GALVANIZED PIPES
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
Galvanized steel pipe is an excellent choice for many applications and processing techniques. Some common applications for galvanized steel pipe include Plumbing, Construction, Railings or Handrails, Fencing, Hot and Cold Liquid Transportation, Exposed Environments, Marine Environments.
With the proper protection galvanized pipe can also be sawed, torched, or welded. Galvanized structural pipe is ideal for numerous types of applications where corrosion resistance is required.
