Differences Between Hot-Dipped Galvanization & Pre-Galvanizing

Differences Between Hot-Dipped Galvanization & Pre-Galvanizing

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

Differences Between Hot-Dipped Galvanization & 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.

This surety of protection ensures a consistent honesty of with the usage of galvanized steel. 

 

Reliability of Galvanized Steel

Galvanizing of steel is a relatively controlled process. This makes the coating a consistent, process. It is because of this reason galvanizing steel is most reliable when it comes to corrosion protection. It is mainly because galvanizing is a metallurgical process that creates a metallurgical bonding rather than chemical or mechanical bonding making the zinc and steels a single structure. This ensures a thorough reliability with galvanized steel.  

Complete Coverage of Galvanized Steel

Galvanizing creates a metallurgical bond between steel and zinc, forming a coating that will last for generations.  This provides superior strength besides superior coverage, so that galvanized steel structures remain protected, even in their most vulnerable areas. This ensures that the structure is protected from inside out even in case of exposure to extreme corrosive condition, providing complete coverage with the usage of galvanized steel on any structure.

Predictability of Galvanized Steel

Galvanized coating on steel showcases a predictable protection against corrosion weather in a linear fashion. The thicknesses of the coating are measurable and offer life spans that can be relied on and forecasted easily.

Triple Protection of Galvanized Steel

The usage of galvanized steel ensures triple protection with its usage in the following ways:

  • Physical Barrier: A galvanized coating provides a physical barrier which is metallurgically bonded, and prevents the underlying steel from being exposed to atmospheric conditions.
  • Sacrificial Protection: A galvanized coating will corrode preferentially and slowly highlighting cathodic protection. It is because scratches on galvanized steel do not require repair work, and in case areas do become exposed to humidity and other corrosive elements, the galvanized coating will corrode preferentially and at a slower rate than the underlying steel.
  • Prevention of sideways creep: In the unusual event that a galvanized coating is locally compromised and bare steel is exposed, the zinc coating will limit damage and prevent a form of corrosion known as sideways creep, which in turn will protect the steel by slowing down the overall corrosion process.

This highlights the triple approach to protection with the usage of galvanized steel. 

Toughness of Galvanized Steel

Galvanizing has an abrasion resistance up to ten times better than organic paint coatings. The hot dip process is unique, producing a coating which is bonded metallurgical to the steel.  As a result, galvanized steel has superior resistance to mechanical damage during handling, storage, transport and erection. This unique metallurgical bonding ensures compact toughness to the galvanizing steel making it in uniquely applicable for all possible requirements.

The galvanization process is an assembling interaction where zinc covering is applied to steel or iron to offer insurance and forestall rusting. A few electrifying cycles are accessible, yet the most usually offered and utilized strategy is hot-plunge arousing. 

Galvanized steel is among the most famous steel types due to its all-inclusive toughness, having the strength and formability of steel in addition to the consumption insurance of the zinc-iron covering. The zinc secures the base metal by going about as a boundary to destructive components. The conciliatory idea of the covering brings about a durable and top-notch steel item. 

The galvanized steel carries out these following steps: 

  1. The steel is cleaned in a degreasing arrangement 
  2. After the cleaning, the steel dipped in salt by being brought down into a tank of weakened hot sulfuric acidic liquid. 
  3. The steel is then fluxed in a fluid arrangement 
  4. After the transition, the steel is excited through submersion in a tank of liquid zinc 
  5. A while later, the steel is assessed for consistency, and a total covering

Advantages of galvanized steel:

Low introductory expense: Contrasted with most treated prepares. Likewise, galvanized steel is promptly ready to utilize when conveyed. It doesn’t need extra planning of the surface, reviews, painting/coatings, and so forth, saving organizations more expenses on their end. 

Longer life: With galvanization, a piece of industrial steel is required to last over 50 years in normal conditions and can last more than 20 years with profound water openness. There is no support necessary. The expanded toughness of the steel’s done item additionally builds the item’s unwavering quality.

Rust resistance: The iron components in steel are inconceivably inclined to rust; however, the expansion of zinc goes about as a defensive cradle between the steel and any moisture or oxygen. Galvanized steel is highly defensive, including sharp corners and breaks that couldn’t be secured with different coatings, making it impervious to harm.

Importance of Galvanized steel: 

Full protection for damaged areas:  Galvanized coatings erodes, especially to steel, giving cathodic or sacrificial security to little areas of steel uncovered through harm. In contrast to natural coatings, little harmed regions need no final detail. 

Complete security: Every piece of a galvanized article is ensured to get protection, even breaks, sharp corners, and unavailable areas. No covering applied to construction or creation after fulfillment can give a similar assurance. 

The simplicity of investigation: Galvanized coatings are evaluated promptly by the eye, and basic non-destructive thickness testing techniques can be utilized. The galvanizing cycle is to such an extent that if coatings seem sound and persistent, they are sound and continuous.

Inspection of the Hot Dipped Galvanizing Process

Inspection of the Hot Dipped Galvanizing Process

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
  • There should not be any irregularities 
  • No areas should be uncoated
  • Presence of any kinds of lighter or darker grey spots 

All the points mentioned above should be carefully inspected to make sure that the end product of hot dipped galvanization process are perfect in all aspects and are ideally suited for the intended purpose of use.
