Mild Steel Round Tubing 1-3/4in x .065in x 12ft

Mild Steel Round Tubing 1-3/4in x .065in x 12ft from ALLSTAR PERFORMANCE is the backbone of custom chassis fabrication, roll cage construction, and structural reinforcement in performance vehicles. Whether you're building a tube frame, designing a custom suspension geometry, or reinforcing stock mounting points, this 12-foot length gives you the flexibility to tackle everything from small brackets to mid-sized subframe components in a single purchase. Mechanics and fabricators rely on this profile for its balance of strength, workability, and cost-efficiency across street cars, track builds, and off-road platforms.

The 1-3/4 inch outer diameter with .065 inch wall thickness delivers excellent structural rigidity while remaining lightweight enough for handling and accurate TIG or MIG welding. Mild steel composition allows straightforward hot and cold forming, making it ideal for bending around suspension mounting points or creating custom control arm geometry without the brittleness of higher-carbon materials. The round profile distributes loads evenly across multiple planes, critical for both torsional rigidity in chassis work and lateral strength in cage designs. At 13.28 pounds for the full 12-foot section, weight stays manageable for a single fabricator while still providing substantial material for multi-part projects or prototype iterations.

Builders working on tube frame replacements, subframe connectors, or roll bar fabrication benefit most from this length and diameter—it covers full door-to-door or front-to-rear runs with minimal joinery. The SKU ALL22144-12 is also available in bulk for shops completing multiple vehicles or constructing full chassis kits. Weldability with standard electrode types ensures compatibility with both professional fabrication shops and experienced home builders equipped with basic welding equipment. Cut-to-length requests from your supplier let you optimize this stock for specific projects, minimizing waste on precision builds.
