Galvanized pipe

Galvanizing refers to the rust prevention method of laying metal zinc on the surface of iron or steel. Zinc is a highly corrosion resistant metal that insulates iron from oxygen and water, preventing the chemical reactions needed for rust. Because zinc has higher metal activity than iron, even if the zinc plated is damaged, zinc can still prevent rust in an electrochemical way with sacrificial protection. The main methods of galvanizing are hot dip galvanizing (HDG), electric galvanizing (EG) and cold galvanizing.

The main use of galvanizing is to prevent metal surface corrosion and oxidation. As a result, it is widely used in many different fields and industries, including:

Construction: Galvanized steel is widely used in the construction industry, such as building frames, roofs and walls. This is because galvanized steel has corrosion resistance and durability, which can extend the service life of the building.

Automotive industry: Galvanized steel is widely used in the automotive manufacturing industry, such as the manufacture of body and chassis. This is because galvanized steel can prevent the corrosion and oxidation of metal parts of the car, thereby extending the service life of the car.

Electrical industry: Cable tubes and cable jackets are usually made of galvanized steel pipes. This is because galvanized steel pipe has corrosion resistance and durability, and can be used in different environments for a long time.

Agriculture and aquaculture: Galvanized steel wire mesh and galvanized steel pipe are widely used in the agriculture and aquaculture industry, such as for fences, poultry houses and livestock houses. This is because galvanized steel wire mesh and galvanized steel pipe can prevent rust and corrosion, thereby extending the service life.

Machinery industry: Galvanized steel plates and galvanized steel pipes are widely used in the machinery manufacturing industry, such as the manufacture of mechanical parts and pipes. This is because galvanized steel plates and galvanized steel pipes have good anti-corrosion properties, which can extend the service life of mechanical equipment.
