, declares that equips his models galvanized. First of all, this is evidenced by advertising prospectuses in which it is beautifully painted, how long the car serves you faithfully. However, in fact, everything is easily different. In this regard, every car enthusiast should own information on how to learn galvanized body. This will help not get caught on the bait of cunning marketers and.
The role of otsinkovka
Currently, there are three types of galvanizing autocuses that apply car manufacturers - thermal, cold and galvanic. Under cold technology, the high-quality staining of the entire paint car, which contains a finely dispersed zinc is implied. Any galvanized suggests.
The fact is that the metal from which the car body is produced, even the highest quality ,. This is due to its constant contact with moisture.
Usually in advertising automakers talk about galvanizing autocosov, in fact, they mean the galvanized only by its individual parts, the most vulnerable. Most often, the most vulnerable to corrosion elements of the car are the bottom and thresholds.
Determine galvanized body
On the video there is a corpus of the car body of the Niva:
So, in order not to stay in the fools after and after a few years, do not discover rust on the body, first of all you need to be attentive to detail and do not give the sellers to talk to your teeth.
If you set yourself in the auto show, how to find out, whether the car you liked galvanized, then to start, look at its technical characteristics. Fully galvanized only in the case when "complete galvanizing" is written there. Any other inscription indicates that the vehicle of the car is protected from corrosion only partially.
Incomplete protection also says the cost of the car. Autocuses, as a rule, are treated with inexpensive materials and paints. Such a car includes multi-sieves economy options for Asian manufacturers. In this case, you will not be able to check the truth of this statement, since the test on the galvanized will cost you in a round sum that you can add to the cost of a cheap car and buy yourself something better.
When buying a car of Asian or European manufacturers, you know that its body, most likely passed electroplated galvanized.
Thermal processing passes cars marks, Volvo, Ford. They are perfectly protected from corrosion and impacts of road chemicals.
The giant of automotive industry for the production of bodies of its cars uses special material - zincometal. It makes the car more reliable, and its service life increases several times.
Together with the description technical characteristics Automars when buying it you get warranty couponwhich indicates a warranty on galvanized autocuses from through corrosion. This is a very important document, which, in the case of a defect, can be present and obtain a considerable amount to eliminate it or exchange goods.
Many motorists are interested in whether the body is galvanized and is it possible to do it yourself. Experts argue that checking the presence of galvanizing the vehicle of the car and its quality can be only on special expensive equipment. It is not attended by every hundred, not to mention the personal garages. Just to satisfy your own interest. The study of this body characteristic of the car will cost you in a round sum.
It suggests a conclusion: look less and and more carefully study the technical characteristics and warranty card you liked the car. Exactly at small details You will find most of the answers to your questions, including about the galvanizing of the autocuses of this model. Also pay attention to the manufacturer and the cost of the car.
The body of the vehicle is the almost most expensive element of the car. In our climatic zone, he constantly has to be exposed to the temperature differences and suffer from precipitation. Tired constantly handle the body of the machine with anti-corrosion means, motorists when replacing cars wish that the new "car" the body was galvanized. Many automakers indicate that their cars are covered with zinc. Worried, it seems, there is no reason: the car with such a coating is not subject to corrosion. But, unfortunately, with a zinc layer on the elements of the car is not so simple, since the cheap "Chinese" in this case would not be different from or.
How to choose a car with galvanized body
Decided to buy such a car, should be able to competently choose the machine model, for galvanized TS zinc are covered different ways: Some models can be completely protected from rust, others are protected only by individual elements, and others are only coated with a primer with a content in its composition of a meager amount of zinc.
Very high quality galvanized are covered with such car brands: Volkswagen, Porsche, Audi, Skoda, Volvo, Opel, Ford, Mercedes, BMW. Honda legends, Pilot, galvanized only the bottom, wings and thresholds. Automakers of Lada Marks, Jil, Junta are used in zinc primer. The quality of the galvanization of the vehicle and, naturally, its price, depend on the type of galvanized.
Types of otsinkovka
The galvanized layer will perfectly protect the metal from rust and extends for a long time the life of cars. The types of galvanizing are the following:
Hot otsinkovka
Her advantages:
the metal subjected to this method of galvanizing perfectly opposes corrosion about 15-30 years.
