How Galvanized Zinc Coating Enhances the Longevity of Steel Structures

Posted on December 10, 2024 by Galvanizers

Steel is a vital material in construction and industrial applications, prized for its strength and versatility. However, steel’s susceptibility to corrosion poses a significant challenge. This is where galvanized zinc coating comes into play as an essential solution to enhance the durability and longevity of steel structures. Applying a protective zinc layer ensures that steel withstands harsh environmental conditions, extending its life and minimizing maintenance costs.

What is Galvanized Zinc Coating?

Galvanized zinc coating is the process of applying a layer of zinc to steel or iron surfaces through techniques such as hot-dip galvanizing or electro-galvanizing. As more reactive than steel, zinc acts as a sacrificial layer, protecting the base material from corrosion. When exposed to moisture and oxygen, zinc forms a stable zinc oxide layer, which further reacts with carbon dioxide to create zinc carbonate. This natural barrier shields the steel from oxidation, ensuring structural integrity.

The Science Behind Galvanized Zinc Coating

The effectiveness of zinc coating lies in its ability to provide both physical and electrochemical protection:

Barrier Protection:
The zinc layer acts as a physical barrier, preventing moisture and oxygen from contacting the steel surface. This reduces the chances of rust formation.
Cathodic Protection:
Even if the zinc coating gets scratched or damaged, it protects the exposed steel through cathodic action. Zinc is more electrochemically reactive than steel, meaning it corrodes first, sparing the steel beneath.
Self-Healing Properties:
Galvanized zinc coatings have self-healing abilities at small scratches or abrasions. The zinc ions migrate to damaged areas, filling gaps and preventing further corrosion.

Differences Between Hot-Dipped Galvanization & Pre-Galvanizing

Posted on August 22, 2022 by Galvanizers

Galvanizing is one of the widely used methods for protecting metals from corrosion. It involves applying a thin zinc coating to a thicker base metal like iron metal. The process helps to shield the metal from the surrounding environment. When a metal undergoes galvanization, it does not experience any corrosion. However, without the zinc coating, the metal remains exposed to the elements and potentially oxidizes and corrodes faster. There are several ways of galvanizing metals, including hot-dipped galvanization and pre-galvanizing.

Hot-Dipped Galvanization vs. Pre-Galvanizing: What Are They?

As the name suggests, in hot-dipped galvanization, experts dip the steel in hot, molten zinc. When the zinc coats the steel, a metallurgical reaction occurs between the iron component of the steel and the hot zinc. The reaction known as the diffusion process occurs when the coating collects perpendicular to every surface, creating a uniform thickness.

When the expert removes the steel from the zinc bath, it reacts with the oxygen in the air to form zinc oxide. It then reacts with carbon dioxide and forms the final protective coating of zinc carbonate. With multi-layered zinc coating and iron-zinc alloy, the steel becomes corrosion-resistant.

Pre-galvanizing, also called mill galvanizing, is another galvanizing process close to ho-dipped galvanizing. However, this process occurs at the very first stage of production. The process takes place at steel mills that have a specific shape. Pre-galvanizing involves a few steps of hot-dip galvanizing, like cleaning the surface, hot zinc bathing, and recoiling.

Key Differences Between Hot-Dipped Galvanizing and Pre-Galvanizing

Application Comparison

Hot-dipped galvanization is an economical choice that you can execute on simple and complex shapes. Experts use it on objects fabricated beforehand and yet not galvanized. The hot-dipped galvanization plays the last step.

On the other hand, a metal requires undergoing pre-galvanizing at the first production stage. It mainly occurs at the mill and later undergoes cutting into size and fabrication.

Coating Comparison

Since the galvanizing process involves the application of a protective coating for the steel and metals, it is essential to consider the coating finish of the two methods of manufacturing galvanized steel.

Coating Thickness

Although both methods result in uniform thickness, the hot-dipped galvanization produces a thicker layer of protection than the other method.

Coating Continually

Hot-dipped galvanizing requires dipping the entire steel and other metals into the molten vat of zinc. The galvanized steel comes with a continuous coating over the surface. On the other hand, pre-galvanizing requires performing before cutting the sheets into perfect sizes and pieces; therefore, the cut edges do not undergo any coating.

Coating Formability

Since the process of pre-galvanizing undergoes at the mills, any coating applied after cutting the metals does not damage the layer. On the other hand, coating formability applied on hot-dipped galvanized steel is not advisable, as it might damage the protective coating of the products.

Coating Appearance

The hot-dipped galvanization forms a bright finish for the galvanized steel, which might or might not be uniform. On the other hand, the pre-galvanizing process produces a uniform bright finish for the coating.

There are numerous differences between hot-dipped and pre-galvanizing processes. Understanding the differences helps in choosing suitable methods and products for different projects.

How Effective and Durable is Hot Dip Galvanization

Posted on January 24, 2022 by Galvanizers

The process of galvanization is extremely crucial when it comes to businesses dealing with metal industry. The main reason being galvanization protects the metal from all natural elements increasing the longevity of the metal. Over the years through successful testing, application and research it has been discovered that hot dip galvanization is the most successful in protecting metals for longer period of time, than any other galvanization.

Let’s take a look at what hot dip galvanization is, and how effective and durable it is!

What is Hot Dip Galvanization?

