Renault Logan what the body is made of. Is the body for Renault Logan galvanized or not? Galvanizing body Renault Logan

For our country, the rapid decay and erosion of car body parts is the number one problem. High humidity, constant temperature changes, the use of aggressive anti-icing reagents quickly do their job and make the metal unusable within a couple of years. Today we will talk about how Renault Logan engineers found a way out of this situation, and how a galvanized body can help the car owner.

Why is this needed?

At the moment, to protect the car from corrosion, there are a number of different ways. For the most part, all of these methods come down to just two.

The first option is to use as many polymer moldings as possible on the body, which reliably cover most of the "problem" places and completely exclude the penetration of moisture to the metal, which does not have an anti-corrosion coating. The second way is to cover the body, bottom and arches with special compounds that preserve the metal and thereby prolong the life of the car many times over.

By purchasing Renault Logan, you can make sure for yourself that there is no reason to worry about the bottom of the car. Indeed, even from the factory, this sedan is coated with a factory anti-corrosion coating, which is able to endure with dignity all the hardships of our climate for at least five years. Next, you should cover the bottom again and provide a few more years of guaranteed absence of corrosion.

If the bottom of the Renault Logan is securely protected, then what about the rest of the body? Car owners are well aware that over the course of operation, literally five to seven years after active car trips, the fleeting “eating” of the wings, the bottom of the doors, the hood and the trunk of the car with corrosion begins. Moreover, if you start this situation and do nothing to remove rust and preserve the metal, the rust quickly develops into through holes and leaves no chance for the machine element to recover.

A layer of zinc, which is not found on most budget cars, is applied under the paint layer. It completely prevents reaction with moisture and salts, so the manufacturer of such a machine boldly gives a guarantee for 8-10 years of the absence of through holes. This technology is used on the vast majority of European cars, from cars to large trucks.

A little specifics

Renault Logan owners have a logical question: is the metal on this car galvanized? Is it worth worrying about the condition of your car when operating it in cities where aggressive chemicals are used to clean the streets in ice?

If you turn to the official documentation for Renault Logan, you can quickly find lines stating that the Renault Logan body has a zinc layer that meets all European standards. However, the owners themselves claim that on the first generation, the rusting of the arches and the bottom of the doors occurs as quickly as if the metal were not galvanized. What's the matter?

It turns out that the first generation has a number of elements that are not galvanized. Summing up simple statistics, we can draw the following conclusion. About 60 percent of the body, indeed, does not have a zinc layer. Otherwise, the cost of the machine could increase significantly. True, when developing the second generation, this problem was solved, and now the sedan has more than 90 percent of galvanized elements.

Summary

Renault Logan has reliable protection against aggressive external influences and decay. However, an excellent preventive measure is to periodically check the machine and timely conservation of problematic sources. This will repeatedly extend the life of the car and protect the car from through holes.

When buying a car, people must specify whether the manufacturer has provided for galvanizing the body or not. The reasons for this interest are clear.

Galvanization prolongs the life of the metal and reliably protects against corrosion.

What other advantages of galvanizing are worth highlighting? How to determine if the body is galvanized on Renault (Sandero, Logan or Duster), Lada Vesta, Ford Focus, Opel and other models? What methods of galvanizing are in demand? Let's figure it out.

Advantages

The power part of the car is characterized by a large resource, estimated at hundreds of thousands of kilometers. In this case, the weak link is the body.

After 2-3 years of operation, rust appears on it, which requires urgent repair and subsequent tinting problem areas.

To extend the life of metal, car manufacturers and motorists resort to metal galvanization, which provides the following effect:

• Resistant chemical protection against external influences;
• Resistant to moisture and chemicals. The coating of the metal base with zinc guarantees reliable protection of the body and gives the motorist a chance to forget about the problems of operation.

On the other hand, there are a number of disadvantages here:

• Full galvanization is a minus from the standpoint of ecology. Scientists have proven that such coatings are harmful and affect the state of the atmosphere and human health;
• Body elements coated with galvanized sanding and stripping is prohibited. Otherwise, the treated area is instantly covered with a layer of rust.

There are situations when paint lags behind galvanization. It requires the involvement of craftsmen who will remove the necessary layer and properly process the surface.

Recently, a myth has been circulating that galvanized metal does not rust at all. This is not true.

