Mild Steel Round Tubing 1-1/4in x .120in x 12ft

Mild steel round tubing 1-1/4in x .120in x 12ft from ALLSTAR PERFORMANCE is engineered for fabricators, welders, and motorsports builders who demand reliable structural components. This 12-foot length tube serves as an ideal base material for chassis construction, roll cages, suspension linkages, and custom frame work across automotive restoration, racing, and industrial applications. The natural mill finish provides a clean substrate ready for welding, painting, or powder coating without surface preparation delays.

The tubing features a 1.25-inch outer diameter with a 0.120-inch wall thickness—a geometry that balances structural rigidity with manageable weight, critical for performance builds where every pound matters. Mild steel construction delivers excellent weldability and formability, allowing builders to bend, cut, and join sections without brittleness or material failure. At 16.67 pounds, this length is substantial enough for main frame rails or roll cage hoops while remaining practical for single-person handling and transport. The consistent wall thickness ensures uniform strength distribution and predictable load-bearing characteristics across the entire 144-inch length.

Professionals in race car fabrication, off-road vehicle modification, and general metalworking rely on this tubing stock for projects requiring precision-cut segments. Its natural finish accepts TIG, MIG, and stick welding processes without coating removal, saving setup time on the job. The 12-foot length minimizes waste on mid-sized projects while offering flexibility for cutting custom diameters and angles. Whether you're building a tube frame chassis, reinforcing structural components, or creating custom suspension geometry, this ALLSTAR PERFORMANCE round tubing delivers the durability and workability expected in demanding fabrication environments.
