What is a Hot Dipped Galvanized Steel Coil?

Hot Dipped Galvanized Steel Coil is made of the coated carbon steel, and its coating is done by the zinc using the hot dipping method.

At the end of this process, on both sides of the steel coil, a zinc layer is bound tightly with the steel because of the bonding of the iron-zinc layer.This layer is made in diffusion, whereas with the molten zinc, the steel will remain in contact.

For many outdoor, industrial, or marine applications, Hot Dipped Galvanized Steel Coil is an essential element for their fabrication.

What is the Manufacturing Procedure of Hot Dipped Galvanized Steel Coil?

There are three basic steps used in the manufacturing of Hot Dipped Galvanized Steel Coil including:

Surface Preparation:

On reaching the galvanizing facility, the fabricated steel is put in a racking system or hung by the wire that is moved and lifted by using the overhead crane’s method. After this, steel has to pass through the three steps of cleansing such as:

• Degreasing

• Pickling

• Fluxing

Degreasing works by removing the oil, dirt, and other organic residues. At the same time, the pickling is used to remove iron oxide and scale. The final cleaning step is fluxing, which cleans the leftover oxides, and then its coating is done to prevent it from forming oxides. It’s the most crucial step because zinc would only react with a clean surface.

Galvanizing

After cleaning the surface, the steel is then dipped into the molten, having a temperature of 830° Fahrenheit and 98% of zinc. To escape from tubular shapes, The Prime Hot Dipped Galvanized Steel Coil has to be dipped inside the kettle at a specific angle. This will also help the zinc cover the entire piece of steel. While dropping in the kettle, the iron tends to react with the zinc for forming the intermetallic layers on the zinc-iron series and also for an outside layer of zinc.

Inspection

The last step done in manufacturing of Hot Dipped Galvanized Steel Coil is the coating’s inspection.

In this process, the accurate quality of the coating is determined by the visual inspection because the reaction of the coating can only be done on the clean parts of the surface so that it will leave the area uncoated in that case.

Also, gauze is used in its inspection to check the thickness of the coating done on it.

What are the Specifications of Hot Dipped Galvanized Steel Coil?

A considerable number of specifications are available for Hot Dipped Galvanized Steel Coil for producing the exceptional quality of the coating. At the same time, the most used specifications are ASTM specifications.

These are the three main ASTM specifications that are used for Hot Dipped Galvanized Steel Coil:

• ASTM A123/A123M: It is a Standard Specification used for the Zinc on coatings of Steel and iron products

• ASTM A153/A154 M: It is used for the Zinc Coating on Hardware and Iron

• ASTM A767/A767 M: It is also used for the Zinc Coating of Steel Bars in the process of reinforcement of concrete

What are the Properties of Hot Dipped Galvanized Steel Coil?

Hot Dipped Galvanized Steel Coil has a tightly bonded coating with a bonding strength of 3,600 PSI that is also corrosion resistant due to the layers of intermetallics, which are way more robust than other base steels.

The diffusion process allows the coating to grow perpendicularly. As a result, it gives the edges and corners of the steel’s flat surface a fine equalized thickness.

How is Powder Coating Done on the Hot Dipped Galvanized Steel Coil?

The process of powder coating on the Hot Dipped Galvanized Steel Coil is usually done in two steps such as:

• In its very first step, the steel coil has to be hot-dipped galvanized using a layer of zinc. That zinc layer will provide the steel a barrier and cathodic protection.

• Here comes the second step in which powder coating is applied on the Hot Dipped Galvanized Steel Coil part.

This last coating of metal powder helps prevent both galvanized and steel parts and gives it an attractive finishing.

What are the Reasons for using a Hot Dipped Galvanized Steel Coil?

Hot Dipped Galvanized Steel Coil can last for a longer time compared to other steel types. It also needs low maintenance than others.

The coating of zinc is simply a metallurgical structure that can fight mechanical damages and destructive environmental components.

The whole procedure of coating can be done in only a few minutes. It can be seen even with the naked eye.

What are the Applications of Hot Dipped Galvanized Steel Coil?

