Round DOM Steel Tubing 1-3/4in x .120in x 17ft

Round DOM Steel Tubing 1-3/4in x .120in x 17ft is the backbone of custom chassis fabrication, roll cage construction, and high-performance suspension builds. Whether you're designing a street rod frame, building a competition roll cage, or engineering a custom suspension geometry, this drawn-over-mandrel steel tubing delivers the structural integrity and precise dimensional consistency that separates professional-grade fabrication from amateur work. DOM tubing is the industry standard for applications where weld quality, concentricity, and load distribution directly impact safety and handling performance.

The 1-3/4 inch outer diameter with .120 inch wall thickness provides an optimal strength-to-weight ratio for mid-range chassis and suspension components, offering substantial rigidity without excessive mass penalty. DOM (Drawn Over Mandrel) manufacturing eliminates seams and internal imperfections, ensuring consistent wall thickness and superior weldability compared to ERW tubing. The 17-foot length—204 inches—minimizes scrap waste on typical multi-component builds, allowing fabricators to maximize material yield across suspension arms, frame sections, and bracing elements. ALLSTAR PERFORMANCE's DOM tubing meets stringent industry standards for dimensional accuracy and material quality, critical factors when precision-fitting components into tight chassis packages.

Professional fabricators, race teams, and serious hot rod builders trust this tubing for applications requiring repeatable welds and predictable load paths. The 1-3/4in diameter is ideal for A-arm construction, trailing arm fabrication, and secondary frame bracing on vehicles ranging from classic muscle cars to modern tube-frame race cars. At 36.6 pounds per length, material handling and positioning during layout and tack-welding remains manageable for solo fabricators or small shop teams. Verify fitment against your specific frame design and consult load-analysis calculations before committing to production; DOM tubing's performance is directly proportional to proper design and welding technique.
