Guidelines While Welding Galvanized Steel

Hot dip galvanizing process is being used to safeguard iron & steel from getting rusted for centuries. It is actually a zinc coating over steel. Similar to paint, it safeguards steel from rusting. This is achieved by forming a barrier between the environment and the steel. However, galvanizing does take a giant step when compared to pain. It offers electrochemical protection to steel. As zinc is found to be electrochemically reactive when compared to steel, the galvanizing coating can prevent steel from getting rusted. Therefore, galvanized steel is considered to be a much superior product when compared to steel being provided with other coating types on it. Even if the coating gets damaged in service or while handling, it safeguards the steel. We provide hot dip galvanizing services at an affordable price. For more details call: 91 8000842648

Galvanized product welding

Welding is done on galvanized steel similar to welding bare steel of similar composition. With some modification, similar welding process, travel speed, amps, volts, etc. could be used, if the switch is created from uncoated steel to that of galvanized steel. This is until zinc coating is found to be unusually thick. It is important to consider the importance of hot dip galvanizing.

Difference between welding uncoated steel and welding galvanized steel is due to low vaporization temperature resulting from zinc coating. It is at 900 F that zinc melts and vaporizes at 1650 F. With steel melting at 2750 F & welding arc temperature being 15000 – 20000 F, zinc close to the weld vaporizes. Zinc is just gone as weld pool freezes.

Why galvanizing is not done after welding?

The question why not galvanize after fabrication and avoid the problem. Steel products are galvanized always after fabrication since no practical way is present to restore galvanizing effectiveness after welding. It is routinely that galvanizing after fabrication needs to be performed very carefully. Fabrication is to be cleaned with acid, which again is to be neutralized. Then the fabrication is to be immersed in liquid zinc pot at 900 F. Great care is to be taken to ensure that when fabrication is lowered into zinc, it is dry. This is because, trapped water may flash to steam, thus exploding zinc everywhere. Zinc easily flows out and into every nook and corner for achieving complete coverage. It is quite tough if tubes are used for creating fabrication, as tubes are to be open on both its sides to allow proper flow of zinc. Trying to achieve uniform coverage even with the simplest fabrication could prove to be difficult.

Finally, the fabricated product is to be fit properly into the molten zinc pot, which again can be a tough challenge especially by having large structures. It is much easier to galvanize sheets, plates, structural shapes, wires and tubes, prior to creating them into products. This is because they have simple shapes, without any crannies or nooks, no place to trap water or any hidden cavities.

Reasons Why You Need To Use Galvanized Steel-Tanya Galvanizers

Reasons Why You Need To Use Galvanized Steel

There are innumerous benefits to be derived from using Galvanized steel. This particular element is regarded to be sustainable, honest and proven.

Reasons to choose Hot dip galvanizing services

There are numerous reasons to use galvanized steel, some of which are given below:

  • Honest: Since unique allow development takes place while immersing clean steel into molten zinc, coating becomes effectively part of steel. This element is sure to appear nice and beautiful for a long time.

  • Proven: Galvanized steel is said to share a very long history of more than 200 years. Several examples do exist in different environments about its impeccable performance. In 1944 was constructed a bridge in Dorset at Lydlinch for assisting supply flow during D-Day landings. Callender-Hamilton design was intended originally to serve as temporary bridge. However, this bridge is still in use! On carrying out an inspection in 1999 of the bridge by the Galvanizers Association, it was found to be in top new condition without having any rust signs on its members. The experts are of the opinion that the coating will remain maintenance free for over 100 years.

  • Tough: Galvanizing process is of unique nature. Zinc iron alloy layer series is formed thus offering abrasion resistant and tough coating. It means quick erection of the structures and less damage caused to the site.