In practice, galvanizing inhibits corrosion, but even without an additional layer of zinc is not a guarantee of salvation.

Few people know, but the zinc layer is a couple of microns, which does not allow protecting the body part from chemistry.

Zinc "shield" of any car, be it Lada Vesta, Ford Focus, Opel or Renault (Logan, Sandero, Duster), decreases over time.

Mechanical damage, such as stone impact, accelerates the corrosion process. But that's not all.

During operation, the metal is subjected to vibrations, shocks, which leads to the appearance of microcracks, dents, which act as an aid to the onset of corrosion.

We must not forget that galvanizing galvanizing is different. Here it is worth highlighting the following options - full or partial, one-sided or two-sided.

At the same time, the methods of applying a protective layer also differ (more on this below).

In addition, each car has a group of hidden elements - racks, boxes and thresholds, where rust appears first.

So the treatment is good only in combination with additional treatment with an anti-corrosion compound.

How is galvanizing done?

As already mentioned, several galvanizing methods have been developed. Among them:

1. Galvanic.

The principle here is to dip the metal elements in a prepared electrolyte with a high zinc content.

The galvanic type of processing is popular with manufacturers in Europe and Japan. But here it is worth highlighting a number of nuances.

Full processing involves the coating of all metal elements of the body.

If there is no such prefix, then only some elements are processed - thresholds, bottom and others that are more susceptible to rust.

But in both the first and second cases, the fact of galvanization is prescribed in the technical specifications.

Parameters of galvanized zinc coating:

• Zinc coating - 5 microns;
• Two layers of soil - 5 and 20 microns;
• Base - 10 microns;
• Lacquer - 20 microns;
• Base - 10 microns;
• Lacquer - 20 microns.

2. Cold galvanized.

This type of processing is considered popular by a number of European and Asian manufacturers.

The principle is a two-stage processing of the body:

1. Surface coating with phosphate salts of iron, manganese or zinc;
2. Application of primer or paint with the addition of fine zinc to the composition.

Cold galvanizing equates to high quality painting.

Masters say that this method of galvanizing - marketing ploy. At the same time, it does not provide reliable protection against corrosion in case of violation of the integrity of the paintwork.

Characteristics:

• Zinc-containing primer - 10 microns;
• Two layers of soil - 15 and 35 microns;
• Base - 15 microns.

3. Hot dip galvanized.

This type of galvanizing is carried out on one or both sides. In this case, the methods of applying a protective coating are as follows:

• Immersion of a body element in a molten zinc solution;
• Applying a protective composition to the body sheet at the stage of rolling.

It is believed that hot-dip galvanizing guarantees the effect and resistance to corrosion. It is popular with manufacturers Ford, Porsche and Volvo.

Options:

• Zinc coating - 12-15 microns;
• Two layers of primer - 20-30 microns;
• Base - 20 microns;
• Enamel - 40 microns;
• Lacquer - 5 microns.

How to find out if the car body is galvanized?

When buying a car, people specify whether a galvanized layer is provided on the body or not.

There are two ways to determine:

1. Exploit opportunities special equipment.

For a single application, this option is not justified, because the cost of the device is high. In fairness, it should be noted that not even all service stations buy such devices.

If the device is at the disposal of the service, then the cost of the check will be such that it is easier to add money and purchase a car whose body is galvanized exactly.

2. Study of technical documentation.

As a rule, manufacturers indicate the presence of galvanization and type. In addition, it is prescribed whether the body is fully galvanized or only partially.

When choosing the second option, consider the following rules:

1. On cheap cars, the method of galvanizing or hot-dip galvanizing is not used due to the high cost of the process;

2. If the manual says that the body is galvanized, then this may indicate the following:

3. The car is galvanized in compliance with the rules only in that situation, if the instructions indicate complete processing.

4. Do not forget to go online and check if the car body is really galvanized or if this is a sales pitch of the seller in order to get rid of the “iron horse”.

Below we consider some models and nuances of galvanization:

1. Renault Sandero has a partial bodywork. Type - zinc metal. During processing, a layer of oxides containing zinc elements is applied. Protection is enough for an average of 5-6 years.

   

2. Renault Duster has a partial processing. Type - micrometal. It uses the technique of spraying a layer containing zinc particles or applying protection at the rolling stage. The quality is acceptable, but the first corrosion often appears after 2-3 years.

