Galvanization involves coating steel, iron or aluminum with a layer of zinc. Although various methods can be used to apply the zinc layer, the most common method is hot-dipping, or fully submerging the metal in a bath of molten zinc. Hot-dipping is usually preferred over other methods because it produces a thicker, more durable zinc layer.
Galvanized materials have a range of uses, including pipes. Galvanized steel pipes are particularly popular for outdoor applications. Here are a few commonly asked questions about galvanized pipes.
How does galvanization protect pipes?
The zinc serves as a sacrificial layer. It will rust before the metal beneath it, keeping the integrity of the pipe intact for much longer than regular pipes. Furthermore, even if the zinc layer is scratched or damaged, it will still protect the metal beneath it.
Are galvanized pipes expensive?
Prices vary depending on your galvanized pipe supplier and the scope of your project. However, galvanized pipes are often more cost-effective that paint projects, particularly when you consider longevity and the need to often re-touch paint jobs.
How long will galvanized pipes last?
The thicker your zinc coating, the longer your pipe will last. The environment also plays a role in determining your pipe’s life span. If your pipes will be placed in highly corrosive conditions, they’ll often last 50 to 100 years.