  • Sustainable: Galvanizing does offer long term durability due to its low relative environmental burden with regards to energy along with various globally relevant impacts. Studies conducted have revealed high environmental and economic costs that are associated with steel structure requiring repeated maintenance painting. Again lack of attention towards maximum corrosion protection is likely to leave behind damaging economic legacy related to repeated maintenance costs. It is the local authorities who are found to bear the future maintenance costs of social housing projects. Again, galvanized steel being used for public infrastructure projects does lead towards lower maintenance budgets, as well as releasing public funds meant for various purposes.

  • Can provide complete coverage: According to the industry experts, steel gets dipped into molten zinc bath. This means protection can be offered to internal and external surfaces of steel component by hot dip galvanizing.

  • Self healing: With regards to steel, zinc tends to corrode, sacrificing itself towards safeguarding the steel. Therefore, such sacrificial protection is offered by hot dip galvanizing. Zinc based corrosion products are said to be deposited upon steel, thereby resealing it from atmosphere and to stop corrosion.

  • Quick: The process of steel being dipped in molten zinc tends to take few minutes. However, it is preparation of steel work does take a good amount of time. In practice, several other works gets processed within the same time. Hence, the typical time for turnaround is approximately 3 days. However, by arrangement, 24 hour turnaround can be offered by galvanizers.

The Importance Of Hot Dip Galvanizing- Tanya Galvanizers in Gujarat

The Importance Of Hot Dip Galvanizing

These days, there have emerged numerous companies that has been offering top quality hot dip galvanizing services at affordable rates to its clients. One should not compromise on the quality aspect for price. But before trying to avail such services, it will be first necessary to have a clear understanding why galvanizing is considered to be important and required in the first place. Only then can the best services be availed that can prove to be useful and worth the investment made.

About Galvanization

It is considered to be a process to apply protective zinc coating over metals like iron or steel for avoiding premature corrosion and rust. Galvanized steel’s proponents are known to us this method for repairing or to construct steel structures. For instance, they can benefit immensely from lower repair and maintenance costs associated with it due to its special properties.

Need for protection

Without provide adequate protection, it is quite natural for steel to rust quickly because of atmospheric conditions that it faces with time. Again, the degree of rust is likely to depend upon the environment in which the product is present. Rust is regarded to be iron oxide (which is typically red oxide). It is formed with the oxidation and reduction reaction of oxygen and iron, with the presence of air moisture or water.

Although there are present several protective methods to be followed like plastic coating or painting, these methods tend to have their own drawbacks. If damaged, the steel sections are likely to become rusty, thus causing the protective coating to fall away, thereby making such protection types to be unreliable and non-lasting (always require continued maintenance).

Why use hot dip galvanizing of earthing materials?

Hot dip galvanization according to the industry experts is considered to be a wonderful and time proven method to protect steel materials. All material surfaces with this type are dipped into and then coated with molten zinc completely.

Zinc is said to face slow corrosion, thus providing it with extended life as it safeguards the base metal. With zinc being alloyed to iron, there occurs cathodic protection. It does ensure that the smaller steel areas which are exposed due to damaged do not get compromised by rust. The small damaged areas unlike that of organic coatings do not require touch up. Cathodic protection is sure to last for a long time until there is present zinc layer.

Special care is to be taken if the project needs contact between brass or copper and any galvanized material. It is deemed so in humid or moist environment, since there occurs rapid corrosion of zinc. Water running from brass or copper surface may have sufficient dissolved copper within, thus causing corrosion quickly. In case, it applies to the specific situation, then it can be prevented by ensuring flow of water to copper or brass parts from galvanized materials.

Benefits of galvanizing of sub station structures

There are several benefits to be gained through galvanizing, some of which are given below:

  • Low long term cost and less maintenance
  • Lower cost when compared to stainless
  • Longer life expectancy
  • Coating performance and longevity reliable
  • Protection offered to smaller steel areas exposed due to damage
  • Outstanding resistance offered to mechanical damage
  • Zero lost time with surface inspection, preparation and painting
  • Other types of coating will not offer similar protection

Maintaining Galvanized Metal Structures-Tanya Galvanizers

Maintaining Galvanized Metal Structures

It could be that the person is interested to know how hot dip galvanized metal structures are to be maintained.