   

3. Renault Logan. The latest models, starting from 2013, are fully processed. Method - galvanic (two-sided) galvanization. The principle of operation is to immerse body elements in zinc electrolyte and apply current. The final layer of zinc spraying is 9-15 microns. The average service life of a body without corrosion is 7-8 years.

   

4. Hyundai Solaris. The body of these cars is processed by cold galvanizing. The method involves coating with zinc content. The average service life without corrosion is 4-5 years.

   

5. . Since 2014, the manufacturer has been using the method of hot-dip galvanizing of the entire body. The principle is to immerse metal elements in a zinc composition. The finished assembly has a zinc layer with a thickness of 2 to 10 microns. According to the developers, the first traces of rust will appear only after 20-22 years.

   

In the conditions of the domestic climate, one of the most global problems that the vast majority of owners have to face is the tendency of the Renault Logan car body to corrode. The appearance of this negative factor has an activating effect:

• humidity;
• temperature jumps;
• the abundant presence of reagents designed to deal with icing.

This is not the whole set of aspects that can turn metal into a material that has lost its strength.

Here we will pay attention to the measures that the engineers used when creating Renault Logan, and whether the body is galvanized, all this can come to the aid of car owners.

What is it for?

Today, auto manufacturers have a whole range of measures in their arsenal to ensure the safety of the body panels of their offspring from corrosion, but many are interested in whether the body is galvanized before buying a car, because this is an excellent protection for the car. Globally, all these methods fall into two categories.

The first option is to place as many moldings and other protective polymer panels on the body elements as possible. This allows you to secure multiple "problem areas".

As a second method, a special body coating with certain compositions is used. Due to this kind of conservation, the body metal is able to “live” for quite a long time.

If the future owner has planned to purchase Renault Logan, then he should not have concerns about the durability of the bottom. At the factory this car acquires a reliable anti-corrosion coating, which makes it possible to resist with enviable dignity the whole galaxy of hardships with which Russian climatic conditions are saturated. The guaranteed period of preservation of protective properties is approaching five years. Next, you need to update the coverage.

We figured out the bottom, but what can you tell about the Renault Logan body panels? The owners have already noticed that during 5-7 years of intensive use, the fenders, lower door edges, hood and luggage lid are subjected to a fierce attack of the “red disease”. If countermeasures are neglected, then corrosion can turn the body metal into through holes, depriving the owner of the hope of restoring the elements. How to understand whether the body of the model is galvanized or not?

The zinc protective layer, which most "state employees" are not able to boast of, involves its application before direct factory painting. This coating is able to prevent the metal surface from reacting with salt impurities and moisture. Manufacturers of such cars provide guarantees for the safety of the body from through holes for up to 10 years.

Galvanizing technology is very common among European and Japanese manufacturers, even among middle-class cars, no one is worried about whether the body is galvanized or not, of course, yes. Not only cars, but also commercial trucks are processed with such a coating.

Let's get specific

Renault Logan owners have long been concerned about a logical and topical question: is the body galvanized or not of their native car and should they spoil their nerves for worry about exposing the car to operation in the presence of aggressive chemicals on the roads?

Referring to the official data on the model Renault Logan, it can be noted that there is a zinc layer on the body of this car, which corresponds in its parameters to the standards of the European automotive industry. However, some owners tend to doubt this aspect, since the first generation of the “Frenchman” sinned with the rapid appearance and spread of corrosion on the arches and lower edges of the doors.

So what's the real deal here?

As it turned out, the first generation of Renault Logan is spared the presence of galvanization on most body panels. In numerical terms, this share reaches 60%. This fact was confirmed in the cost of the car, because if there was a 100% zinc coating, the price could soar to a prohibitive value for the market segment.

In the second generation, the French solved the problem by coating up to 90% of the panels with a zinc layer.

Summing up

Now you know whether the body is galvanized or not. Renault Logan has reliable protection to withstand the onslaught of aggressive external environment. An excellent measure is a timely inspection of the body with immediate measures for the conservation of areas that are among the problematic ones. This event allows you to extend the life of the most expensive component of the car - its body.