This is 3-4 times more reliable than electroplating coatings.
Galvanized steel steel resistant to mechanical damage damage.
Minus such a kind of galvanizing - high cost. This is essentially the cause of the high cost of such cars.
The VW Group autoconecern produces such cars such as: Volkswagen, Audi, Seat. Motor transport from the Volkswagen Group concern is tested for corrosion resistance in salt chambers. But such cars are protected from rust in different ways.
Audi is more resistant to rust. From the mid-80s of the last century on the metal, from which the body of the Audi is manufactured. The galvanized is applied on both sides, even on the seams.
A hot way is applied galvanizing and Volvo, Chevrolet, Opel and Ford. In many parts of aluminum, and when the elements are protected from zinc steel, they do not regret.
Galvanic otsinchen
This method of applying zinc is known for a long time. Each of the automakers has its secrets. The successful galvanizing composition was able to invent manufacturers of Mercedes cars and BMW. The thickness of the galvanized layer on the car body is 9-15 microns. Galvanized by this method, metal in resistance to rust can be sacrificed with Audi. After the galvanization was performed, the metal becomes smooth and paint perfectly lies on it.
A car from Japan is not the best in terms of anti-corrosion. On cars from, pilot, CR-V are installed only by some galvanized elements: it is usually the bottoms, thresholds and wings.
Zincometal
Kia autocontracene went his own way. The body elements of the machines of this autoconecern are made of zincometal, resembling a "puff pastry":
Nizhny - steel;
Medium - mixed oxides with zinc;
Upper - organizing with a large content of zinc.
Cold Ocinkovka
Such a type of galvanizing - marketing strokewhich was invented by manufacturers budgetary cars. Cold galvanizing is the coating of the elements by the katofanese soil containing zinc. Thus, galvanized: Lada, Chery, Höndai and some models of Kia.
Definition of the type of galvanized
There are special equipment with which you can find out, galvanized or not a selected car. But such devices are expensive, and see them not in every car service.
With a thorough study of documents on a car, you can learn galvanized body.
1. Cheap cars are neither hot, the more in the galvanic method is not galvanized.
2. If the instruction indicates that the car is galvanized, then this means:
Its individual elements are treated with zinc-containing primer.
3. vehicle The zinc is covered correctly only if the instructions indicate that the car is completely galvanized.
Each driver of the car conceived, how to protect your car from corrosion exposure. As soon as corrosion appears, it immediately becomes visible, and the car no longer looks beautiful and presentable.
What ? This is the process of transition of the metal into its usual initial state, how it is in the earth's crust. As it becomes clear, it is a completely natural process, and therefore it is completely impossible to stop it, but modern inventions and technology will help you slow down this process.
It quickly passes with various influences, such as electrochemical, biochemical and chemical. All these processes occur upon contact with environmentalAnd therefore, before the driver, the car rises the task to protect the metal from such contacts. For this day, there are two popular methods for slowing the corrosion process - the use of electroplating coatings and anti-corrosion processing.
Most often zinc applied as a galvanic coating, and therefore now there are cars with a galvanized body. Such cars, of course, will serve longer, but they corrode them faster. Zinc will save from corrosion only on smooth and smooth surfaces, but in places such as joints and edges, he will not help you.
Therefore, cars with galvanized will serve you for a long time if zinc becomes only part of a common barrier, and not its basis. Be sure to apply this approach to Second-Hand cars.
Do not forget that it is even necessary to periodically expose to inspection and anti-corrosion processing, otherwise the car will quickly come into disrepair.
If you still decide to choose a second method, the method of processing the auto anti-corrosion agent, you can not worry about choosing - there are many various means for processing. In the time of the USSR, such materials practically did not go to our market, only the Anticorrosive "Movil" appeared, they needed to be used for hidden cavities.
Already at the age of 70, anticorrosors appeared from the West, but not every resident of the USSR could from acquiring, since the cost was rather big. Now there are a large number of anticorrosers, but remember that for high-quality corrosion sewn it is recommended to carry out treatment on a special service station, where you will be offered only the best anticorrosions from world manufacturers.

If you know what you can add a list - write in the comments.
