Maintenance of Galvanized Steel-Tanya Galvanizers

Maintenance of Galvanized Steel

Some of the tips for maintaining and ca ring for hot-dip galvanized products are.

  • Do not expose your galvanized steel product to environments where pH is below 6 and above 12 for long hours. Outside pH 6-12 range, the galvanized coating is open to quick corrosion. 
  • Do not roughly clean your galvanized product and try avoiding rough washing of your galvanized product altogether. Galvanizing protects the steel from corrosion by developing a thin barrier film of insoluble zinc corrosion products (known as patina) on outer surface of galvanized steel through exposure to atmosphere. Frictional cleaning removes protective patina and galvanized articles have to build this barrier protection again which leads to consuming more zinc. Constant irritational cleaning will consume zinc more quickly and reduce the life of the product.
  • Galvanizing should be cleaned by using alkaline-based cleaners with pH of 12 or lower, water-based emulsifiers or organic solvents. The area should be rinsed with fresh water and wiped clean with a soft cloth.
  • Avoid direct contact of galvanized steel products with dissimilar metals, like copper and brass, in corrosive environments. In case of dissimilar metals being used together make sure that there is an insulator between dissimilar metal and galvanized products.
  • If a galvanizing product is situated in a highly corrosive environment like heavy, coastal, industrial, etc the product should be rinsed with potable water regularly under sheltered conditions.
  • Do not store a galvanized product for a long time in a damp and poorly ventilated condition. The storage location should be dry with effective ventilation.
  • In case of physical damage to the galvanized coating of the product, the damaged area should be repaired in accordance with AS/NZS 4680.

Cleaning Galvanized Steel 

While building or renovation, cement and mortar can be dropped on galvanized steel which is very difficult to remove once hardened. Remove large parts of deposit as close to surface as practicable, after that oxalic acid can be used to remove all the remnants from galvanized steel which should be followed with rinsing. Other acids are effective on mortar or cement, but they are very aggressive on zinc and are not recommended.

Paints, like graffiti, should be removed by thinners. If scraping is required, you can use plastic or wooden scrapers. In case the paint is wet or fresh, normal thinners can be used. Once the paint gets hardened, a non-alkaline stripper can be used. Rinsing is important to remove residues that cause discoloration later or encourage corrosion.

Mild stains can be removed by using common household ammonia cleaners and being sure to rinse the galvanized article with fresh water afterward.

Water draining of other adjacent steelwork which is rusting can flow on galvanized steel and cause brown stain. It can be treated by using commercial oxalic acid or proprietary solution which is generally used for descaling pots and pans. Rinsing with water is important to remove corrosive residues of cleaner.

In order to generally clean bulk contaminants like dirt and dust ordinary laundry soaps can be used. For stubborn or large areas, the use of low-pressure wash in collaboration with cleaning materials like car or truck wash or pure water are effective. Truck and car cleaners minimize corrosion on vehicles metallic parts and are suitable for use on galvanized steel. It is important that the steel is washed down with fresh water after cleaning.

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.

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.

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.

Galvanized Steel vs Stainless Steel-Tanya Galvanizers

Galvanized Steel vs. Stainless Steel

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.