Tips to Protect Galvanized Structures

Given below are the tips that can prove to be useful to protect galvanized structures.

  • It will be necessary to avoid exposure of galvanized steel products for a long time in environments where pH level is above 12 and below 6. Outside pH 6-12 range, the coating is likely to suffer more corrosion than what is normal.

  • Direct contact of galvanized steel product is better avoided with dissimilar metals like copper and brass, especially in corrosive environments. If dissimilar metals need to be used for galvanizing of Cable trays, then make sure an insulator is present between the galvanized product and the dissimilar metal.

  • The galvanized products are not to be abraded clean constantly. Also abrasive washing of the galvanized product is to be avoided completely. One effective way by which steel is protected by galvanizing from corrosion is through the creation of insoluble zinc corrosion products called patina in thin barrier film on the galvanized steel’s outer surface is through exposure to atmosphere. The protective patina is likely to be washed away by abrasive cleaning and the barrier protection will have to be protected once again by the galvanized article, thus consuming more zinc in the process. Zinc will be consumed more quickly due to constant abrasive cleaning, thereby reducing the galvanized steel product’s life.

  • It is possible to clean galvanization of crash barriers by using alkaline based cleaners, water based emulsifier of 12 pH or even lower or some organic solvents. The area is to be then rinsed with fresh water and wiped clean using a soft cloth. The GAA or galvanizer is to be consulted if there are still present any concerns with regards to cleaning the product.

  • For those galvanizing products located in highly corrosive environment, for example, heavy industrial, coastal, etc., the product is recommended to be rinsed regularly using potable water. It should be performed under sheltered conditions (not getting exposed to sun or rain).

  • Also, it is important not to store the galvanized products for a long time in poorly ventilated and damp places. The storage location needs to be dry having proper ventilation.

  • In case the product’s galvanized coating is caused with any type of physical damage like coating getting chipped or fabricated after galvanizing is done, then the damaged area is to be repaired with accordance to AS/NZS 4680. It will be useful to contact the reputed and experienced companies offering galvanizing services in Vadodara.

Cleaning galvanized surfaces

Several ways and methods do exist to treat various types of marks or stains. But any galvanizing cleaning treatment is to be conservative initially and if situation demands can become aggressive. Again, if some type of scrubbing or mechanical abrasion is required, there is recommended tough plastic bristle brush. As discoloration may take place, steel bristle brushes should not be used.

Aesthetic issues might take place due to cleaning of zinc surfaces using mechanical methods. The cleaned areas may contrast with the adjacent untreated surfaces, thus taking a long time to weather for getting uniform in color. Hence, the cleaning method is to be tested first in inconspicuous area, if aesthetic affect is found to be appealing.

Can Galvanized steel be painted-Precautions to take

Can Galvanized Steel be Painted? Precautions to Take

According to the industry experts, galvanizing could present several challenges when undertaking painting operations. Life can be added to steel surfaces along with its electrochemical activity and surface chemistry with zinc coating. Thus, it results in conditions which lead to adhesion failures with regards to applied organic coatings. Successful painting can be achieved by recognizing the different surface conditions which are presented by weathered and new galvanizing. Effective cleaning operations are then employed for mitigating its effects. It is by choosing coating products which develop enduring and strong bond to galvanized surface that ultimate success is derived.

About Galvanizing

It is the term used for metallurgical process which applies zinc metal layer over steel surface for avoiding steel corrosion. During the reaction, zinc layer is found to sacrifice itself for protecting underlying steel substrate. The zinc during the electrochemical reaction functions as the anode, while steel represents the cathode. With adequate zinc being used, corrosion can be avoided to protect steel.

