Hot dip galvanized steel is a steel covered in zinc coating to protect the steel from corrosion. In the galvanizing process, the steel is cleaned and dipped in a bath of molten zinc solution at temperature of approximately 450 degrees.

Liquid zinc sticks to the metal and when the metal is pulled out of bath the zinc gets hardened. As a result there is a really hard outer coating of zinc which protects the inner steel core from corrosion and other types of moisture.

• Barrier Protection

Barrier protection is the oldest and widely used method for protection against corrosion. It isolates the base metal from the environment. Just like paints, hot dip galvanizing coating provides barrier protection to steel. As long as the barrier is intact, there is no corrosion and the steel is protected. If the barrier gets breached, the corrosion starts.

Two most important properties of barrier protection are abrasion resistance and adhesion to base metal. The impervious and tightly bonded nature of zinc makes galvanizing a good barrier coating. Coating like paint which have pin holes can be penetrated by elements which causes rapid under film corrosion.

• Cathodic Protection

Cathodic protection is an effective way for protection against corrosion. It requires changing an element of corrosion circuit by introducing a new corrosion element which ensures that the base metal becomes cathodic element of the circuit.

In case of hot dip galvanizing zinc will either corrode or protect to protect the underlying base steel. The cathodic protection ensures that even if the coating gets damaged to the point bare exposed steel, no corrosion will start until the surrounding zinc gets consumed.

• Zinc Patina

Zinc patina protects zinc coating unlike cathodic and barrier protection which resist corrosion to steel. Zinc begins to corrode when exposed to atmosphere like all metals. Freshly galvanized steel can naturally wither when exposed to dry and wet cycles in the environment.

Fully developed zinc patina is passive and stable film that sticks to the zinc surface and is not soluble to water so it does not get washed off in rain or snow. Zinc patina gets corroded very slowly and protects galvanized coating underneath which brings down the corrosion rate of the steel in the same environment.

As the development of zinc patina takes place, galvanized coating turns in a matte grey color. Zinc patina formation is very important in long-lasting corrosion resistance of hot-dip galvanizing.

Hot dip galvanized coating is resistant to mechanical stress. The resistance is twenty times higher than resistance of PVC coatings and epoxy dust coatings and eight times higher than resistance of epoxy coatings.

One of the advantages of hot-dip galvanizing is there is no doubt about quality as you cannot apply zinc coating to an unclean steel surface while it is possible on the other hand when applying paint.

Thus, hot dip galvanizing is a far more lasting and better solution than paint to protect the corrosion of steel surfaces.

Hot dip galvanizing process refers to the process of coating the base metal with zinc by dipping the base metal into a bath of molten zinc so as to enhance the durability of the base metal and at the same time prevent it from corrosion. Now, at the time when the decision for galvanizing is finally made, it is to be made sure that the base metal should be appropriately fabricated for high quality galvanizing. There are a number of rules that are required to be followed for perfectly designing the base metal for galvanizing. These rules when applied provides the intended results and ensures maximum protection from corrosion. In an addition to this, following the rules properly also makes sure that the galvanizing personnel is safe, cost of coating is lowered and certainly produces the best quality galvanizing.

At the time of hot dip galvanizing, it is to be made a point that the designer, fabricator as well as the galvanizer should necessarily work together. The proper communication between these three ensures that a wide range of problems during the entire process getting eliminated. Here is a list of the few major steps to be taken in this regard.

• Removal of soil and grease from the base metal
• Pickling of the base metal to remove the rust from its surface
• Fluxing of the base metal for the removal of oxides for the prevention of oxidation prior to dipping into molten zinc
• Now, galvanizing is done where the base metal is dipped into a bath of molten zinc to form the coating of zinc
• Then comes the finishing step where the base metal is withdrawn from the bath and the excess zinc is removed by draining by vibrating and for the smaller pieces by centrifuging.
• Finally, inspection is done to check for any imperfections

Materials Suitable

Almost all of the ferrous materials are suitable for the purpose of hot dip galvanizing. The structural steel metals including the high strength low allow materials are hot dip galvanized after fabrication for obtaining the long lasting protection by the zinc coating.

Here is a list of materials that are suitable for hot dip galvanizing.

• Cast iron
• Cast steels
• Malleable iron
• Hot and cold rolled steels

Though most of the ferrous materials are suitable for being hot dip galvanized, the characteristics of the galvanized coating so formed is a function of the chemical composition of the material. A reaction between the steel and the molten zinc is the basis of hot dip galvanization which results in the formation of layers of alloy of zinc and iron.

This is to make sure that the drainage as well as the venting requirements are effectively met. Once the steel is in the staging area, it is handled with extreme care so that the transportation is done quite effectively through the initial process of cleaning. This concludes the process of preparation of steel for galvanizing.

Cleaning the Base Material

The next step cleaning which is one of the most vital part of the overall process of hot dip galvanization. This cleaning process begins with the complete dipping of the base material that is steel in a hot alkali solution for the removal of all organic compounds and dirt. The next step is the acid pickling process that helps in the removal of scale or rust. The ultimate step involved in the process of cleaning is fluxing which helps in the elimination of the surface oxides for the effective promotion of intermetallic development.

Hot Dip Galvanizing

As can be understood from the name, in this step the base material steel is submerged in a bath of molten zinc until the temperature reached is 840 degrees Fahrenheit. At this point of time, zinc reacts with the base material steel for the formation of zinc and iron intermetallic layers on all the surfaces completely leaving not even a minute part. Then it is taken out and cooled which concludes the process of hot dip galvanization.