Here are some applications of Hot Dipped Galvanized Steel Coil:

Is It Secure to Use a Hot Dipped Galvanized Steel Coil with Pressure Treated Wood?

Pressure-treated wood is a wood type treated chemically to prevent it from decay, insect infestation, and rot.

This kind of wood is used in the outdoor constructions of wood, including building patios, picnic tables, swing sets, sheds, decks, fences, and other outdoor products similar to them.

The chemical treatment is doing a great job in preventing the wood from rotting. But, unfortunately, it also causes increasing corrosivity whenever it gets into contact with the metal products.

This is what makes the Hot Dipped Galvanized Steel Coil unsafe to use with the pressure-treated wood.

What are the Four Factors that Cause the Cracking of Hot Dipped Galvanized Steel Coil?

These are the four factors that cause the cracking of Hot Dipped Galvanized Steel Coil such as:

• Annealing temperature

• Processing lubrication

• Material thickness and mold clearance

• Control of inclusions and other defects

The annealing temperature is directly related to annealing. Therefore, if the temperature of annealing is low, then annealing must be insufficient, having refined grains with low elongation and higher strength.

Whereas if the annealing temperature is too high, then it will cause the considerable size of the grain, also the strength will decrease, and the tensile strength will be affected too.

The rough surface can affect the capacity of the oil storage. Also, the amount of oil is significant. Therefore, if the selected oil amount is low, it will affect lubrication which will not be enough for the stamping process.

If the selected amount of oil is too less, then the material will not be able to get enough lubrication which will cause the cracking of the material.

The die gap matching and thickness of materials is also an essential factor that can cause cracking of the material.

Infusion and body pressing in the process of stamping products are unfavorable. Furthermore, due to this elongation on the part of inclusion, there are high chances of cracking.

Is It Possible to Use a Hot Dipped Galvanized Steel Coil in Waterparks and Pools?

Waterparks and pools have to face the consistent attacks of corrosion because of treatment chemicals and moisture. Yet, every year their structures have been enjoyed by many people.

That’s why to ensure the safety of people, the quality of construction material matters a lot. A Hot Dipped Galvanized Steel Coil may have positive as well as negative effects on these aquatic facilities.

Hot Dipped Galvanized Steel Coil for Waterparks:

Hot Dipped Galvanized Steel Coil has been utilized in various projects related to waterparks all over the world. It is deployed basically to give support to the structure, handrails, stairways, and canopies.

However, the use of Hot Dipped Galvanized Steel Coil is not recommended for underwater applications.

What are the Effects of Different Water Applications on a Hot Dipped Galvanized Steel Coil?

There are large numbers of things that affect the working of a Hot Dipped Galvanized Steel Coil in water.

These things include mineral content, oxygen content, water climate, pH level, and water temperature. However, the durability and suitability depending on the water environment in which the steel coil is exposed.

Exposure to Pure Water:

Pure water is also known by the name of distilled water, and in this environment, there are high chances that a Hot Dipped Galvanized Steel Coil may be very corrosive.

The reason is the high oxygen present in it. That’s why its use in water applications is prohibited.

Exposure to Natural Fresh Water:

Natural freshwater includes all kinds of naturally occurring water except water from the sea, including canal waters, lakes, domestic water, groundwater, and river.

Galvanized steel is supposed to work very well in all-natural fresh types of water, having remarks of being soft and hot water.

Exposure to Seawater:

Galvanized steel can usually last for a period of almost 8 to 12 years in seawater. However, this durability varies with the temperature of the seawater and its content.

In warm seawater, which is closer to the equator, there is a possibility that it may rust earlier there.

In seawater, where the calcium and magnesium content in water is high, there is a possibility that Hot Dipped Galvanized Steel Coil may last there for longer than the standard lifespan.

Why and How White Rust Effects Hot Dipped Galvanized Steel Coil?

The zinc coating which is applied on the surface of Hot Dipped Galvanized Steel Coil is very reactive. It can efficiently react with atmospheric components, especially carbon dioxide, and then make stable oxides.

These oxides provide the Hot Dipped Galvanized Steel Coil its property of being corrosion resistant. The making of these oxides happens with the passage of time and is very progressive.

