Mild Steel Round Tubing 1-3/4in x .109in x 7.5ft

Mild steel round tubing 1-3/4 inch diameter with .109 inch wall thickness is the backbone of custom chassis fabrication, roll cages, and structural reinforcement in performance builds. Whether you're constructing a tube frame for a race car, building a roll bar assembly, or reinforcing a vehicle's structure for off-road duty, this 7.5-foot length from ALLSTAR PERFORMANCE provides ample material for single or multiple projects. Fabricators and mechanics choose this tubing for its balance of workability and strength—mild steel accepts welds cleanly, bends without brittleness, and machines predictably, making it ideal for both precision and field repairs.

The 1.75-inch outer diameter delivers exceptional stiffness-to-weight ratio critical in suspension components, subframe triangulation, and support bracing. Wall thickness of .109 inches ensures adequate material for tig or mig welding without excessive heat distortion while maintaining reasonable weight at 21 pounds per section. Mild steel's lower carbon content compared to chromoly means reduced hardness but superior ductility—essential when you're bending, forming, or performing field straightening without cracking. This tubing resists stress concentration at welds and handles vibration cycles typical in race and off-road applications without fatigue failure.

Professional fabricators and weekend builders benefit equally from this tubing's versatility in custom motor mounts, transmission crossmembers, exhaust system hangers, and lateral support bars. The 7.5-foot length accommodates full-length frame rails or multiple component sections without excessive waste. Mild steel finishes well with standard paint or powder coat after basic surface prep, and it responds reliably to cutting, drilling, and fitting operations using standard shop tools. Installation requires only basic tig or mig welding equipment and proper joint preparation—no exotic procedures or exotic rod requirements that chromoly demands.
