Recycling of Galvanized Metals

Posted on by

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?

Posted on by

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.

The Pros and Cons of Galvanized Steel

Posted on by

Steel is the most common material that is immensely used in the industrial sector for variety of applications. If steel is left out in open, or if it’s used on a continuous basis then it is bound to get affected by wear and tear and especially the effect of corrosion can result in its damage. Galvanization is the process by which a protective layer of zinc is applied on the steel based surfaces to prevent the process of rusting. Thus, Galvanized steel becomes strong and safe from the effect of corrosion. The hot dip galvanizing Services in Vadodara are very famous as they help in getting the best steel with galvanized coating. In hot dip galvanization process the steel surfaces are submerged in zinc solutions and that gives a long-lasting coating with supreme results. There are both pros as well as some cons of galvanized steel that you must know before availing such facility.

 

The Pros of Galvanized Steel

There are many advantages of getting the steel galvanized and they are listed as follows-

  • Durability- The galvanization process of steel makes it highly durable. Thus, its strength can be increased multiple times.

Galvanized Steel vs Stainless Steel-Tanya Galvanizers

Galvanized Steel vs. Stainless Steel

Posted on by

Steel is one such material whose importance cannot be underestimated in the industrial sector. It is used in variety of structures, equipment, processes and industrial settings. The two most famous types of steels are none other than galvanized steel and the stainless steel. Many people think that galvanized steel and stainless steel is the same thing because of their similar look but in reality they are different from each other. These two varieties of steel are different when it comes to their composition, strength and other features and one must know the distinction very clearly.

The difference between galvanized steel and stainless steel

There is no doubt that both galvanized steel as well as stainless steel are exceptionally good for industrial use but there are a lot of differences between the two options and they are highlighted as follows-

  • Composition – Galvanized steel is obtained by applying a zinc coating on the steel surface to protect it from corrosion and there are Galvanizing Services in Vadodara for obtaining high quality galvanized steel. Whereas the stainless steel is actually the steel alloy that contains at least 10.5% of chromium that helps in corrosion resistance.
  • Affordability – Galvanized steel is more affordable than stainless steel because in stainless steel two or more substances are usually embedded to get steel that result in higher costs. Whereas in galvanized steel the already existing steel is coated with the zinc layer that can be done by the processes like hot dip galvanization, spraying, painting etc. The Galvanizing Services in Vadodara is the best for obtaining any help in this domain.
  • Uses – Galvanized steel being less costly can be used for immense applications like construction projects, pipe based fittings, in fencing arrangements, roof installations, in making various industrial equipment, and for many other applications. Stainless steel is costly thus it can be mainly used for big projects where monuments, structures or buildings are to be built with its support.

Thus, there are a lot of fronts on which the galvanized and stainless steel differ from each other. Based on the customized needs the right one can be selected for various industrial applications.

The unimaginable benefits of galvanized steel for industrial components

There are many industrial and factory based components like cable trays, crash barriers, raceways, earthing strips, substation structures etc. that require galvanization services time and again. It is very important to get such components galvanized because it helps in increasing their life, strength and effectiveness level. The galvanization process creates an active layer of zinc on the steel items that prevents corrosion and thus helps them in becoming absolutely rust free.

The Galvanizing Services in Vadodara are trustworthy when it comes to the need of galvanizing any steel based materials. And another important point to note is that these services are very reasonably priced and thus the clients don’t have to face any sort of financial burden. Galvanization is the most effective way to ensure top notch finishing for substances made of steel and it also makes them scratch free.

Industrial / factory components which must be galvanized for better return on investment

Posted on by

Nobody can imagine the development of an economy without the progress of industrial sector. And when it actually comes to the industrial sector it is highly dependent on the various industrial and factory based components that ensure smooth functioning of the entire system. If these industrial components will not run smoothly then everything will come to a standstill and that is why it is absolutely necessary to take care of them, thus galvanization of industrial components is vital.

Why galvanization of industrial components is essential?

Galvanization is highly essential for the industrial and factory based components as it prevents them from the effect of rusting. In the 21st century almost all the smart enterprises opt for the process of galvanization for their industrial and factory based components. In this process usually a protective layer of zinc is applied like a coating to iron or steel surfaces and thereby the life of such components increases by manifolds and they are able to run smoothly for a longer duration without any troubles.

