Square Mild Steel Tubing 2in x .083in x 12ft

Square mild steel tubing 2in x .083in x 12ft from ALLSTAR PERFORMANCE is a fundamental building material for custom automotive fabrication, chassis work, and frame reinforcement. Whether you're constructing roll cages, building custom tube chassis, reinforcing pickup bed frames, or creating suspension brackets, this versatile tubing serves as the backbone for serious vehicle modifications. Mechanics and fabricators rely on mild steel square tube for its weldability, structural integrity, and cost-effectiveness compared to chromoly alternatives when raw strength and durability are the primary concerns.

The 2-inch outer dimension with .083-inch wall thickness provides an ideal balance between weight savings and load-bearing capacity for mid-range automotive applications. Mild steel's low carbon content makes it exceptionally weldable—you can join sections without complex heat-treating procedures or specialized welding equipment, a critical advantage in field fabrication and repair work. At 23.36 pounds per 12-foot length, this tubing remains manageable for single-person handling while delivering sufficient wall thickness to resist bending and twisting forces encountered in frame modifications, cross-members, and structural reinforcements. The square profile distributes loads evenly and allows clean, flush gusset welding without complex compound angles.

Fabricators building street rods, off-road buggies, race chassis, and truck bed supports benefit most from this proven tubing stock. The 12-foot length minimizes waste on typical automotive projects—roll cage designs, frame extensions, and modular sub-frame assemblies can be cut and configured with minimal leftover material. Before welding, ensure your work area is properly ventilated and that you're using appropriate filler material and welding parameters for mild steel; most standard MIG and stick welding setups handle this tubing without modification. Finishing with primer and paint after fabrication prevents surface oxidation and extends the life of your custom metalwork.