Any car is maintainable. Replacing not only standard consumables, but also key nodes designed for continuous operation are subject to replacement. Because sometimes on the car is changing not only the oil and filter, but also motors and gearboxes.
There are a number of elements that are not so difficult to replace as needed. But the same thing cannot be said about body details. Conditionally the most simple in the replacement doors, hood and trunk lid. It is quite another thing when changing the bottom or rack. It is almost impossible to do it.
At the same time, the body is subjected to the strongest impact of various provoking factors, including mechanical damage, contacts with chemical aggressive substances, water, moisture, snow, sand, etc. The formation of even a small focus of corrosion over time can lead to a significant growing rust throughout the machine. It is imperative to provide the body a high level of protection. Paintwork with such tasks copes badly.
Most effective way Corrosion fighting rightly considered metal coating with zinc layer. This procedure is called galvanized. Moreover, the highest quality galvanizing occurs in the factory industrial conditions. The level of galvanized is largely reflected on the durability of machines. Some rust literally in 5-10 years old, others are quietly exploited for 30-40 years, without making their owner to invest a huge amount of money in combating corrosion and repair the body.
What is zinc
It is also a thermal processing method, but already requiring smaller resources and financial costs. Therefore, the method was widespread, and find cars with such a body much easier.
Basically, Japanese and American automakers were switched to electroplating. It is noticeable to meet them less often among European companies. Given not the highest efficiency in comparison with hot galvania, the leading automakers develop improved zinc methods, modernizing the galvanic principle. In particular, these are companies such as Mercedes and BMW.
In order to improve the quality and efficiency of galvanizing, the following steps are used:
- In the production of themselves body details Apply high-alloy steel grades. Their advantage is that the number of impurities in such a minimal one.
- It is applied a thicker layer of zinc itself. Thickness can be from 9 to 15 microns.
- In addition to galvanizing, the body is additionally ground with a thick layer and thicker layer paint coatingapplied from above zinc.
- The adhesive properties of surfaces increase, ensuring a stronger and durable bond between all layers.
Before publishing, which have galvanized car galvanic technology, it is worth noting one regularity. Japanese cars were initially inferior to European in the quality of the quality of galvanizing and body durability. But then the situation began to change, and they came out about one level. This was due to the fact that the Japanese began to use a zinc somewhat later to produce cars.
Cars are most qualitative toyota brands and Lexus. They demonstrate excellent indicators corrosive stability. In many ways, due to a sufficiently thick layer of the protective coating.
The galvanic method of galvanizing autocuses was used in the production of such cars:
- Alfa Romeo (only after 1993).
- Audi A4.
- Mitsubishi Lancer 9.
- Mercedes W124.
- Mercedes W201.
- Lexus (all models).
- Volkswagen (all cars after 2000).
- model a number of Toyota. (after 1991).
- Skoda Fabia.
- Skoda Octavia.
- Peugeot.
- Honda Legend.
- RENAULT ESPACE 3 generation.
- Renaul Logan.
- Chrysler 300m.
The same Renault Logan. It has far from the exemplary quality of the paint and varnish coating. But at the expense of a good level of protection by galvanic galvanizing, their body can be under the attack of moisture and chemical reagents for a long time, not allowing to appear corrosion foci.
Situation with domestic auto industry
Many motorists are naturally interested in domestic cars that go with a galvanized body. Some even doubt whether they exist at all.
The overall picture with the galvanizing domestic machines looks pretty bad. Previously, cars of the AvtoVAZ family were assembled on the basis of ready-made elements that were transported from other countries. At the same time, some components are quite likely to be made by pre-galvanizing the metal, but it was not mass production.
Even with the absence of an anti-corrosion factory coating, the details of imported suppliers turned out to be unprofitable, the cost of production of cars was high. To reduce prices for russian carsIt was decided to transition to domestic steel.
If you come back to the question of which cars in Russia are available with galvanized from the plant, then here you can say the following. The galvanizing began to apply everywhere. The only question is which method used. And the technique was used cold. As you already know, in terms of efficiency, this is the weakest version of galvanized. Plus, only individual components underwent galvanizing. Here is the answer to what cars in Russia are processed completely. The whole galvanized cars among the Russian auto industry are actually absent. Their list is simply not from what.