One of the most common methods of galvanization is hot dip galvanizing where these components are submerged in the molten zinc solution. Galvanization is one of the best processes for safeguarding the essential components and once it is done, very less maintenance is required for the components. It is a reliable and trusted method that can be done very fast and the components that are galvanized are very easy to inspect as well.

The galvanization of industrial components that a must are listed below: 

Here are some components that are highly used in the industrial sector and in factories and for them proper galvanization is required time and again –

  • Cable trays – Cable trays are highly used in the power and electrical sector and without them one cannot even think that the power supply sector can run with perfection. It is very important to look after the Galvanizing of Cable trays as with high end coating the corrosive substances would be unable to reach the underlying surface. The life of cable trays will enhance with the galvanization process and it will function like a new component for many years to come in future.
  • Crash barriers – Crash barriers are vital for road safety measures and as they remain in the open surroundings they are more prone to rust. Galvanizing services for Crash barriers are highly essential as otherwise it can become completely corroded. The process of galvanization will provide a supreme coating on the surface of crash barriers and its durability will increase to an unimaginable level.
  • Raceways – Raceways form physical pathways for the purposes of electrical wiring. Thus in the field of electronics it is a highly demanded component. Galvanizing of raceways will provide it a really long life and there will be much less maintenance required in the future. The tougher coating will ensure automatic protection from any sort of damages that may occur because of coming in contact with atmospheric substances.
  • Earthing strips – The use of earthing strips is in various industrial sectors like electrical industries, automobile industries, engineering sector etc. In order to maintain a really good life and quality level the process of Galvanizing of earthing strips is very crucial. It will make the earthing strips more sustainable and they would become much easy to maintain.

Many people think that galvanization is an extra burden on the pocket but in reality the truth is something else. It is not an expense but it is actually an investment. With galvanization process the life of all the industrial components multiply and when one will analyze it actually leads to long term savings. Thus it is very important to get the industrial/factory components galvanized so that they can function without any interruption.

Galvanizing of Earthing Strips are Vital

Posted on by

With technology reaching a zenith of success, people have been blessed with so many comforts through machineries and tech savvy products that now, the absence of any of them can make a large difference to them.  In case of the high end machineries, it is very important that it’s functioning takes place in a smooth way and this possible by taking minute care of every machinery, in a delicate manner.

Before we proceed for the Earthing material it is vital to know why do we need the Earthing strips.

Earthing or Grounding an object/tower means providing an electrical connection between that object/tower and mother earth. This electric connection is achieved by running an electrical wire/strip between the tower and an earth electrode. Earth electrode is a metal plate/pipe/sphere properly embedded at a depth in the earth.

Therefore the main objective of earthing is to provide an alternative path for the fault current to flow so that it does not endanger the user of damage the equipment.

A good earthing system should have the following features:

  • By blowing fuse it can protect the user from danger of electrical shock.
  • It should ensure that the conductive parts of the electrical appliances should not reach an alarming level of potential.
  • For successful dissipation of short circuit current it must provide a safe conducting path.
  • Preserves the voltage at any part of an electrical system at a known value to avoid passing of excessive current or voltage on the appliances or equipment.

And now it comes into the mind of everyone as to how efficiency as well as the durability of the electrical equipments can be increased by galvanization technique.

Galvanization is considered to be a coating process among zinc, steel and iron. It alloys with the base metal surface while having the metal immersed in the molten zinc bath. It is performed at temperature of about 840 degree Fahrenheit. Furthermore, galvanized steel is used widely in applications especially where there is required corrosion resistance without involving stainless steel cost. It is also considered superior with regards to life-cycle and cost. Crystallization patterning existing on the surface is what identifies it.

Therefore like most of the corrosion protection galvanizing of Earthing Strips tends to act as barrier between atmosphere and steel. Since steel is vulnerable to atmosphere, erosion takes place when exposed to air and water.

