Rectangle Steel Tubing 2in x 3in x .083in x 4ft

Rectangle steel tubing 2in x 3in x .083in x 4ft is the backbone of professional-grade fabrication in automotive frame repair, custom chassis builds, and roll cage construction. Whether you're reinforcing a performance vehicle's undercarriage, building a competition suspension frame, or creating a protective roll bar assembly, this ALLSTAR PERFORMANCE tubing delivers the structural integrity that serious builders demand. At 10.14 lbs per 4-foot length, it provides an excellent strength-to-weight ratio for applications where precision engineering meets durability.

The .083-inch wall thickness strikes an optimal balance between rigidity and workability—thick enough to resist bending and torsional stress in high-load scenarios, yet thin enough to allow welding without excessive heat distortion or material brittleness. Cold-formed rectangle tubing resists warping during TIG or MIG welding when proper technique is employed, making it ideal for fabricators who need repeatable, dimensionally accurate joints. The 2-inch by 3-inch cross-section provides two distinct load paths, offering superior performance in both lateral and vertical load applications compared to round tubing of equivalent wall thickness.

Fabricators, restoration specialists, and performance shops rely on ALLSTAR PERFORMANCE tubing for frame-up builds, subframe reinforcement kits, and safety cage assemblies in road-course and drag racing applications. The 4-foot length is versatile enough for single-piece members or quick prototype layouts before cutting longer stock—a smart choice for shops managing material waste on tight budgets. Pair this tubing with quality fasteners, experienced welding practices, and proper heat-treat protocols to achieve automotive-grade structural welds that pass safety inspections and withstand years of dynamic stress.