Currently, the so-called cata reform method of anti-corrosion treatment can be used in the manufacture of machines, in which Zinc is not used at all.
Machine galvanizing at the factory
Alas, but to say for sure about where there is or where there is no zinc layer, it is impossible. This information is usually hidden or disclosed partially. It does not allow to say what chinese cars May be galvanized body. Surely partial processing is on all machines. If we talk about, then the following facts can be given here:
- On VAZ 2110 cars and its family (VAZ 2111, VAZ 2112), about 30% of body elements have been diagnosed.
- Niva or Lada 4 × 4 has an exclusively cata referred primer layer. Zinc compositions do not apply here.
- Lada Kalina. On the first generation, about 52% of galvanized elements used.
- On the second generation Lada Kalina applies conditionally complete galvanized, since the corresponding layer on the hood, spars and no roof.
- Lada Priora first had 29% of galvanized body details, and since 2009, zinc was applied to all metal elements.
- Lada Granta in the body of Liftbek can boast galvanized doors and wings. In the body, the galvanian sedan is not provided at all.
- Lada Vesta is galvanized conditionally completely. After all, the special protective composition was not applied on the bottom and thresholds. Plus, in the body, the sedan did not for some reason to protect the roof.
- Lada Xray, like Xray Cross., it is almost completely zinc. The exception was only the roof.
Among domestic carsmanufacturers until 1999 such a concept as galvanizing in the manufacture of cars did not exist at all. Only since 2009 the company switched to the cold processing method with zinc. Moreover, in the overwhelming majority of cases, only a part of the components were covered. A partial method of treatment is applied not only to the factories of AvtoVAZ, but also at UAZ, gas, etc. to great regret, the desire to reduce the cost of production makes it possible to use an exclusively low-efficient method of anti-corrosion protection. Therefore, an oxidizing process is quickly launched on the domestic car when the oxidizing process is quickly launched, if this is noticed in a timely manner and do nothing.
Is it possible to learn about the presence of galvanizing on the body
Autolokers are fairly interested in buying a car with high-quality and corrosion-protected body. Immediately be prepared to overpay for such an advantage, since the treated machine with the same characteristics and equipment will cost more.
There are no serious obstacles in order to find out if it was applied protective covering On a new or used car, and which method was used. To trust the sellers is definitely impossible, even if they assure you in and exclusively in the use of hot galvanizing. Everything needs to be checked.
The simplest and at the same time affordable method is the study of technical specifications. Information can be found in the instruction manual, or simply explore the story. specific model In a concrete body. If nowhere is mentioned by the concept of galvanizing, probably not the processed elements, or their minimum amount. Others write that the body is galvanized, but they do not say which specific components are processed. You need to search for cars where they declare about full zinc. This makes it possible to assume that such a car was treated at the factory entirely, and not partially.
In the overwhelming majority of cases, you will collide with partial body zinc. And most often it is a galvanic method.
There are no tools or ways to allow you to determine the degree and type of the factory anti-corrosion coating. Some auto services with appropriate expensive equipment offer a car research service for galvanized. But to meet such a hundred pretty problematic, especially in Russia. Plus, the service is too expensive, and few are interested in purchasing it.
Summarizing
From all of the above, it is previously we can say that most often on the market there will be machines with a galvanic method of anti-corrosion bodywork. The thermal or hot method meets much less frequently. Although German auto hydriants are actively working to reduce the cost of hot galvanizing. It really gradually approaches the price for high-quality galvanic processing.
About one defense method has not been said. This is a zincometallic method. But it is not necessary to talk about the high characteristics and properties. Only some manufacturers use such a method. The most famous of them is the South Korean brand Kia.
Board for those who buys relatively new car. Each automaker issues a warranty card, in which the warranty period is prescribed. through holes In the body caused by the impact of oxidative processes (corrosion). If such defects appeared earlier than the manufacturer provided for, it is possible to officially require compensation in the form of free repair. Sometimes companies go to more serious steps, replacing a defective car to a new one. After all, the factory marriage can also be eliminated, and not all cars of one model and even release dates have a completely identical level of anti-corrosion protection.
The car body is made mainly of steel. And steel is such a thing that is rather quickly rust. To slow down this process, the body is painted and covered with varnish. But the paint is a unreliable thing: a small accident, dry branches of bushes or chip, and now there are no paints, and the body is not protected. Therefore, they came up with galvanized.
