Hot-dip galvanizing is the most environmentally friendly process for preventing corrosion in steel and other materials.
Hot dip galvanizing is a process in which a Corrosion-Resistant Zinc Layer is formed by completely dipping the steel in a Zinc Alloy at approximately 450 Degrees Celsius. It is a metal anti-corrosion process that has been applied for more than 100 years. In recent years, the process has also continuously innovated and developed with the fast and wonderful progress and innovation in the industry.
Hot-dip galvanizing creates a very strong bond between the zinc and the steel, creating a coating that will last for generations. Hot Dipped Galvanized Steel structures are protected by a zinc coat, even in their most vulnerable areas. But it depends on the amount of zinc alloy. The strength of galvanized steel will increase as the zinc content increases.
Why Choose Hot-Dipped Galvanized Steel?
Galvanized steel has a strong protective coating of zinc with a metallic bond. This is what makes galvanizing for steel a corrosion protection solution aimed at long service life that is easily inspected and self-maintained. Hot dip galvanizing has gained fame and popularity because its life is more than general steels. Moreover, performance and quality are maintained at all times and require very little maintenance.

How Does its Process Work?
We discuss many aspects of hot-dip Galvanized Steel Coil. We cover its introduction and reason for using it. All this information will help the readers to make the decision to buy the best steel. We will discuss different other things that will be helpful for our clients.
But this paragraph is special for seekers of knowledge. Students will find useful information from here to complete the requirements of their assignment. We will explain the process behind galvanized steel. In upcoming paragraphs, we will return to general information that will be helpful for both clients and students.
Clean Steel
When the process of galvanizing starts, its total life depends on the first step. You need to clean the steel before putting it into zinc alloy. It should be free of grease, dirt, and scale before galvanizing.
Various processes remove this type of dust. The most common process is to first reduce it by using an alkaline or acidic solution in which the component is sink. After this product is washed in cold water so as not to contaminate the rest of the process.
Fluxing of Alloy
It is usually applied by immersion in a flux solution. It is usually about 30% zinc ammonium chloride at about 65-80°C. Alternatively, some galvanizing plants may operate using a flux blanket over the galvanizing bath. The fluxing process removes all remaining oxide residue on the surface, enabling the molten zinc to effectively bond with the steel.
Final Galvanizing Process
When pure iron or steel components are dipped in a hot alloy of zinc, the metallurgical reaction between iron and zinc forms a series of zinc-iron alloy layers. During this period the main thickness of the coating is established. After that, the reaction slows down and the thickness of the coating does not increase significantly.
Postal Treatments
Post-treatment of the galvanizing process may include quenching in water or air quenching. The quality of the galvanized coating is not affected by factors like temperature, humidity, or air quality within the galvanizing plant. They are essential for good quality paint for galvanized metal. But postal treatment is only required for the very peak areas where weather conditions remain too hard and change suddenly.
Applications of Hot-Dip
As we say above we will provide information that relates to clients’ and students’ needs. Now we will share peak knowledge on the usage of hot-dip galvanized steel. We are hopeful that this will help customers find solutions for products and students to achieve their results.
1. Electricity Generating Grids
In the construction of power stations for power generation, steel is an important construction material. People use galvanized steel for making platforms, equipment buildings, stairs, and handrails. Galvanized steel conveyor systems are common in coal-fired power stations in the area of fuel supply to main power generating plants. Cooling water, water reticulation and fire protection systems use large amounts of galvanized steel in the form of piping and its fittings.
2. Roads and Bridges Development
Governments of many countries now spend a large part of their budgets on improving infrastructure such as roads, highways and expressways, railways, mass rapid transportation systems, port terminals, and airport facilities. These projects use large amounts of exposed steel, and thus, hot-dip galvanizing is the preferred corrosion protection system.
3. Mobile phone signal-providing towers
Steel towers that are used to provide signals are difficult structures to maintain, considering. Their location is generally difficult to access as it is situated on hill slopes and top of mountains. For easy installation, these steel towers are joined with steel tubes in different sections and with steel angles of different sizes and lengths. Hot dip galvanized bolts, nuts, and washers are used for this purpose. These 3-legged signal towers are 100% hot-dip galvanized and duplex coated for long-term corrosion protection and aerial identification.