Galvanizing types

Zinc through HDG (hot dip galvanizing) process can be used for coating piping, structural steel along with other steel shapes. The process involves using of hot acid baths in combination to clean steel. It is to eliminate scale and rust followed by immersion and fluxing into molten pure zinc bath heated in range 820 – 860F. HDG achieves zinc thickness within the range of 2-8mils for steel varieties and dependent upon immersion time in bath. HDG thickness of range 20-30 mils is achieved with few reactive steels. Sheradizing and electroplating are the other methods used for applying zinc layer to steel.

Duration of protection provided to steel with zinc coating

Corrosion may take place with zinc. As exposed to atmosphere, chemical reaction begins with oxygen, carbon dioxide, moisture & soluble airborne salts such as sulfates and chlorides. Zinc corrosion rate depends upon environmental exposure and severity. According to reports, galvanized steel surface of zinc of 2 mils tend to develop just 5% rusting that too after around 35 years of getting exposure in the industry environment!

How galvanizing can be painted?

Replacing lost corrosion protection: Although atmospherically stabilized zinc corrosion rate is low, zinc layer’s thickness is reduced with time. Atmospheric exposure severity and original zinc thickness is likely to affect galvanizing life. With corrosion, zinc layer gets reduced and its capability to safeguard underlying steel substrate gets diminished, while galvanic protection provided by zinc is lost. Here, polymer overcoating application is to be considered for extending the structure life.

Using Duplex System for extending life of galvanizing

Situations may come where immediate overcoating of HDG will be necessary for extending the structure’s life beyond zinc layer’s longevity. Synergistic effect gets created to extend galvanizing life as new HDG is used to overcoat along with organic coating. The latter tends to act as a barrier by preventing moisture from penetrating, thus slowing down zinc layer corrosion. Moreover, life of galvanized coating is extended by factor from 1.4 – 2.7 times the total of lives that has been predicted for each layer of coating.

For enhancing appearance

HDG often is overcoated using organic coating, since metallic gray spangling’s natural appearance may be objectionable. This is to impart specific desired color through architectural rendering or to enhance its appearance. In such situations, adding of an overcoat is sure to extend the galvanized layer’s life.

Batch Galvanized Vs Pre-galvanized Products-Applications and benefits

Batch Galvanized Vs Pre-galvanized Products | Applications and benefits

There is a common misconception among many that any type of zinc coating is termed as galvanizing. However, the truth is there are present various processes through which application of zinc coating is possible. HDG or hot dip galvanizing tends to refer to those coatings which are created through immersion of steelwork into zinc in molten form. Two variations are present of HDG process, namely, Pre-galvanizing and Batch Galvanizing.

About Batch Hot Dip Galvanizing

It is a process that is generally used for coating completely fabricated articles. Chemical cleaning is involved of work before immersing in galvanizing bath, specified with EN ISO 1461. The process given below offers full coverage including hollow section internal surfaces without the presence of any uncoated area. Highest corrosion protection level is also offered with the formation of thick coating.

Pregalvanized Steel product

The alternative available will be to take specific product like tubes, wires or sheet and use an automated process to galvanize them.

Pregalvanized Steel Sheet

It is considered to be among the most used of all pregalvanized products, specified with EN 10346. The sheet is uncoiled to be passed through reducing atmosphere before it gets immersed for short time period in galvanizing bath. On withdrawing it from galvanizing bath, there is used a mechanical wiper or air knife for eliminating excess zinc, to produce excellent surface finish. However, the result derived is thin coating varying between 7 and 42 μm depending upon the grade and most products having typical coating thickness of about 20 μm. Once galvanizing is completed, the sheet gets recoiled before the stockholder. It is uncoiled and then cut down for sale to produce uncoated edges.

Pre-galvanized Steel Tubes

Using automated procedure to EN 10240, it is possible to galvanize tubes. Here, immersion times re much shorter and on withdrawal, the tube bore may be blown down by steam to provide adequate surface finish. Coating thickness could be high by about 45-55 μm, even though most of the produced products may have significant thinner coating of about 20 to 30 μm. The tubes can be cut again for resale purpose to size to create uncoated edges.

