Round Steel Tube & Pipe

Steel tubing can come in a variety of shapes and sizes, with one of the most common being round. Often made by forming sheet steel into a cylindrical shape and welding the two edges together where they meet, round tubing has very high flex and torsional strength compared to other tubing shapes. Ideal applications include stadiums, bridges, buildings, and other structures, as well as OEM applications like oilfield construction and heavy equipment.

We stock HSS Round 3” OD through 6” OD with 10” OD. We stock Pipe ½” STD through 20” XH, as well as new Jumbo Round Tubing. Our selection of HSS Round & Pipe is cold-formed, welded carbon steel. Service Steel Warehouse offers a variety of ready-to-ship round tubing and pipe in standard sizes and lengths, as well as offers full-service processing capabilities, such as cutting to the desired length or galvanizing.

Round Tubing FAQs

HSS stands for hollow structural section and refers to metal products with a hollow tubular cross-section. The majority of HSS are either round or rectangular/square, but other shapes (such as elliptical) also exist.

Steel pipe is always round, while steel tubing comes in a variety of shapes. They are also used for different purposes, with pipes typically carrying liquid or gas and tubes providing structural support. For a full explanation of their difference, see our Steel Tube & Pipe Differences resource.
