Square Mild Steel Tubing 1-1/2in x .083in x 12ft

Square mild steel tubing 1-1/2in x .083in x 12ft from ALLSTAR PERFORMANCE is the foundation material for custom frame fabrication, roll cage construction, and structural reinforcement in automotive builds. Whether you're designing a competition suspension geometry, building a custom chassis from scratch, or reinforcing critical load paths in a modified vehicle, this tubing offers the versatility and strength needed for precision welding and structural integrity. The 12-foot length provides ample material for complex multi-piece assemblies without excessive waste or multiple order complications.

The 1-1/2 inch outer diameter with .083 inch wall thickness delivers an optimal strength-to-weight ratio essential for performance applications where every pound matters. Mild steel composition ensures superior weldability compared to high-carbon or alloy variants—critical when executing complex joint geometry or continuous welds under variable thermal conditions. This wall gauge resists deformation under load while remaining workable for bending, drilling, and custom fitment without specialized equipment. At 17.7 pounds total weight, the material density allows builders to construct rigid structural components without excessive added mass to the unsprung or sprung portion of the chassis.

Fabricators, frame shops, and serious weekend builders benefit most from this tubing when constructing custom A-arms, subframe connectors, engine bay bracing, or competition-grade roll cages. The straight 12-foot format is ideal for cutting nested components with minimal material loss, making it cost-effective for prototype development or small-batch custom work. Compatibility spans all welding processes—MIG, TIG, stick—and the mild steel accepts paint, powder coat, and protective finish without surface preparation complications. Installation involves standard cutting, bending, and welding techniques familiar to any experienced automotive technician or fabrication shop.
