Square, rectangular, and round steel tubing can be manufactured by roll forming steel sheets into a cylinder shape and then welding the seam where the two edges meet. This roll forming process can be done through hot rolling or cold rolling, although cold rolling results in tighter tolerances and smoother finishes. The different shapes of steel tubing have a wide array of applications and uses, from car suspension to scaffolding to refrigerator tubing.

Steel Tubing FAQs
Used primarily for structural purposes, steel tubing is commonly used for construction scaffolding, railings, automotive applications, pipelines, and more.
Steel tubes are commonly categorized as welded and seamless, which identifies how they were manufactured. Welded tubes are made by rolling steel strips, sheets, or plates into a tube shape and then welded along where the edges meet. Seamless tubes take a cylindrical billet of steel and use a mandrel rod to extrude the center and create a hollow tube. Service Steel primarily stocks welded steel tubing.