Panacea thin layer
Zincovka is when the steel is covered with a thin layer of zinc. You can do this in different ways. Some ways are better, other worse - about it through a couple of paragraphs.
The fact is that when the body remains without paint and varnish (for example, in place of the chip), corrosion begins to destroy zinc, and not steel, the rust does not appear. But it is only for the time being, because when zinc is destroyed - and sooner or later it collapses, - corrosion starts to destroy steel.
How long the chip will be without rust depends on many factors, and not only from the quality and thickness of the zinc layer. For example, from humidity and temperature. In average, the rate of destruction of the active zinc layer ranges from 1 to 6 μm per year, and the thickness of the zinc coating on different machines ranges from 2 to 15 microns. Faster corrosion occurs where it is humor. Or, for example, under nulipiled mud.
Hot otsinkovka
Now about anti-corrosion processing types. The best galvanized is hot galvanized. With this method, the body is lowered into a bathroom with hot (from 500 to 4000 degrees Celsius) zinc. The zinc layer is usually about 10-15 microns. So galvanized mainly dear cars And that is not all, because it is a rather complicated and expensive process. Body warranty, galvanized in this way, is usually from 15 years. And if only the guarantee is such, the body can be considered almost eternal. Examples of hot galvanizing machines: Most modern Porsche, Audi, Ford, Volvo models.
Galvanic otsinchen
The second way of galvanized is galvanic galvanized. It is cheaper and common. Most galvanized cars are galvanized in this way. The body is descended into the zinc-containing electrolyte, through which the current is passed. As a result, a very uniform galvanized with a layer from 2 to 10 microns is obtained. Corrosion guarantee on such a body is usually in the area of \u200b\u200b10-12 years. In this way of galvanizing, almost all manufacturers are not budgetary cars: Opel, Toyota, Mazda, Volkswagen, Mitsubishi, Chevrolet, Nissan *
Cold Ocinkovka
This type of galvanized was widespread not so long ago. At about the same period when the ball began to rule not engineers, but marketers.
The technology is to mix highly dispersed zinc powder into the soil. Galvanized body B. this case It can only be considered formally, because zinc, in fact, not on the body, but in the soil. No soil (if scratched to metal) - no protection. Anticorrosion protection of such a "galvanized" is very small. The manufacturer does not give a big guarantee for the body in this case, is also limited to the general guarantee of the LCP. In this way, they are galvanized by most of the budget cars: Renault Logan, Lifan, Chery, Great Wall, HYUNDAI, RENAULT LOGAN, UAZ, VAZ.
Zincometal
This type of galvanized is rare and only among a small number of inexpensive models. The essence of the method is that steel is covered with zinc soil at the rental stage. The protective properties of this method of galvanized cannot be called outstanding. Especially bad defense will be in places where it is wet and after accidents and damage. In this way, galvanized mainly by the KIA, RENAULT brand machine.
It is important and what processing was at the body: complete, partial or only nodal connections. Naturally, it is best when the whole body is galvanized. But for the manufacturer budget cars And this is expensive models, so they are often circulating partially. For example, only wings, thresholds.
There are absolutely economical automakers that cover each precade, only nodal compounds (welding seams and attachments, for example).
As you can see, galvanizing galvanizing, and for each specific model requires clarification. On the Internet, you can find information on how and what years of the release has been galvanized for a particular model (and was galvanized at all). Sometimes, for example, in the case of "Logan", in the first years, the galvanized was partial, and then complete.
In general, from all this should be done two conclusions. The first - rust even galvanized cars. Moreover, rust at different speeds depending on the weather, caringness of the owner, temperature, external influences of the type of reagents and dirt and so on.
The second conclusion is not to believe the statement of marketers that the body is galvanized. It can be purely galvanized, and it is necessary to look at the facts - on the method of galvanized and on the manufacturer's guarantee on the body. The more guarantee, the better, probably galvanized body.
* Information is collected from open sources and may contain inaccuracies. The method of galvanizing may vary from year to year, from the factory to the plant, from the model to the model. For accurate information, you need to look for information on a specific model, year of issue and plant.
