What is Hot Dipped Galvanized Steel?

Hot Dipped Galvanized Steel

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 Dipped Galvanized Steel

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
