Premium Steel Tubes & Pipes

Steel and Pipe Supply has a big collection of carbon steel pipes and tubes. You can find them in all sorts of sizes, thicknesses, and lengths. They come in square, rectangle, and round shapes. These are good for projects that need to hold up a lot of weight, or for machines and other equipment. They can even be used instead of angles.

For building stuff, the focus is on how strong the material is. For machines and equipment, the size and type of metal have to be really exact.

They also have big square and rectangle tubes known as HSS. These are a good choice if you need something to hold up a lot of weight but don’t want to spend a lot of money. HSS jumbo tubes are flexible, letting you build all kinds of structures.
