What is galvanized steel

Galvanized steel is a material that is coated with an outer layer of zinc to protect the product from the effects of the surrounding environment such as temperature, humidity, air,... Thereby, limiting the possibility of rust , anti-oxidation and corrosion to increase strength and life span of coils.

Methods of galvanizing steel

Currently, there are 3 most commonly used galvanizing methods: cold galvanizing, hot -dipping galvanizing and electro galvanizing.

Cold galvanizing method

Cold galvanizing is a method of coating a layer of liquid zinc on the surface of the product at room temperature and then putting it through a cold galvanizing process. Here, the mill uses compressed air to blow a liquid solution to form a beam of zinc particles that shoots onto the metal surface. In the solution, there are additives to help the coating adhere firmly to the metal surface and harden in a short time. Cold galvanizing technology helps to improve the corrosion resistance of metal, so it is the best solution for galvanizing metal materials on site.

The galvanized steel melting point typically ranges from °C to °C, depending on the specific composition of the alloy

Hot-dip galvanizing method

Hot-dip galvanizing is the most popular coating technology today, capable of effectively protecting coils from the effects of the environment. This process starts from dipping the product into a molten solution to form a strong, non-flaking base and a smooth, highly aesthetic product surface.

Electrolytic galvanizing method

Electrolytic galvanizing is a method of electrocoating that forms a thin layer of metal on the surface of a coil for the purpose of preventing metal corrosion, increasing electrical conductivity, size and hardness. In fact, the electrolytic galvanizing method is used for steel products such as water pipes, railways, outdoor equipment, bearing equipment, machine parts,...

Learn about standard galvanizing process

There are 3 methods of galvanizing steel, but hot-dip galvanizing is still the most commonly used method in Vietnamese factories with the following standard implementation process:

• Step 1: Metal surface treatment

Steel made from iron ore or recycled steel also contains many impurities, dirt and oil that reduce the ability to adhere to the coating layer. Therefore, the material needs to be soaked in the degreasing solution for 10 - 15 minutes and transferred to a solution of hydrogen chloride concentration of 8 - 15% to remove rust.

The density of galvanized steel varies depending on its composition and coating thickness

• Step 2: Embed Soldering flux

After the steel is cleaned, it is dipped into the flux for about 3 - 20 seconds at normal temperature to completely remove the oxide and iron ions on the surface of the product. This is also the step that creates a coating that protects the steel from oxidation.

• Step 3: Hot dipped galvanized

Steel will be completely immersed in the galvanizing bath at the melting temperature (454 - 465 degrees Celsius) to create a layer of zinc coating on the surface. After completing the hot dipping process, performing slag scraping on the surface combined with vibration to remove excess zinc, the product will be coated with a layer of chromate to protect the surface comprehensively.

• Step 4: Cool down and check quality

In order for the surface of the galvanized steel to be bright and beautiful, the product is cooled by an overflow bath. Experts observe and calculate the thickness of the coating by using specialized gauges to ensure that the finished product meets the specifications and requirements of the customer.

Top reasons why you must galvanized steel
