Alum Square Tubing 3/4in x 3/4in x 12ft

The Alum Square Tubing 3/4in x 3/4in x 12ft from ALLSTAR PERFORMANCE is a versatile structural component designed for custom frame fabrication, roll cage construction, and chassis modifications on street rods, race cars, and specialty vehicles. Whether you're building a tube chassis from scratch or reinforcing an existing frame, this lightweight aluminum tubing provides the foundation for precision welding and custom metalwork. It's an essential material for fabricators, hot rodders, and motorsports enthusiasts who demand repeatable accuracy and clean welds in their projects.

Manufactured from high-quality aluminum alloy, the 3/4-inch square profile offers an ideal balance of strength-to-weight ratio for automotive applications where reducing unsprung mass improves handling and acceleration. The 12-foot length allows for efficient layout and minimal waste when cutting sections for frame rails, subframe mounts, or cross-bracing components. At just 4.5 pounds per stick, this tubing is lightweight enough for weight-critical builds—such as vintage restorations or track-focused platforms—while maintaining sufficient wall thickness and structural integrity for welded joints and stress points. The square cross-section simplifies gusset welding, corner bracing, and attachment points compared to round tubing.

This tubing works best for builders tackling independent suspension frames, ladder-bar brackets, engine bay bracing, and roll cage reinforcement on vehicles ranging from vintage hot rods to modern race cars. Professional fabricators and serious DIY mechanics will appreciate the consistency and weldability that ALLSTAR PERFORMANCE delivers—ensuring clean, repeatable joints without porosity or cracking. The 12-foot length is ideal for projects requiring multiple frame sections, and the tubing's dimensional accuracy makes layout work faster and fitment tighter. Use a quality MIG or TIG welder with aluminum-compatible settings, and always deburr tube ends before welding to achieve professional-grade results.