When it was first manufactured, it did not have a layer of oxides, which leads it to corrosion because of corrosion-causing agents.

In the case in which it has to be exposed to a high moisture content environment where oxygen is low, the zinc on the surface of the steel reacts with those elements.

Rather than the formation of stable oxides, it will form the unstable hydroxides of zinc.This chemical compound, which was unstable at that time, is known as white rust.

It gets eaten slowly with the coating of zinc and leaves the Hot Dipped Galvanized Steel Coil corrosive, leaving the galvanized steel exposed to further action of moisture other corrosive agents.

How Does Hot Dipped Galvanized Steel Coil Prevent Rust?

The hot-dip galvanizing process protects the Hot Dipped Galvanized Steel Coil from rust in many ways, including:

It develops a barrier to prevent the coil from corrosive materials by keeping the steel away from getting in contact with the steel.

The zinc coating works as a conciliatory anode. That’s why in the situation of the scratched coating, that scratched part of the steel coil will remain protected because of leftover zinc coating.

What is the Difference Between Galvanized and a Hot Dipped Galvanized Steel Coil?

Hot-dip galvanizing is one of the types of galvanizing. The main difference between hot-dip galvanizing and galvanizing is that the galvanized products end up with a sharp and smooth finishing.

On the other hand, Hot Dipped Galvanized Steel Coil has a rough surface finishing.Another difference between them is their coating process, such as coating of Galvanized Steel Coil by the layer of zinc formation, which protects it from corrosion.

While the coating of Hot Dipped Galvanized Steel Coil is done by the pure layer of zinc on the metal’s surface.

What are the Advantages of Hot Dipped Galvanized Steel Coil?

Prime Hot Dipped Galvanized Steel Coil is more durable as compared to other types of galvanized steel coils. Its coating is ten times thicker than the coating of an electro-galvanized steel coil.

Hot dipping forms an outer coating of pure zinc, and also, on the surface of the steel, it creates the iron-zinc alloy. That alloy can fight harmful substances.

It could be used to make pre-galvanized elements prior to assemblies, such as in wire, steel sheets, and tubing.

What are the Factors that Determines the Thickness of Hot Dipped Galvanized Steel Coil?

The coating thickness of a Hot Dipped Galvanized Steel Coil is not considered as the process but a function of the properties of steel.

It is not that process that determines the coating thickness in simpler terms. However, it is the property of the steel coil that instantly determines the possibility of the thickness of the coating.

The two essential factors that are used to determine the coating thickness are:

• Steel thickness

• Steel chemistry

What is the Effect of Steel Thickness on the Coating Thickness of Hot Dipped Galvanized Steel Coil?

During the process of Prime Hot Dipped Galvanized Steel Coil, zinc atoms in the bath of molten zinc diffuse and react into the atoms of irons to form the layer of iron and zinc, which will be intermetallic.

If the amount of iron for reacting with zinc will be higher than, it will be possible to develop a thick coating. Thicker steel products always contain higher iron concentrations.

So, naturally, they help to make the coating of Hot Dipped Galvanized Steel Coil thicker for the process of galvanization.

What is the Effect of Steel Chemistry on the Coating Thickness of Hot Dipped Galvanized Steel Coil?

Other than iron, there are supposed to be many different components that take part in the composition of steel, including phosphorus, silicon, carbon, and manganese.

For the galvanization process, phosphorus and silicon are considered essential materials. They work by promoting the bonding between the atoms of zinc and iron.

That’s why the product having a higher concentration of phosphorus and silicon can be used to develop the thicker coating of Hot Dipped Galvanized Steel Coil.

What is the Role of an Accumulator in a Hot Dipped Galvanized Steel Coil?

Accumulators are used to giving the space between the static steel and a continuous strip that passes from the furnace sections.

When the old feed coil gets replaced with the new one and their welding is done, attach the strips.The accumulator present on the entry point uncoils it for providing the continuous strip.

At the same time, the accumulator present at the exit is used to coil them up. This process has controlling features that are similar to the continuous annealing features used in its process, and its significant features are:

• Temperature of Strip

• A withdrawal rate of bath

• Immersion time of bath

• The cooling rate of steel
