Mild Steel Round Tubing 1-1/4in x .083in x 12ft

The Mild Steel Round Tubing 1-1/4in x .083in x 12ft by ALLSTAR PERFORMANCE is a foundational fabrication component engineered for custom frame building, roll cages, and structural reinforcement in automotive projects. Whether you're constructing a tube chassis, welding a safety cage, or reinforcing suspension geometry, this tubing delivers the material integrity necessary for load-bearing applications where precision and reliability matter. At 11.95 lbs per 12-foot length, it offers an excellent strength-to-weight ratio for builders seeking cost-effective steel without sacrificing structural performance.

Constructed from mild steel with a 1-1/4 inch outer diameter and .083 inch wall thickness, this tubing strikes a practical balance between torsional rigidity and weldability. The nominal dimensions allow seamless integration into MIG and TIG welding setups while maintaining ductility—critical for joints that experience cyclic loading and vibration. The 12-foot straight length minimizes splicing requirements on mid-sized projects, reducing weak points and labor time. Mild steel's forgiving nature makes it ideal for fabricators transitioning from bolt-together kits to full welded frames, as it resists crack propagation better than high-carbon alternatives and responds predictably to heat input.

This tubing suits frame-up restorations, off-road vehicle builds, drag racing chassis, and prototype development where dimensional consistency across a 12-foot section eliminates sorting hassle. Fabricators appreciate the diameter-to-wall-thickness ratio for applications requiring both lateral stiffness and longitudinal flex—essential in suspension arms, A-arm fabrication, and roll cage diagonal bracing. Installation involves standard cutting, jigging, and welding procedures; no special preparation beyond degreasing is necessary before tacking. The tubing integrates seamlessly with gusset plates, nodes, and reinforcement rings common to advanced chassis designs.
