What are the disadvantages of galvanized steel?
As with any kind of steel finishing, galvanized steel has its cons, which include:
There can be a high cost associated with galvanization, especially in large-scale projects. ...
Although resistant to red rust, galvanized steel can develop white rust over time if exposed to moisture.
Is galvanized pipe OK for water?
Possible but not recommended. Galvanized pipes can be used as drinking water pipes, but the water must be boiled for drinking. However, after a long time of use, the lead and zinc in the galvanized pipe will precipitate into the water, and the pipe wall is prone to scale.
