I have this batch of 5 galvanized steel pipes. All of them are 1" in diameter and there are threaded. The tallest is 8-foot long, and three others are 7-foot tall. There's also a short 3-foot long one. These remained from a construction project we had a few years ago, and although they have been sitting around for a few years, they've never been used. As you can see in the picture, some come with their own joints and fittings. I prefer if you can take all of them, but if you need just one or some, let me know. You can come take a look here at Madinah Hardware in Lweza at the junction of Entebbe road and Kigo road.
