Square Mild Steel Tubing 3/4in x .065in x 12ft

Square mild steel tubing 3/4in x .065in x 12ft from ALLSTAR PERFORMANCE is an essential structural component for fabricators, frame builders, and custom automotive enthusiasts engaged in welded assemblies. This tubing is ideal for constructing roll cages, chassis braces, roll bars, and custom exhaust manifold supports, providing the rigidity that modern performance builds require.

At 6.8 lbs per 12-foot section, it offers a balance of material economy and strength, making it suitable for projects where weight and cost are critical. The 3/4-inch square profile enhances torsional and bending stiffness compared to round tubing of equivalent weight. With a wall thickness of .065 inches (18 gauge), it is robust enough to withstand welding heat and vibration without warping, while remaining lightweight for various applications.

This tubing excels in applications such as cage construction and subframe reinforcement, making it a preferred choice for street machines and track cars. Its mild steel composition ensures excellent weldability across common processes like MIG, TIG, and stick welding, allowing both professional fabricators and serious home shop builders to work with confidence.
