Galvanized Pipe for Durability

Galvanized pipe is a steel pipe that's been hot-dipped in zinc for a coating to provide strong resistance to corrosion. It's commonly used for transporting compressed air, potable water, gasoline, oil, gases and more. Lowe's carries a wide supply of galvanized steel pipes in a range of sizes to fit your project. 


Along with straight and strong steel pipes, you'll find galvanized pipe fittings, including couplings, caps, bushings, elbows and more. Use a tee fitting to join two flows into one, or to divide one flow into two. Install a flange fitting to provide extra strength and stability.


Along with fittings, you'll find pipe in an array of sizes. Whether you looking for popular sizes like 2-inch galvanized pipe or less common sizes, it's likely you'll find the right fit at Lowe's. But before you shop, be sure to check out our Pipe Fitting Buying Guide with tips on pipe materials and various fittings.