On cars from the inexpensive segment, galvanized bodies are found, but this happens extremely rarely. The fact is that not every manufacturer can afford such expenses, because in today's crisis every penny counts. But the partial method of galvanic and cold coating is used by automakers quite often. We learn from the article whether the Renault Logan body is galvanized or not.

Difference in years of production

ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!

According to official data, both the Logan body and the Duster body are galvanized. On the contrary, unofficial sources assure that the protective coating from exposure through corrosion only some parts of the body are affected. This is its outer side, wings and a certain section of the front glass frame.

Yes, but this applies to Renault Logan, produced before 2007. More modern models have galvanized doors, a luggage cover and even a zinc-treated roof! Agree for budget car what Logan is is commendable.

And that is not all. For the purpose of additional protection against rust, the company's engineers use the technology of "sacrificial anodes", which involves the installation of special inserts in weak spots bodywork, such as door hinges. This is done in order to body parts rusted these very inserts.

The reason to think about the issue of galvanizing was a big problem caused by corrosion. The body of state employees Renault Logan and Duster literally ate rust after several years of operation. This mainly concerned cars produced in 2005-2006. The manufacturer then explained what happened with an unsuccessful choice of paintwork.

In fact, according to reliable sources, the culprits of the “weak” paintwork were the AvtoFramos employees themselves. They incorrectly applied a special mastic to the body, which ultimately had a negative effect on the paint.

Today, the control over the quality of work is carried out seriously. In the event of the problem described above, the owner is advised to urgently contact the Renault service, where the car body should be repainted for free.

Renault Logan and Duster resist the Russian cold well. If earlier the body often rotted, then after the modernization and the transition of quality control to another level, this problem is not observed at all. A test was even carried out, the results of which caused only approving remarks. On the Duster car, operated all year round and kept in the open sky, not a single hint of corrosion was found.

Does galvanization provide 100% protection?

It will be interesting to know that galvanizing itself, even complete, does not provide a 100% guarantee of corrosion protection. This fact has been repeatedly confirmed by tests and studies. In fact, the metal of a body coated with zinc will be protected from corrosion exactly until the moment when a mechanical impact is exerted on the surface.

Note. In other words, as soon as the car collides with any obstacle on the road, the corrosion process will inevitably begin in the place where the metal has come into contact with a foreign object.

Galvanization and its advantages

The most expensive and important component of the car is the body. The manufacturer knows this and tries to provide a reliable level of protection of the metal case from the effects of negative reactions.

Today, several technologies can be used, the purpose of which is to apply zinc to the body. Let's consider them.

1. Electroplating treatment.
2. Thermal coating.
3. Cold application option.

The first method of application is considered simplified, providing a relatively longer protection of the metal part of the frame. On the other hand, this method also has major drawbacks. Zinc, as mentioned above, is able to protect the coating, but only for a while. In addition, electroplating only protects smooth and even surfaces, and zinc becomes useless on edges and uneven areas.

The electroplating method is also the cheapest. It is often used in Asian countries, in the USA and Europe when processing cars of the budget segment.

Note. The electroplating method can be considered effective only if several simultaneous steps are combined to ensure safety from corrosive attack.

We must always remember that no matter how galvanized the body is, it requires constant diagnostics and timely anticorrosive treatment. If you neglect these rules, then soon the car will become impossible to operate. On the contrary, if you do everything right, the life of a car with OK can be extended to 10 years or more.

Many manufacturers, like Renault, only galvanize individual elements. The process itself regarding zinc processing is not simple. It requires expensive and special equipment, special qualifications of workers, etc. In addition, for the complete immersion of the body in zinc, special large-sized galvanic baths are needed.

The heat treatment method is considered to be more expensive and labor intensive than the electroplating method. But in this case it is achieved good result, giving a full guarantee for the metal component (10-30 years). The effectiveness of this technology is easy to prove, because a thick layer of zinc is applied to the body surface, which penetrates into the metal as a result of heat treatment.

Note. For the first time, this method was used in Volkswagen, where they still continue to process bodies using thermal exposure. With regard to the full galvanizing of the car body, then the pioneer in this case is considered to be Audi.

Cold working technology also gives good protection to the car. In the process of such application, finely dispersed zinc is necessarily used. This method is incredibly effective only with subsequent high-quality body painting.

You can learn more about the methods of galvanizing the body of Renault Logan and Duster from the video, photo materials and other articles on our website.