Here are few points of efficiency by galvanization:

  • Low cost and easily affordable: By zinc coating of the steel it becomes affordable to large scale business as well for household goods where the erosion is maintained and also protects the high end machinery within affordable budget to get damage.
  • Reliability: Galvanization helps the equipments to be more reliable, ductile and can withstand high voltage.
  • Adaptability: Galvanization provides an alternative path in the electrical system to minimize the dangerous effect in the electrical system which happens at the time of lighting and unintentional contact with high voltage lines.
  • Safety: Galvanized high end machinery has a high level of safety procedure saving human life from electrical shocks and even secure the high end machinery by providing a safe path of lighting and short circuit.

Earthing system can prevent the dangerous effects of electricity. And by using galvanized strips, the efficiency, durability and ductility of the electrical appliances could be maintained in a neat way.

The Environmental Impact Of Hot Dip Galvanizing - Tanya Galvanizers

The Environmental Impact Of Hot Dip Galvanizing

Posted on by

For producing building materials of any type does require energy inputs, materials, waste outputs and emission. The key towards sustainable development can be started to lower down the environmental impact upon producing a product. This is achieved through optimizing manufacturing. More objective measures and transparency have been pushed by specifiers, especially those committed towards sustainable development.

The fact is Hot Dip Galvanizing steel does come with several environmental benefits which can help to minimize the overall impact to the environment over the project’s life.

 

Abundant, Natural Materials

It is from two naturally found elements that are found in abundance like iron ore and zinc that Hot Dip Galvanizing steel is created from. The base metal is iron ore (steel), which is regarded to be the fourth most found element within the Earth’s crust. Hot Dip Galvanizing Coating comprises of about 98% of zinc is considered to be a healthy, natural metal. Zinc of over 5.8 million tons is being cycled naturally through the environment. This is done by rainfall, animal and plant life, as well as another natural phenomenon.

Zinc is also regarded to be essential to life. It is required by humans and even microorganisms to survive. It is equally crucial for growth since it plays a significant role in cell growth, division and wound healing. An important role is also played in the regular functioning like digestion, breathing, cognition and reproduction. Zinc, among all micronutrients, is said to have a very strong effect upon the immune system, thereby helping to fight infection and preventing diseases. It is also used in fertilizers for promoting growth and fortifying crops.

With zinc being found naturally in the environment and cycled throughout, using HDG steel is not likely to introduce any kind of harmful or disruptive elements to the overall eco-system.

Renewable Resources

Steel and zinc being both abundantly naturally found are infinitely recyclable. There is found no loss of chemical or physical properties. It effectively means instead of getting down-cycled into the other types of products or its uses, they can be repeatedly used as steel and zinc, without their integrity getting compromised. Hence, when taking into consideration HDG steel’s life cycle assessment, this can be termed to be a cradle to cradle product. This is because no ‘grave’ exists for steel or zinc.

The other wonderful benefit towards minimising the environmental impact is HDG steel’s 100% recyclability aspect. Its primary components, steel and zinc can be recycled, which is held crucial. Two recyclability measures do exist which will define ultimately the positive contribution made towards the environment, namely, reclamation rate and recycling rate.

  • Reclamation rate is said to measure the number of times, the product has been recycled at the end of the useful life.
  • Recycling content can be termed to be the volume of product which is produced from the different recycled sources.

The world’s most recycled material is steel, while zinc boasts of having high reclamation rate. Thus, it leads to having a higher recycling rate, since the reclaimed steel and zinc is put back to use once again. When HDG steel is concerned, structural steel’s recycling rate is much better, over 90%. Zinc’s recycling rate is much lower since not much zinc is available for reclamation purpose for creating a recycled product. It is its longevity and durability factor that allows it to be used for decades.

Quality Galvanizing Job work is done by the industry specialists, who can offer the very best, cost effective solutions.

Economic Advantage of Hot Dip Galvanizing

Posted on by

For the general public across the construction galvanizing industry and specifiers, sustainable development is very much crucial. It can be stated to be the environmental, economic and social commitment made towards development and growth. This is to meet the specific requirements of the present, but not at the cost of compromising the capability of the future generations in meeting their very own needs. An Economic factor often gets lost when emphasising sustainability factor. For achieving this true sustainability factor, there is to be created environmentally friendly structures. These also are to be responsible economically towards the future generations, helping them to thrive.

