Round DOM Steel Tubing 1-1/2in x .083in x 12ft

The round DOM steel tubing 1-1/2in x .083in x 12ft from ALLSTAR PERFORMANCE is a cornerstone component for fabricating custom chassis, roll cages, suspension arms, and structural reinforcements in automotive builds. Drawn over mandrel (DOM) construction ensures consistent wall thickness and superior internal surface quality, making this tubing ideal for applications where precision welding and tight tolerances are non-negotiable. Whether you're engineering a race car frame, building an off-road recovery setup, or reinforcing a project vehicle's structure, this 12-foot length provides ample material for multiple fabrication projects without excessive waste.

DOM steel tubing delivers superior weldability compared to standard ERW (electric resistance welded) alternatives because the mandrel process eliminates seams and internal imperfections that can compromise joint integrity under stress. The 1-1/2 inch outer diameter with .083 inch wall thickness strikes an optimal balance between strength-to-weight ratio and workability—thick enough to handle bending and welding operations without deforming, yet light enough (15.58 lbs per 12-foot length) for performance applications where unsprung mass matters. This gauge resists corrosion better than thinner-walled tubing and accepts beveling, notching, and complex geometries required for custom suspension geometry or frame design.

Fabricators, welders, and serious enthusiasts building everything from circle-track race cars to long-travel off-road platforms depend on DOM tubing for structural integrity where failure is not an option. The 12-foot length minimizes joints in linear components like A-arms, trailing arms, and X-bracing, reducing stress concentration points and simplifying assembly. Before welding, degreasing and proper joint preparation ensure maximum penetration; standard oxy-acetylene, MIG, and TIG processes all work effectively with this material. Stock this tubing in your shop for any chassis or suspension project requiring professional-grade structural steel.
