Mild Steel Round Tubing 1-3/4in x .065in x 20ft

The Mild Steel Round Tubing 1-3/4in x .065in x 20ft from ALLSTAR PERFORMANCE is the go-to structural material for fabricating custom chassis, roll cages, suspension components, and frame reinforcement on race cars and performance builds. Whether you're constructing a tube frame, building exhaust headers, or reinforcing a vehicle's structural integrity, this versatile round tubing delivers the strength and workability needed for welded automotive applications. Its 20-foot length provides ample material for most single-component projects or multiple smaller fabrications, making it a cost-effective choice for shops and enthusiasts alike.

Constructed from mild steel, this round tubing offers superior weldability compared to higher-carbon alloys—critical for maintaining heat-affected zone integrity and consistent joint strength during MIG or stick welding. The 1-3/4 inch outer diameter and 0.065 inch wall thickness strike an optimal balance between rigidity and weight savings, providing excellent strength-to-weight ratio for chassis work without excessive mass penalty. At 22.5 pounds total, the tubing remains manageable for manual handling while maintaining sufficient material density to support high-stress structural applications. The uniform wall thickness ensures consistent bend radius and predictable failure characteristics when designing tube bends for suspension links or custom mounts.

Fabricators, race shops, and weekend warriors benefit most from this tubing when building roll cages, ladder bars, A-arms, or reinforcing factory frames on street rods and competition vehicles. Its compatibility with standard cutting tools, tube notchers, and portable welding equipment makes it ideal for both shop and portable fabrication work. The mild steel composition allows for cold-working, heat-treating, and re-welding without brittleness concerns—essential when iterating designs or modifying existing assemblies. For serious automotive fabrication projects requiring reliable, weldable structural material, this ALLSTAR PERFORMANCE round tubing delivers proven performance and repeatability across countless build types.
