This plumbing pipe is coated with zinc. It is pretty thick and also heavy. Grey or silver is going to be the exterior look of this pipe. House and building with modern construction are not commonly using this pipe anymore. But you will find the galvanized pipe in houses that were built between the 1930s and 1980s.

The zinc can be broken down eventually. It affects the pipe to get rusted internally. As the result, the water pressure can be reduced and the water lines get clogged.

Copper pipe

This pipe began the debut in homes circa the 1930s. But actually, it got common in the house that was built on the 1960s till today. Compared to steel pipe, copper pipe is thinner. Oxidation will change the original copper color to green or dark brown after times.

Copper is good for durability, tolerating heat, and has the long span of life. However, it has its own drawback. The joints of the pipe may contain some solders with a lead base. Another concern is that copper is pretty costly since it is a commodity in the marketplace.

PEX pipe

But most homeowners choose the red pipe for lines of hot water supply and blue pipe for the lines of cold water supply. It also features a bit natural curve since it is packed inside the coil. The PEX pipe also shows the markings like the PVC pipe. You do not need to worry about corrosion and rust. But this pipe is never being used for the drain line.