Consider some of the design features of the old (releases before 2014) Renault Logan car body. The aspects of its durability, comfort and passive safety.

Renault Logan - advantages and disadvantages

Despite the appearance in 2014 of a new generation of the model, the Renault Logan car in the same “clothing” will still prevail numerically for a long time. Therefore, interest in the model in the old body has not lost its relevance.

Comfort

The dimensions of the new Renault Logan are not quite common for a B-class car. With a fairly typical length of 4250 mm, its width is 1742 mm, which is more typical for class C or even C plus models. Additional 40-70 mm provide quite acceptable space in the cabin - on back seat three passengers are comfortably accommodated even in winter clothes.

As for the interior of the new car - what do you want from a cheap "budget" car? However, inexpensive plastic dashboard and synthetic fabric upholstery look quite decent.

For such a modest length of the passenger compartment, the doorways are surprisingly wide, and the door frames go to the edge of the roof. This design, coupled with low thresholds, contributes to quite sufficient ease of boarding and disembarking.

At a good level and soundproofing. An effective anti-noise mastic with which the machine is processed contributes to the reduction of external noise. The natural noise produced by it is minimized by precise fitting and quality welding of body parts.

Perhaps the only disadvantage that old car- not too spacious trunk.

Safety

Competent engineering and technological solutions adopted in the design of the body provide a high level of passive safety of the new car.

In the most dangerous frontal collision, its front part is easily crushed, extinguishing, at the same time, a significant share of the impact energy. For new cars with a longer length and longitudinal engine, this is easy to achieve. For machines with a transverse arrangement power unit and short engine compartment the task becomes much more difficult. However, the engineers of the Renault concern successfully coped with this problem. Variable hardness power elements front end designs provide the desired effect. In addition, this design leads to the fact that during a frontal impact, the engine and gearbox do not push into the passenger compartment, which is fraught with serious injuries to the legs of those sitting in front, but go down, partially under the floor of the passenger compartment.

In side collisions, the protection of the driver and passengers is provided by a carefully thought-out power scheme of the sidewalls and the door frame. Upon impact, the doors and pillars are not crushed exactly in his direction, but slightly down, thus removing the deformation from the most vulnerable part of the body.

The high rigidity of the vertical elements of the load-bearing frame of the body and its roof sufficiently protects the driver and passengers in the event of a car overturning.

Durability

The often encountered statement that the Renault Logan body is completely galvanized is fundamentally wrong. Such a solution is not often used even on cars of higher classes, since continuous galvanization not only makes the car heavier, but also significantly increases the cost of the car. Yes, this is often completely useless, since the rate of corrosion in different parts of the body varies significantly, especially in older cars.

Until 2007, the old Renault Logan had the following parts galvanized:

• front fenders;
• rear fenders;
• lower edge of the windshield frame.

Later, the new Renault Logan added to the list of galvanized elements:

• doors;
• trunk lid;
• roof panel.

In addition to these galvanized parts, the increase in anti-corrosion protection of the new Logan is achieved by using innovative technology, the so-called "sacrificial anodes". The bottom line is that in places most prone to rusting, special inserts are installed - zinc protectors that corrode instead of mating parts, prolonging their service life for a long time. The protectors have a much higher degree of oxidation, as a result of which, as it were, they “pull” these processes onto themselves. Such new elements are installed, for example, under the door hinges, hinges of the hood and trunk lid, in a number of other places.

The durability of Logan's body parts, both galvanized and others, is also ensured by the photophoretic priming technique. This technology not only ensures the penetration of soil into the most inaccessible places (hidden interfaces, welds, internal cavities), but also initiates an electrochemical process that significantly slows down the opposite process of corrosion.

Painting at the Renault plant is fully robotized, which eliminates the "human" factor. Unpainted fragments of surfaces or insufficient thickness of the paint layer are excluded, which also favorably affects durability.

The last stage of protection is the factory and additional pre-sale anti-corrosion treatment. For these purposes, effective mastics are used, which are also anti-noise.

maintainability

The simple forms of body parts from which Renault Logan is assembled allow for high-quality body repair even with fairly large deformations. And after removing minor damage, the part often does not require touch-up, since the factory paint does not peel off, but repeats the shape of the dent.
