Steel DOM Tubing, 4"X5"

DOM Tubing, 4"X5"

The DOM Tubing (4" x 5") is a precision steel tube manufactured using the Drawn Over Mandrel (DOM) process, producing a smooth interior surface, consistent wall thickness, and superior strength compared to standard welded tubing. DOM tubing is widely used in structural, mechanical, and fabrication applications where strength, dimensional accuracy, and clean finishes are important. The controlled manufacturing process improves concentricity and eliminates the weld seam irregularities found in basic tubing. In other words, it’s the kind of tubing fabricators reach for when the job calls for strength and precision—not just “close enough.”
