Galvanised steel is steel that has had a layer of zinc applied to its exterior in order to prevent it from rusting. The zinc also adds a protective veneer that will protect the steel below from being scratched. Galvanised steel is not suitable if it is exposed to harsh elements such as acid or other highly corrosive materials, however, it is suitable for products that will be exposed to the outdoors. Most commonly, steel is dipped into a vat of molten zinc, coating it in the protective layer evenly.

Galvanised pipe is steel piping coated with zinc to deter rusting. If your house was built before the 1906s, chances are your plumping is constructed from galvanised pipe.

If you have a house that was built before the 1960s, chances are your plumping system is made from galvanised pipe. The anti-rust zinc coating makes it prime for use in plumbing where the metal is constantly exposed to water.


Galvanised pipe has a lifespan of over 40 years. However, elements such as environmental exposure and minerals in your water supply can drastically reduce this. Before choosing galvanised piping, speaking with a plumber is a good idea in order to determine whether it is the right choice for you.

Risks Associated with Galvanised Pipe

Over time, zinc can eventually erode from galvanised pipes. This can lead to an accumulation of lead on the inside of pipes which may contaminate the water supply. The only way to ensure that lead is not mobilised from plumbing to tap in older homes is to fully replace the galvanised plumbing and lead service lines.