Pre-galvanized Wire

Wire strands, from practical view point may be coated just using automated process, specified with EN 10244-2. If wiping procedures are used, then there will be shorter immersion times to eliminate excess zinc present and to achieve smooth finish. Again, coating thickness could vary with strand diameter and grade. However, it will be typically around 20 to 30 μm. Although it is not possible to galvanize individual strands to EN-ISO 1461, for such processing mesh can be found suitable for achieving thicker galvanized coating.

Coating comparison

It is essential to understand that both pregalvanized and hot dip galvanizing coatings tend to come with different characteristics. Also, as coating weights get specified for the steel sheet, weights tend to include the sheet’s both sides to ensure that coating life becomes half for equivalent coating weight that is specified within EN 10346.

Protect Crash Barriers from Corrosion-Tanya Galvanizers

Protect Crash Barriers from Corrosion

Zinc is exploited globally for its uses and for its unique properties. Its predominant usage (50% to 60%) is for corrosion protection, mainly galvanizing. This means having steel coated using metallic zinc. This is to protect the metal from corrosion. It is regarded to be a highly reactive metal and still can support safeguarding steel from corrosion, when this metal in itself is regarded to be vulnerable and requires adequate protection. But with oxygen present in air reacting with zinc surface, creates impermeable and dense zinc oxide coating. Zinc surface is protected from future attack from this physical crash barriers.

Offering maximum protection

An item that is coated in zinc, like the motorway crash barrier, galvanized dustbin or the roadside lighting standard tends to lose quickly its silver shiny appearance to become dull grey, due to zinc oxide coating formation that is regarded to be natural ageing process. Zinc coating’s physical barrier as well as its surface oxide is what said to protect the steel. Interface present between steel and zinc is actually not a single metal directly one upon the other. A reaction is created by the galvanizing process among steel and zinc, where there is form an intermediate iron-zinc compound, which further offers corrosion barrier including an unbreakable bond among steel and zinc. From steel, zinc is said not to peel away, unlike that of paint.

Providing in numerous benefits

If galvanized steel surface gets broken or scratched, then the exposed steel region is sure to corrode, since the physical protective barrier has been lost. But with zinc being more reactive when compared to iron offers further defence, since iron and zinc forms electrolytic cell similar to that of the battery, where iron’s natural reactivity combined with its desire to get converted into rust is covered to favor the reactive zinc material. Hence, zinc is expected to oxidize a bit and the scratch present in zinc coating will be healed by zinc oxide product. Since the zinc coating area is big, when compared to the coating’s break area, zinc actual loss amount to protect the steel is quite small. Therefore, zinc can be termed to be the perfect protector.

To safeguard steel car bodies, zinc coating provides twelve years of assurance against corrosion, which in itself tends to speak in volumes. The point it, irrespective of the type of painting steel has been provided with, it is simply no match for zinc, when protection is concerned. The reason is because paint offers just the physical barrier, but not the much needed secondary defense, if coating gets broken. As a result, once paint surface gets broken, corrosion tends to advance rapidly within the paint left.

Uses of Crash Barries

Two major galvanizing classifications are present, namely, continuous galvanizing and general galvanizing. Zinc could be applied by electrolysis in continuous galvanizing process. But this process is known to be less used for providing protection. Moreover, the method is used for safeguarding bigger structures like bridges. However, the protection offered is considered to be not that good like the individual component galvanized during primary manufacture. This is because, the application and preparation is not well controlled at the construction site.

What Are The Reasons There Could Be Defects In Galvanizing-Tanya Galvanizers

What Are The Reasons There Could Be Defects In Galvanizing?

Some common defects may arise during hot dip galvanizing process. There are several reasons for the causes of such variations and defects to take place.

Galvanized Coatings: Some defects

  • Ungalvanized weld areas: The weld areas may have some coating misses which could be due to welding shag being present on the welds. The fabricator is required to remove the welding slag before it is delivered to the galvanizer.