Better Economic Stability

With social pressure driving the sustainability movement, the specifiers are noticed to become much more analytical and invested when it comes to evaluating those materials that are used in the projects. Hence, the sustainability centres when considering the future, not only should regard the initial cost, but should develop appropriate long-term, life cost analysis. It is proper project cost evaluation throughout its life that can help to ensure better economic stability especially for the future generations to come.

How can Hot Dip Galvanized prove to be beneficial?

With Hot Dip Galvanized steel, Galvanizing of crash barriers, Galvanizing of earthing strips and Galvanizing of raceways becomes much easier and effective. It offers economic savings both initially as well as throughout the project’s life, thus freeing up a good amount of money to undertake new construction projects instead of focusing on costly maintenance work. Within the specifying community, the common perception is that Hot Dip Galvanized steel is much more cost prohibitive initially. But with regular improvements made in the process, combined with stable prices of zinc, galvanized steel has become competitive and less expensive when compared to other types of corrosion protection systems. Moreover, due to quick erection and turnaround, using Hot Dip Galvanized steel does offer during construction stage, wide range cost savings.

Even though, the initial cost is held crucial, trying to analyse the costs across the project life does offer the future generations with a much more comprehensive picture. LCC or life cycle cost does take into account the initial cost along with direct maintenance costs related to the structure’s life. It also includes money’s time value over the life of the project using NPV (net present value) along with NFV (net future value) calculations.

Since Hot Dip Galvanized steel is known offer maintenance-free corrosion protection for decades, the initial cost often is considered to be the life cycle, final cost. It can be really tough to evaluate LCC. Therefore for facilitating the analysis, LCCC (life cycle cost calculator) has been developed by the AGA. Calculations taken from the ASTM-A1068 standard practice is considered and the resulting data is used.

The Benefits of Online Calculator

Users are allowed by this online calculator to input the project’s parameters and to compare the life cycle and initial costs of Hot Dip Galvanizing to over thirty different corrosion protection systems, which are based upon the life cycle and initial costs of using duplex systems. These systems could be initially more expensive since payment is to be made up front for both the systems (paint and galvanizing). However, the initial investment is sure to provide much better returns over the project’s life, since it does require very less maintenance.

Overall, hot dip galvanizing steel does offer in numerous benefits to enjoy in the long run.

Difference Between Hot Dip Galvanizing And Electro-Galvanization

Difference Between Hot Dip Galvanizing And Electro-Galvanization

Galvanization is also known as galvanization is considered to be the technique to apply protective zinc coating for the iron or steel, for preventing rusting. Care is to be taken to the fullest extent in several services. This is actually to prevent the pipeline from getting rusted. Otherwise, it can prove to be hazardous to the personnel, may cause malfunction or damage of the instrument, equipment, etc. It is for this particular reason that piping is said to be galvanized.

Some of the commonly used techniques for the purpose of galvanization are stated to be electro-galvanizing and hot dip galvanizing.

Know the differences

If the plan is to order the same, then it is necessary to undertake proper and thorough research of the available materials in the market. This can help the person to be safe with his selection and ensure that the right and most appropriate products are purchased that meets specific needs and requirements of the business. Otherwise, it will be just merely waste of precious time and money. The professionals offering hot dip galvanizing services can help with the selection process.

Below are given some of the basic differences found between electro-galvanization and hot dipped galvanization. Also are provided the benefits offered by both over the other.

  • For hot dip galvanization, a very rigid cleaning process is followed, which is generally known as the 7 bath process. Cleaning is done in alkaline solution, pickling, water rinsing, fluxing. In case, of electro-galvanization, there is not followed stringent cleaning method.

  • Steel is said to be dipped in molten zinc bath @ 460 degree Celsius to achieve the coat for hot dip galvanization. But in the latter, steel is prepared in cathode in electrolytic cell, thus forming coating using electroplating process.

  • Hot dip galvanization produces on steel surface Fe-Zn alloy layer, leaving behind pure zinc coating on outer surface. This alloy is quite hard. Damage is not caused to the coating by the usual abrasion, even though some damage may take place to the pure soft zinc present at the top. Electro galvanization produces Zn layer on surface that is termed to be not continuous with that of steel metallurgically.

