Round DOM Steel Tubing 1-5/8in x .120in x 12ft

Round DOM steel tubing 1-5/8in x .120in x 12ft from ALLSTAR PERFORMANCE is the foundation for professional-grade chassis fabrication, roll cage construction, and custom frame builds in high-performance automotive applications. Whether you're building a competition race car, reinforcing a custom hot rod frame, or constructing protective roll bars for track duty, this seamless DOM (Drawn Over Mandrel) steel tubing delivers the structural integrity and consistent wall thickness that separates engineered builds from weekend warrior projects. DOM tubing is the industry standard for welded automotive structures because it eliminates the guesswork of inconsistent material properties that plague cheaper alternatives.

The 1-5/8 inch outer diameter with 0.120 inch wall thickness strikes the optimal balance between structural rigidity and weight savings—critical when you're designing subframes, A-arm assemblies, or suspension pickup points. DOM steel's drawing process ensures uniform grain structure and superior weldability across the entire 12-foot length, eliminating porosity and inconsistencies that weaken joints under load. The material's high carbon content provides excellent tensile strength while remaining formable, allowing fabricators to bend and shape components without sacrificing integrity. This 24-pound tube maintains tight dimensional tolerances, ensuring predictable fitment and repeatability across multiple chassis components or batch fabrication runs.

Serious fabricators, race teams, and restoration shops rely on ALLSTAR PERFORMANCE DOM tubing for applications demanding SFI compliance, sanctioning body approval, and long-term durability in extreme conditions. The 12-foot length accommodates most single-car projects with minimal waste, whether you're cutting floor pans, ladder bars, or main chassis rails. TIG welding produces the cleanest results, though MIG techniques work reliably with proper technique. Stock this tube for ongoing projects, or order multiples for fleet builds—consistent material sourcing ensures identical properties across every component.