  • Mottled or dull gray coatings: Thicker galvanized coatings will be generated by reactive steels which are dull when compared to standard coatings. Such coatings tend to have longer life due to their greater thickness. Moreover, their appearance is steel metallurgy’s function, which is beyond the galvanizer’s control.

  • Dark stains present adjacent to welds: Unsealed overlaps may witness preparation chemicals entering them or poor quality welds simply boil from connection during the galvanizing process. This will only cause coating misses and surface contamination during galvanizing. Moreover, anhydrous fluxing salts remaining within the connection are likely to absorb atmospheric moisture, while leaching onto adjacent galvanized surface. Such salt leaching will each eventually the equilibrium. It is necessary to clean wash the affected areas for removing those slight corrosive leachate.

  • Inclusions/Dross Pimples: During galvanizing process, dross is generated as zinc iron crystals or in the form in higher melting point when compared to metal in zinc bath. Galvanized coating experiences trapped dross which gives out that gritty or rough appearance to the coating. Dross inclusion presence in coatings will not be found to be detrimental to performance of the coating, since zinc dross resistance is identical, similar to that of galvanized coating.

  • Ash staining: During the galvanizing process, there is formation of zinc ash, since it is in zinc that the work gets immersed. The ash that is generated gets skimmed off the molten zinc surface before withdrawal of the work from galvanizing bath. At times, ash can be found to be trapped within the inaccessible areas, while sticking to the external part of the coating, when the bath is exited by the work. A light brown or dull surface stain is left by ash after removal. However, the galvanized coating performance is not affected in any manner.

  • White storage staining: Once galvanizing is completed, the items stacked or stored in poorly ventilated, wet conditions will become white bulky zinc hydroxide deposits upon the galvanized coating surface due to atmospheric moisture reaction.

  • General surface irregularities and striations: Lines thicker than adjacent galvanized coating and ridges may appear due to varying zinc reaction with steel surface. This is more due to the stress areas upon the steel surface or probably the welds presence or weld metal that is modified metallurgy into parent metal. It is regarded to be a common phenomenon faced with tube and pipe products. However, coating performance is not affected in any manner.

  • Bare patches: The uncoated areas of the galvanized work surface are because of inadequate pretreatment in pickling, degreasing, pre-fluxing and poor surface preparation. It is necessary to get the areas repaired by making use of recommend repair procedure or regalvanize the item, if defect is found of sufficient size.

  • Puddling, drainage spikes and runs: They are termed to be unavoidable defects in general item hot dip galvanizing process. They are acceptable unless the function assembly of the item is not affected or safety hazard present in service or handling.

The above are stated to be the few of the reasons for defects to appear in galvanizing and amazing solutions to it.

Recycling of Galvanized Metals-Tanya Galvanizers

Recycling of Galvanized Metals

Steel according to the industry experts is considered to be among the most recycled of all materials available in the world. Recycling of galvanized steel helps to reduce expenses tremendously, thus saving a good amount of money. At the same time, it also helps to save the environment. This is indeed a fabulous solution when compared to refining new steel and mining. It is possible to have galvanized steel along with zinc coating provided for rust protection to be recycled. If the desire is to have galvanized steel recycled, then it can be done by hiring a well established scrap dealer who will get the job done as planned.

It will be useful to check out the amount of money that can be derived from scrap steel. Online index such as Metal Prices can be used for finding out current high and low prices for steel. It will provide a clear idea of what is to be expected, when steel is taken for recycling purpose. The fact is prices tend to fluctuate. Hence, prices are to be monitored on a regular basis for few days for getting that broader picture.

Hiring process

It will be useful to compare the different providers in the region who can offer the very best hot dip galvanizing services. There are several companies who may be interested to purchase the steel pieces. Local business listings can be used for searching for honest and certified scrap dealers. Even the waste management office in the locality can be checked out to identify if there is present a listing or website exclusively for scrap dealers. It is very much necessary to hire the services of a steel recycler who has been in the domain for quite a long time and known for providing impeccable services. As steel recycling is found to be common, it is easy to come across several providers in the region.

