Galvanized steel pipe has the feather of corrosion and rust resistance. But it also has several types. According to the manufacturing technology, it is divided into hot dip galvanized steel pipe, electro galvanized steel pipe, pre galvanized steel pipe and galvannealed galvanized steel pipe. According to the coating zinc thickness, it also divided into Z50g, Z75g, Z275g etc.
Hot-dip galvanization is the most common method of galvanizing steel pipes. They are feathered with high-quality and long-lasting performance, which widely used into outdoor and industrial locations such as bridges, power plants, and water treatment facilities. Electro galvanized steel pipe adopts electric current to add zinc onto the steel surface, which leads to thinner and less durable than hot-dip galvanized one. Electro-galvanized steel pipes are usually used in indoor settings and non-critical applications where cost and aesthetics are more important than durability.

Uses of galvanized steel pipe include energy, construction, automotive, marine and offshore industries, telecommunication, agriculture and general fabrication.
Galvanized steel pipe has a large number of applications in the field of construction, mainly used in building structures and reinforced concrete formwork.
Galvanized steel pipe also has important applications in shipbuilding. It is mainly used to build the main structure of the ship, such as the hull, deck, bow, stern and other parts.
Widely used in oil and gas extraction, transportation and processing. It is used in the manufacture of oil well pipes, pipelines, drilling pipes and other petroleum equipment.
Galvanized steel pipe is widely used to manufacture a variety of mechanical equipment and parts, such as automobiles, ships, airplanes and construction machinery etc.
