What is galvanized? and its uses

Since the beginning of human life, metals have been used in many parts of human daily life due to their many characteristics. Iron is known as the most widely used element used in the manufacture of many products. The rapid oxidation of this black metal against oxygen has caused limitations in its various applications. Accordingly, metals such as iron and steel are coated with a thin layer of zinc metal, which is called the final galvanized product. Therefore, galvanized iron will be extremely resistant to rust and corrosion. Also, since the rapid absorption of oxygen by steel will cause corrosion and decomposition of this type of metal, it is necessary to cover it with zinc metal before use.

In general, several different methods are used to create various coatings to protect various metals against environmental factors, especially oxygen. Painting with anti-color is perhaps the simplest and easiest way to prevent oxidation of metals such as iron. In the terminology, this method is called cold galvanizing, which takes a long time to perform and must be done under certain conditions. It also has less resistance and strength compared to hot galvanized.

But the galvanization of metal parts has received much attention as a basic and cost-effective solution in recent years. Because, in addition to the simplicity of the technique and its reasonable price, by creating an excellent coating, it increases the resistance and stability of metal parts. Creating a layer of zinc metal on the surface of commonly used metals also improves their efficiency. Since the zinc element shows great stability and durability against oxidation, it is the best option for galvanizing all kinds of metals.

Galvanizing of metal parts or sheets should be done in several stages. Accordingly, firstly, the iron or steel piece should be completely cleaned and cleaned of any dirt and grease. In the second step, the metal piece must be thoroughly washed with acid or a suitable auxiliary solution. At the end, the desired metal is immersed in the molten composition prepared from zinc metal, which has a temperature of about 460 degrees Celsius. After the specified time, remove the metal and after it cools completely, it must be reacted with oxygen and then with carbon, so that a resistant layer is created on the surface of the metal. Then the quality of the final product should be checked.

Immersing iron metal in a large volume of molten zinc, in order to coat iron to prevent corrosion and rust, is called hot dip galvanizing. Hot galvanizing technique can be done in a short time and using simple equipment at low cost. The coating that is placed on metals with this method has an extraordinary adhesion. Also, this coating will increase the resistance of iron and steel against friction.    

Therefore, this technique is the most effective and widely used method to prevent corrosion of industrial products. Compared to other methods, the hot-dip galvanizing method has a low cost, which has made it attract the attention of producers and consumers in various sectors of the industry. Galvanized pipe, galvanized sheet and galvanized iron are among the most widely used products, which are used in many industries. The formation of the metal, the thickness of the coating and the amount of resistance that this coating provides are determined depending on the application of the product.

Characteristics of galvanized metals

Resistance and stability against oxidation, rust and corrosion is the most important feature that galvanized metals have. This characteristic has made metals such as iron and steel, which have a strong tendency to react with oxygen, to be protected and used in various fields. Also, galvanizing iron, steel and other metals increases their lifespan and efficiency. For example, if galvanized iron, galvanized sheet or galvanized pipe is used in the construction of industrial equipment, their life will increase by 20-30 years. If these equipments are not covered, they can be used for only a few years. Considering the change in weather conditions due to seasonal changes and direct sunlight, galvanizing commonly used metals is an economical and cost-effective solution. Because creating a protective coating on all kinds of metal products, in addition to increasing the life, reduces the consumption of precious metals in the construction of various structures.

Of course, note that the appropriate reactivity of metals with molten zinc will produce a durable and resistant product, and the cost of the technique and equipment used in the production of these products is much more appropriate than other methods. Also, the cost of maintenance and repair of galvanized metal products is affordable. In general, it can be said that using equipment coated with zinc metal is a long-term investment. Another unique feature of coated iron is its hardness against damage and impact, which may be inflicted on them in different situations. Also, changes caused by various factors that may occur on the surface of galvanized coatings can be seen with the eye. Therefore, there is no need to perform complex, long and expensive tests.

Galvanized uses

Due to the many applications that metals have in many parts of human life, wherever you look, you will notice their essential and special role. Therefore, according to the contents explained in the previous sections, the use of galvanized equipment with zinc metal will be much more compared to uncoated and coated products. In the construction of small and large structures, metals such as iron and steel are used, so if you want these metals to have better performance and last longer, they should be galvanized using molten metal.

As you know, the raw materials that make up most of the construction equipment are iron and coated steel. Coated steel and iron are used in the construction of roofs of houses, halls, hospitals, factories and many other possibilities. In the preparation and construction of industrial and commercial sheds, coated iron structures are used to strengthen its body. Also, coated metals are used in the construction of ready-made condos.

In addition, small galvanized structures are used in the manufacture of electronic equipment such as mobile phone parts, computer parts and audio and video equipment. Also, most of the products used in homes such as refrigerators, washing machines and dishwashers are made of steel or galvanized iron. It is used to prepare all kinds of pipes, industrial signs, water tanks and even kitchen utensils. Also, galvanized sheet, galvanized pipe, and galvanized iron are used in the construction of all transportation equipment, because these equipments have great stability and durability. In car production, galvanized steel and iron are used to make the body and roof shock-absorbing. Therefore, one of the most effective techniques for preserving iron and steel structures from rusting and destruction is the use of galvanizing method.

 

Galvanized sheet is widely used in industries such as construction (for roofs and walls), automobiles (making body parts), and household appliances (washing machines and refrigerators) due to its resistance to corrosion and rust. It is also used in the agricultural industry and the production of industrial equipment.

The difference in galvanized sheets in different factories is caused by various factors, including the type of galvanizing process, the quality of raw materials (such as base steel), the thickness of the zinc coating layer, as well as the production standards of each factory. Some factories use more advanced methods such as continuous galvanization, which can lead to a more uniform and resistant coating. As a result, the quality, durability, and final price of sheets may vary from factory to factory.
