How long does it take for galvanized pipe to rust?
Why Are Water Pipes Galvanized Water pipes are galvanized to prevent rusting. The benefit of zinc is that it is slow to oxidize. Even the thin layer that coats galvanized water pipes is enough to protect the iron or steel from rust for decades. Without the zinc, iron and steel can start to rust within a year or two.
Does galvanized pipe rust on the outside?
