What is Galvanized Steel?

Galvanized steel is a material composed mainly of carbon and iron, after shaping, it will be coated with an outer layer of zinc. The steel will be dipped directly into the hot zinc solution or electrolyzed to create a durable outer shell, anti-wear, good anti-oxidation. In addition, they also help to increase the aesthetics and increase the hardness of the inner steel core.

The galvanized iron line has a much longer life than black steel of the same type and they are used a lot in outdoor works, road construction, coastal construction, where high technicality is required. The product has high hardness, relatively good durability and almost no warping or damage under the influence of external forces.

Galvanized steel has easy-to-find materials and low production methods, so the price of steel is quite cheap. During the construction process, if any errors are discovered, customers can easily check and quickly replace them.

The most popular types of galvanized steel today

On the market today, there are quite a few types of galvanized steel, but if divided according to the production process, they are divided into two main types: electro-galvanized steel and hot-dip galvanized steel.

What is hot dipped galvanized steel?

Hot-dip galvanized steel is actually a type of steel produced by the technology of coating the entire surface of the steel with molten zinc. Zinc will be melted at high temperature, then steel will be dipped directly into them. Each brand will require different coating thickness, from which the time to dip the steel is also different.

Before dipping into the zinc layer, the steel surface will be cleaned to make the adhesion process easier, reducing peeling when used. This modern hot-dip galvanizing technology is applied by many large iron and steel companies and corporations such as Hoa Phat, Viet Duc, Vinapipe, Pomina, etc.