Hot-dip galvanizing process is one of the most used application of galvanizing process. This process highlights coating a steel or iron object by submerging it into a bath of molten zinc. The bath of molten zinc showcases temperatures around 840°F (449°C). Once removed from the bath, the zinc coating on the iron or steel’s exterior reacts with oxygen in the atmosphere to form (ZnO) Zinc oxide. This Zinc oxide further reacts with carbon dioxide in the atmosphere to form a more compact protective layer known as (ZnCO3) Zinc carbonate. This Zinc carbonate reflects a dull grayish film, which is relatively stable and adheres tightly to the surface of the steel or iron. This results in the hot-dip galvanizing process to create a chemical balance, which ensures that the zinc is chemically bonded to the underlying metal and becomes part of the steel or metal that is being protected through the hot dip galvanizing process.

It is because of this reason Hot Dip Galvanization comes with many benefit, some of which are:

Application level benefits of Hot Dip Galvanization

It is a chemical bonding process and hence is un-reactive to regular corrosion process like salt water and rainfall
The use of hot dip process is generally applied to metal that will be exposed to natural element. And can be used for any size of metal.
Easily lasts up to 10 years – but there are historical data evidences suggesting Hot dip galvanization if performed with highest accuracy has been seen to deliver protection and longevity between 34 to 170 years for steel.
Hot dip galvanization is developed from chemical bonding process and hence is more resistant to corrosion.
The coating thickness of zinc is extremely high with uneven rough finish making it absolutely perfect handle even the worst of environment conditions
Surface layer is much thicker and rougher after the hot dip galvanization is done creating a larger surface tension against corrosion and hence allows the metal to last a longer period of time.

These benefits clearly showcases that hot dip Galvanizing is absolutely ideal to protect steel and other metals against elemental challenge that cause corrosion. Further the chemical bonding structure allows it to stand un-reactive clearly indicating the lost lasting durability that hot dip galvanization have over other galvanization processes.

Hot dip galvanizing is the process of application of a zinc coating to steel and iron. The process involves dipping of both unfabricated as well as fabricated pieces of steel, or iron into a bath of molten zinc at about 840 degrees Fahrenheit. Galvanization is done to enhance the ability of the base metal that is iron or steel to last for a longer duration of time without getting corroded or rusted. It is precisely where the importance of galvanizing lies.

Now, before the hot dipped galvanizing process a lot of steps are carried out to make sure that the entire process is carried out in a smooth and uninterrupted manner. In addition to this, utmost care is taken during the entire process to ensure that the intended results are obtained. The final step in the process of galvanization is inspection. Inspection of hot dipped galvanizing process refers to process of checking of the end product after the completion of the galvanizing process. The inspection of hot dip galvanizing process primarily focuses on the following two points.

The thickness of zinc coating on the base metal

The thickness of the coating determines the time frame of protection. Usually, the thicker is the coating of zinc, the longer is the expected life span of the base metal. Here are a few important things to consider.

Local coating thickness – It is the mean value of the zinc coating that is obtained from the specified number of measurements within an area of reference
Mean coating thickness – It refers to the average value of the local thicknesses on the different base metal pieces in the control sample

The appearance of the zinc coating on the base metal

The appearance after the hot dipped galvanization process refers to the visual inspection that checks for any sharp drops or points or any kind of irregularities. Here are the essential points to consider while inspecting the appearance of the zinc coating.

While inspecting visually, the coating of zinc must be free from any sharp points or drops

Difference Between Hot Dip Galvanizing and Boronizing

Posted on December 23, 2020 by Galvanizers

Hot dip galvanizing and boronizing are two different processes that involves coating of a base metal or alloy to enhance its life to a significant extent. Both the process forms a protective surface layer on the chosen base metal or alloy but each of the processes are completely different from each other. To learn about the difference between these two processes, let us delve a bit deeper into each process.

Hot Dip Galvanizing

Hot dip galvanizing is a process in which the base metal usually steel is dipped into a bath of molten zinc at high temperatures of about 450 degrees Celsius or 840 degrees Fahrenheit. Before dipping, the base metal or steel is cleaned in a caustic solution for removal of dirt and then passed through an acidic solution for removing flakes of iron oxide. The base metal is further cleaned with the help of a chemical cleaning agent like ammonium chloride so that the bonding of the base metal with zinc can be better.

Boronizing

Boronizing, on the other hand, is process of surface hardening of steel. It is a thermo chemical process for hardening the surface of the base metal usually steel. In this process, boron is added to the base metal or alloy where the atoms of boron are diffused into the surface of the base metal.

Difference in Functionality

Now, we are clear with the differences between the two processes. Next, we would be learning about the functional differences or the beneficial difference between hot dip galvanizing and boronizing.

Hot dip galvanization of steel helps in the improvement of the corrosion resistance capacity of steel of aby other base metal used. But on the other hand, boronizing case hardens the base metal, thereby providing even higher or superior corrosion resistance.
Boronizing plays a vital role prevention of wear and tear of the base metal, thereby making sure that the base metal becomes highly durable in nature. Reduced wear and tear provide the base metal with great capacity to withstand any external elements without any kind of compromise in the functionality of the base metal so boronized.
Hot dip galvanization only helps in the improvement of the corrosion resistance capacity of the base metal. But boronizing not only case hardens the surface of the base metal but also plays a significant role in improving the temperature stability along with several other mechanical properties of the base metal.
