Mild Steel Round Tubing 1-1/2in x .120in x 20ft

Mild steel round tubing 1-1/2in x .120in x 20ft from ALLSTAR PERFORMANCE is the foundation material for custom chassis fabrication, roll cage construction, and structural reinforcement in high-performance automotive builds. Whether you're designing a street rod frame, competition suspension links, or exhaust manifold collector boxes, this 20-foot length provides ample stock for welding projects without excessive waste. Mechanics and fabricators rely on this tubing for its predictable weldability, straightness, and consistent wall thickness that simplifies fit-and-finish work.

The 1-1/2 inch outer diameter with 0.120 inch wall thickness creates an optimal strength-to-weight ratio for most welded structures, offering superior rigidity compared to thinner-wall alternatives while remaining workable on a standard shop miter saw or tube notcher. Mild steel composition ensures easy tig, mig, or stick welding without preheating or stress-relief cycles, making it ideal for both one-off fabrication and production runs. At 34.125 pounds for the complete 20-foot section, the tubing remains manageable for solo handling during layout and tacking, yet the 0.120 wall provides genuine structural integrity in load-bearing applications.

Fabricators working on tube-frame vehicles, custom suspension A-arms, and engine bay bracing will find this tubing compatible with standard cutting, bending, and welding equipment found in most professional or serious hobbyist shops. The 20-foot length is substantial enough to yield multiple components for a single project—frame rails, cross-members, and secondary bracing—without requiring expensive bulk purchases. Proper surface prep with wire wheel or sandblasting before welding ensures maximum penetration and weld quality; consider painting or coating after fabrication to prevent surface rust during storage and use.