Galvanizing is basically the process of adding a coating on any base metal for the purpose of increasing its strength, efficiency as well as durability. In most of the cases of galvanization, the base metal is steel and zinc is the metal with which the steel is coated. This coating of zinc on stainless steel readily enhances its strength and durability. This is exactly the reason as to why the process of galvanization is so popular. But it is to be kept in mind, that a trusted, reputed and reliable galvanizing service provider like Tanya Galvanizers should be necessarily chosen so as to get the best possible results in this regard.

Now, the process of galvanization is classified into two main types which are as listed below.

• Hot dip galvanizing
• Cold galvanized

These two processes of galvanization have the same ultimate motive of application of a coating to the base metal but there are some differences between the two process of galvanization. A detailed explanation of the difference between hot dip galvanization and cold galvanized are as discussed below.

Differences in Terms of Plating

In hot dip galvanization the base metal is dipped into a bath of molten zinc so that a layer of zinc is formed on the base metal where the zinc coat very strongly adheres to the base metal. This process helps in the prevention of the base metal from being corroded thereby enhancing its durability.

On the other hand, cold galvanizing where the zinc salt solution is plated on to the base metal by the process of electrolysis. This process does not involve any kinds of heating. This form of galvanization does not allow the zinc to adhere strongly to the base metal and a wet environment causes the coating to fall off very easily. Cold galvanizing is also referred to as plating.

Differences in Technical Terms

The base metal is first degreased and then followed up with a number of process of like pickling, dipping, drying, immersion in molten zinc & finally cooled in case of hot dip galvanization.

On the other hand, in case of cold galvanizing involves a process of electrolysis of a solution of zinc salt in which the zinc gets deposited on the base metal located at the anode during the process of electrolysis. The base metal so placed at anode during the process of electrolysis goes through the process of degreasing and picking prior to the process.

Differences in the Process of Treatment

Hot dip galvanization is actually a chemical treatment in which an where an electrochemical reaction takes place.

But in case of cold galvanization, a physical treatment takes place in which a layer of zinc just gets brushed on the base metal.

Differences in Function

The base metal is immersed into a bath of molten zinc which forms a uniform layer of zinc on the base metal that strongly adheres to the to its surface thereby enhancing the benefits of the galvanizing process since it resists corrosion, rusting etc. in a much better manner.

During the process of electrolysis in case of cold galvanizing, the zinc is deposited on the base metal at the anode during which is not at all uniform. As it is conducted in a wet environment, the coating layer of zinc falls off quite easily.

Differences in Emissions

Hot dip galvanizing involves much lesser emissions and the galvanized pollutants includes the parts of waste acid pickling mainly.

But the cold galvanized pollutants include parts of electroplating waste, waste acid pickling, liquid waste such as passivation.

Thus, it can be clearly understood that hot dip galvanizing is a much more appropriate and effective option as compared to cold galvanization.

Galvanization is a process in which the base metal is coated with some other material so as to increase the durability, strength as well as functionality of the base metal to a great extent. This is turn is of a great help in enhancing the overall usability of the product. For this reason, the process of galvanization is readily used.

What is Hot Dip Galvanization?

Hot dip galvanization process is the application of a protective coating of zinc on steel so as to increase the durability of steel thereby playing a vital role in the protection of steel from all kinds of corrosion. This is basically the most commonly used methods of galvanization of steel. This process involves submersion of steel which is the base metal in this regard into a bath of molten zinc. Now, since the process involves complete submersion of steel into molten zinc, the coverage is necessarily complete both inside as well as outside. Thus, even if the steel to be galvanized is hollow, the protection is complete thereby making the steel more durable in nature.

How the Process of Galvanization is Carried Out?

The most important part in the process of hot dip galvanization is the preparation of the surface of the steel to be galvanized. It is of immense importance to make sure that the steel to be hot dip galvanized should be completely clean so that the molten zinc is able to form a sound as well as complete metallurgical bond with steel. Now, the overall process of cleaning and preparation of the surface of steel involves the steps that are as listed below.

• Caustic Cleaning

The process of surface preparation of steel begins with the step of caustic cleaning. As can be understood from the name of the step, it involves the removal of a number of organic impurities such as dirt, grease and oil from the surface of the steel by a hot alkali solution. All the other unwanted substances like asphalt vinyl, epoxies or welding slag is cleaned by mechanical means.

• Pickling

In this step, scale and rust is removed from the surface of the steel with the help of hydrochloric acid in an appropriate temperature. This step is vital for the purpose of elimination of rust as well as scale from the surface of the steel to be hot dip galvanized.

• Rinsing

Once the process of chemical cleaning is wrapped up, the steel to be galvanized is then properly washed in water so that the transfer of acid residues to the following stages of galvanization is readily minimised.

• Fluxing

Fluxing is the ultimate step in the preparation of the surface of steel for the hot dip galvanizing process where all of the oxides are removed and further formation of oxides is prevented thereby playing a crucial role in the promotion of the bonding of the coating of zinc with the steel in the best possible manner.

Now, once the overall process of surface preparation of steel is complete, it is then submerged in a bath molten zinc of approximate temperature of 830 degrees Fahrenheit which contains about 98 percent pure zinc. Then the coated steel is taken out and properly cooled and the hot dip galvanized steel is appropriately ready for use. With this. The process of hot dip galvanization is completed.
