Galvanized Steel Pipe

Galvanized steel pipe is galvanized on the inner and outer surfaces of steel pipes to prevent corrosion of the surrounding environment and increase the service life.
Product Description

Galvanized steel pipe is galvanized on the inner and outer surfaces of steel pipes to prevent corrosion of the surrounding environment and increase the service life. Galvanized pipe can be galvanized by seamless steel pipe or welded steel pipe, and different ways of galvanizing also have different effects on the service life of steel pipe. Galvanized pipes are widely used. The natural gas pipelines in our daily life are galvanized welded pipes. Galvanized pipes are also used in heating and greenhouse construction. Some shelf pipes used in building construction are also galvanized pipes for corrosion prevention.

Benefits of Galvanized Steel Pipe

Coated in zinc, galvanized steel pipes are protected from oxidation and rust, which ultimately prevents deterioration of the pipe. They are a great option when you need to protect your steel pipes from a corrosive environment. The protective quality of galvanized pipe is created through a hot-dipping process, where the zinc then provides a protective layer that will rust away before any of the steel is affected. In terms of durability, a galvanized steel pipe can last well over 100 years, depending on the amount of corrosion exposure.

Galvanized steel pipe maintains a wide range of benefits, suitable for use in highly corrosive environments. The semi-smooth, zinc finish of galvanized steel pipe provides a layer of protection that is not seen in other types of protective materials. The galvanized coating process protects the underlying steel from encountering corrosive elements that could deteriorate the steel and ultimately weaken its structural integrity. Main advantages of galvanized structural pipe include:

Protects against corrosion and rust

Increased structural longevity

Overall enhanced reliability

Affordable protection

Easy to inspect

Less repairs

Rugged toughness

Easier to maintain than standard painted pipes

Protected by advanced ASTM standardization

Common Applications for Galvanized Pipe

Galvanized steel pipe is an excellent choice for many applications and processing techniques. Some common applications for galvanized steel pipe include:



Hot and cold liquid transportation


Exposed environments

Marine environments

Railings or Handrails

Fence Posts and Fencing 

With the proper protection galvanized pipe can also be sawed, torched, or welded. Galvanized steel pipe is ideal for numerous types of applications where corrosion resistance is required.