Things to do

Once the steel recycling dealer is identified, they are to be called up to know the amount that they will pay up for the scrap steel. The dealer who pays the highest rate is to be selected and their location needs to be quite close. The reason is because, the expenses related to hauling heavy steel to the other part of the city is likely to be more and only will minimize the savings made from high rates offered.

The steel is to be then loaded onto the truck and get it delivered at the scrap dealer’s premises. Some dealers are found to accept materials only during specific business hours, while others may accept the same at any time. Prior to making the delivery, it will be useful to find out if the dealer requires special documentation for transporting the materials like photo identification or title for the scrap vehicle. Laws have been passed by many countries which require dealers to gain information about those selling scrap, due to increase in widespread metal theft. Hence, it will be useful to have necessary documents brought along and a check received for the scrap materials.

What Are The Different Types Of Galvanizing-Tanya Galvanizers

What Are The Different Types Of Galvanizing?

Galvanizing is termed to be among the most widely utilized methods to safeguard metal from corrosion. This method tends to involve applying zinc in thin coating to thick base metal, to help shield the same from surrounding environment. A good number of lamp posts and street signs can be found to have silver color upon them. This silver is stated to be actually zinc coating.

Why Galvanizing?

Having a metal galvanized provides it with anti-corrosion properties. Without using protective zinc coating, metal would be remain exposed to the different elements and oxidize as well as corrode quickly. As a matter of fact, galvanized steel can prove to be cost effective solution when compared to using materials like aluminum or austenitic stainless steel for preventing corrosion. Hot dip galvanizing services in Vadodara offered by the reputed providers can help the organization to stay ahead in competition.

Know the different galvanizing methods

Several processes are involved for galvanizing metal, which are given below:

    • Hot dip galvanizing: Like the name suggestions, this particular tends to involve the base metal getting dipped into molten zinc pool. Initially, the base metal is to be cleaned chemically, manually or probably both for assuring good quality bond that can be achieved between zinc coating and base metal. After getting cleaned, base metal gets fluxed for eliminating residual oxides present after completion of the cleaning process. base metal gets dipped into heated zinc liquid bath to form metallurgical bond. The benefit derived from this specific method is considered to be economical and can be quickly performed to complex shapes. But final coating is stated to be inconsistent and relative to the other processes of galvanizing.

    • Electro Galvanizing: This type is said not to make use of molten zinc bath. Rather, the process uses electrical current within an electrolyte solution for transferring the zinc ions into base metal. It involves the electrically reducing zinc ions that are positively charged into zinc metal that gets deposited onto positively charged material. also can be included grain refiners to ensure steel getting smooth zinc coating. This method is applied typically to sheet metal roll. The benefits to be derived from it are precise coating thickness and uniform coating. But the coating may be thinner than zinc coating that is achieved through hot dip galvanizing process, thus resulting in diminished corrosion protection.

Take a look at our blog for Difference Between Hot Dip Galvanizing And Electro-Galvanization

  • Pre-galvanizing: It is a method that is found to be quite similar to that of hot dip galvanizing. However, it is at a steel mill that it gets performed, typically on materials, which have already a particular shape. This method involves metal sheet being rolled through a cleaning process, which is similar to hot dip galvanizing procedure. Then, this metal is passed through pool of liquid hot zinc to be recoiled. A major benefit derived from this particular method is that steel sheet in large coils could be galvanized within a short span of time having more uniform coating, unlike that of hot dip galvanizing. However, the cons are that after pre-galvanized metal fabrication takes place, the uncoated, exposed areas become present. It effectively means, when long sheet coil is cut to small sizes, its edges where metal gets cut remains exposed.

Reputed providers like Galvanizers have their certified hot dip galvanizing plant from where they produce different types of galvanized products like cable trays, crash barrier, race ways, earthing strips, earthing materials, sub-station structures and much more.
