Steel DOM Tubing, 3"X4-1/2"

DOM Tubing, 3"X4-1/2"

The DOM Tubing (3" x 4-1/2") is a heavy-duty Drawn Over Mandrel steel tube designed for strength, precision, and structural reliability in fabrication and mechanical applications. DOM tubing is known for its smooth interior finish, tight dimensional tolerances, and superior strength compared to standard welded tubing, making it a preferred material for high-stress components. With a 3" inside diameter and 4-1/2" outside diameter, this thick-wall tubing provides excellent rigidity for demanding structural and equipment uses—because when steel tubing gets this stout, it’s usually being trusted with a serious job.
