DX53D Grade 0.14mm-0.6mm Galvanized Round Steel Pipe G550 St52 S355
How long will galvanized steel last?
The zinc coating of hot-dipped galvanized steel will last in the harshest soil is 35 to 50 years and in less corrosive soil 75 years or more. Although humidity affects corrosion, temperature itself has less of an impact. Galvanized zinc coatings respond well in extreme cold and hot temperatures.
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.
