Round DOM Steel Tubing 1-3/4in x .120in x 12ft

Round DOM steel tubing 1-3/4in x .120in x 12ft is the backbone of serious chassis fabrication, roll cage construction, and custom frame builds. Whether you're engineering a competition race car, reinforcing a lifted truck frame, or building a street rod from the ground up, this drawn-over-mandrel (DOM) tubing delivers the structural integrity and dimensional consistency that separates professional work from amateur attempts. ALLSTAR PERFORMANCE's DOM tube is the trusted choice for fabricators who refuse compromise on quality.

DOM steel tubing is cold-drawn over a mandrel, which removes surface impurities and creates superior concentricity compared to ERW (electric resistance welded) alternatives—critical when you need precision joints and minimal runout during welding. The 1-3/4 inch outer diameter with .120 inch wall thickness strikes the ideal balance between structural rigidity and weldability for mid-size chassis components, intermediate roll cage bars, and suspension hard points. At 25.75 lbs for the 12-foot length, this tubing maintains excellent strength-to-weight ratios essential for performance vehicles. The smooth, consistent interior and exterior surfaces accept TIG or MIG welds cleanly, and the material machines without the brittleness of cast components.

Fabricators, race teams, and custom builders rely on this DOM tubing for applications ranging from full chassis construction to engine bay bracing and suspension triangulation. The 12-foot length minimizes waste on most projects and allows you to cut multiple components without tedious joinery. This material is compatible with all standard welding processes and readily accepts cutting, bending, and machining with conventional shop equipment. Stock this specification for consistent, professional results on every build.
