Galvanized steel pipes are a lower cost alternative to stainless steel to achieve rust free protection for up to 30 years, while maintaining comparable strength with a durable surface coating. Galvanized pipes can be cut, machined or welded by common methods used for regular steel, but adequate ventilation should be used to avoid inhalation of fumes when heated.

Galvanized steel pipe types

Galvanized steel pipe include two kinds:

  1. Hot dipped galvanized steel pipe.
  2. Cold galvanized pipe, also called electric galvanized pipe.

Spangle in Galvanized Steel

With an aesthetic coating, spangle appears as a snowflake-like or flower-shaped coating. Spangle variations include zero spangle, minimized spangle, normal spangle, and large spangle.

Spangle in Galvanized Steel


There are many benefits to using galvanized steel pipes such as outstanding corrosion resistance, low cost compared to other materials such as PVC (polyvinyl chloride) or copper, high durability and strength, and efficient thermal transmission properties. Since they’re not susceptible to corrosion or rusting, these metal tubes can be used in both indoor and outdoor applications. They are also lightweight, easy to install, flexible enough to easily go around corners but strong enough to resist blows during earthquakes or extreme weather conditions.


While galvanized pipe is known for its use in construction, its rust-protective coating makes it a preferable metal option for automotive applications.  Galvanized steel is an excellent material for corrosion-resistant fasteners.

Galvanized steel pipe is used in numerous types of industrial applications, including:

  • General fabrication
  • Manufacturing
  • Construction
  • Automotive
  • Lighting columns
  • Walkways
  • Repairs
  • Frames
  • Trailers
  • And more

Can galvanized steel pipe be used for water?

Yes, galvanized steel pipe can also be used in water supply systems although they are mainly used for cold supply. Like other metal pipes, hot-dip galvanized steel water lines may release some chemicals or heavy metals into the air or water due to corrosion. While this doesn’t pose a big issue when it comes to cooking purposes, it still poses a risk.

Is galvanized steel pipe safe for drinking water?

This is a complicated question that depends on the type of galvanized steel pipes used, how they’re installed, and how long you’ve had these metal tubes. Since all types of hot-dip galvanized steel piping contain zinc (which can leach into water), it’s likely for these metal lines to release some chemicals or heavy metals into the water.

Can galvanized steel pipe be used for natural gas?

Yes. Hot-dip galvanized steel piping is the preferred choice for natural gas systems because it cannot corrode, rust, or expand in temperature which can lead to wasted energy. It’s also easy to install and lightweight enough to bend around corners without splitting or deforming (although this seems like an impossible task).

Common grades?

Many different grades of steel can be galvanized, cast steel, hot-rolled steel, cold-rolled steel, and even some grades of stainless steel all qualify for galvanization. In general, the presence of iron in any metal makes it a candidate for a protective zinc coating. The difference among galvanized steel grades typically lies in how they were coated.
