Galvanized steel is simply steel coated with zinc. After going through a process called galvanizing, in which steel is coated with zinc and a normal steel becomes a galvanized steel. This process is performed to avoid steel from rust and corrosion.

Galvanized steel has thousands of industrial applications, especially marine
products. They are commonly used in marine applications because in that case the pipe fittings are subject to tough and wet conditions. It is not a new concept, in fact, it is being used from early times. Till 1850, over ten million tons of zinc was used to protect steel. There is a misconception about the galvanized steel.
Many people think that galvanized is a better product, but it is expensive and increases the overall cost. In fact, galvanized steel becomes less expensive when combined with its long life span. Galvanized steel studs cost almost half the price as compared to wooden studs that are most commonly used in buildings. Galvanized pipes are not used for underground lines. It is relatively better to use for hot water lines, however, it also works good for cold water lines. Avoid using galvanized pipe fittings for gas supply lines as natural gas can cause the zinc to come off and cause blockages in the system.
Galvanized pipe fittings generally comes in size ranging from diameter of 1/8" to 20". These pipes are great value for money. No doubt galvanized steel pipes have various advantages, however, it has disadvantages also. One disadvantage is that the zinc coating can hide problems and defects beneath the coating which would otherwise be visible. And there are few more.
The important thing to remember is that whatever you choose, choose smartly. There is nothing on this planet that has only advantages, But there are things that have more advantages than disadvantages which makes them relatively better choice.
