Why are water pipes Galvanised?
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.
Is galvanized metal lead free?
Lead is not purposely added to galvanizing baths, rather it is an impurity in zinc. This creates thinner galvanized coatings that have less runs and drips. Bismuth is sometimes added to galvanizing baths to achieve the same effect as lead has when types of zinc are used that have very low levels of lead.
