Galvanized Steel

Wanhetong Steel has its own factory and has been deeply involved in the steel industry for more than ten years. Galvanized steel refers to ordinary carbon construction steel that has been galvanized to prevent corrosion and rust, thereby extending the service life of the steel. Galvanized steel is divided into two main methods: electrogalvanizing and hot-dip galvanizing.

Classification of galvanized steel

‌Hot-dip galvanized steel pipe‌: Hot-dip galvanized steel pipe forms an alloy layer through the reaction of molten metal and iron matrix. It has the advantages of uniform coating, strong adhesion, long service life, and strong corrosion resistance.

‌Cold-dip galvanized pipe‌: Cold-dip galvanized pipe adopts electrogalvanizing, with less galvanizing and poor corrosion resistance. It has been eliminated and is no longer used for important purposes such as water and gas pipes.

Application fields of galvanized steel

Galvanized steel is widely used in construction, machinery, coal mining, chemical industry, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery and other fields. For example, hot-dip galvanized steel pipes are widely used in fire protection, electric power and highways, while cold-dip galvanized pipes are mainly used for corrosion protection of some small equipment and components.

What are the advantages and disadvantages of galvanized steel?

‌Advantages‌:

‌Strong corrosion resistance‌: The galvanized layer can effectively prevent steel from corrosion and rust, and extend its service life.

‌Widely used‌: Suitable for various industrial fields, such as construction, machinery, chemical industry, etc.

‌

Disadvantages‌:

‌Cold-dip galvanized pipes have poor corrosion resistance‌: Due to the small amount of galvanizing, the corrosion resistance is not as good as that of hot-dip galvanized pipes‌.

Production process and welding technology

When welding galvanized steel plates, it is necessary to strictly control the welding process parameters, and use reasonable electrode materials and current methods to ensure welding quality and corrosion resistance. The multi-pulse current method can improve the strength and corrosion resistance of the weld.