  • Electro-galvanization has very low life, ranging from several months to some years only. But, hot dip galvanization is known to have very high life averaging between 20 to 50 years.

  • Electro-galvanization comes with excellent finish. However, hot dip galvanization has dull, unpleasant finish.

  • The coating thickness of hot dip galvanization generally is about 80-100 µm. The coating thickness entirely depends upon the dipping duration. Also, it is affected by the steel’s roughness and composition. For electro-galvanization, coating thickness generally is about 10 to 12 µm. here, the coating thickness is determined upon the electrolyte temperature and current density.

  • Hot dip galvanization is said to have normal coat thickness of about 40% much more expensive when compared to electro-galvanizing. The latter has normal coat thickness that is much affordable. But, the cost is said to increase proportionately with higher coating thickness. Hence, it becomes expensive.

  • Hot dip galvanization is provided with non-uniform coating, while the other one with uniform coating.

  • Hot dip galvanization is suitable for all sizes, while electro-galvanization is suitable exclusively for smaller components.

To know more about the differences between hot dip galvanizing and electro-galvanization, it will be useful to take the help of the reputed companies offering top class hot dip galvanizing services.

Surface Preparation To Ensure Accurate Hot Dip Galvanizing - Tanya Galvanizers

Surface Preparation To Ensure Accurate Hot Dip Galvanizing

Posted on by

There are many who would like to know the type of kind of surface preparation of iron and steel is required before it is delivered at any hot dip galvanizing plant. For protective coatings, few of the specifications include Preparation for hot dip galvanizing before coating inspection and application requirements after and during coating application. Usually, for galvanizing, no special preparation is necessary. Speaking with the reputed hot dip galvanizing services can help the person to make a huge difference to the knowledge gained about the same.

Some Specifications

For the batch hot dip galvanizing, ASTM specifications are arranged differently. A153/A153M and ASTM A123/A123M are some of the commonly utilized specifications for Preparation for hot dip galvanizing. They cover all the inspection need of finished galvanized product.  ASTM A385/A385M, A384/A384M and A143/A143M are said to discuss on fabrication process for steel that are to be hot dip galvanized. They also can address few of the surface preparation recommendations before galvanizing.

The process

It is a simple process that batch hot dip galvanizers tend to involve for preparing iron and steel before galvanizing. Once inspection of steel is completed for ensuring presence of adequate drain holes and vent, it gets dipped into cleaning chemical series. The initial chemical is stated to be a degreasing bath to remove organic contaminant like grease, oil and dirt from metal. Pickling acid is the next type of chemical that is used to eliminate rust (oxides) and mill scale from steel. The final step involved prior to galvanizing is to dip the iron or steel into the flux bath. This is to avoid metal oxidization before entering galvanizing bath, as well as to help galvanizing reaction to develop hot dip galvanized coating.

There are not required any specific parameters for ASTM specifications to clean chemicals that are used within the galvanizing process. General concentration tends to make the chemicals quite effective and every galvanizer does optimize its cleaning chemicals, thus providing them with fabulous results to clean the iron or steel. This way, superior quality galvanized hot dip coating is achieved.

Few materials which cannot be removed by the cleaning chemicals

Several materials do make use of chemical chemicals before the galvanizing process. They may not be able to remove or face difficulty in removing. List of common materials:

  • Anti-splatter and weld splatter
  • Weld slag as well as welding flux residues
  • Burrs (may include those excessive rough edges derived from flame cutting)
  • Heavy or probably extremely adherent type of mill scale
  • Asphalt, vinyls, epoxies
  • Mill coatings like lacquers or varnishes present on several pipe types
  • Sand, other impurities present on castings
  • Crayon markers
  • Markers and oil based paints
  • Thick or heavy grease or wax deposits

Such materials are to be eliminated from the metal before it is delivered to galvanizing plant. There are present some commonly used standards to ensure abrasive blast cleaning, powertool cleaning and hand cleaning. These cleaning methods and the hot dip galvanizing services offered are considered to be effective enough to remove these materials. Usually, abrasive blasting is required on castings for removing sand including other impurities from casting process. Moreover, different types of products could be used on iron or steel that is considered to be compatible with hot dip galvanizing method for reducing the requirements for hand or power tool cleaning or blasting.
