Mild Steel Round Tubing 1-1/4in x .083in x 20ft

The Mild Steel Round Tubing 1-1/4in x .083in x 20ft from ALLSTAR PERFORMANCE is the backbone of custom automotive fabrication, whether you're building a roll cage, chassis reinforcement, or performance exhaust manifold support. This hollow round section tubing delivers the structural integrity needed for race applications, street rod builds, and heavy-duty suspension modifications without the weight penalty of solid stock. Twenty feet of uninterrupted material gives fabricators flexibility to cut multiple frame sections, crossmembers, or mounting brackets from a single piece.

At 1.25 inches outer diameter with a 0.083-inch wall thickness, this mild steel tubing strikes the balance between rigidity and weldability that experienced mechanics demand. The 20.6-pound total weight reflects the material density—roughly 1 pound per linear foot—making it easy to handle during layout and tack-welding operations. Mild steel's lower carbon content compared to alloy tubing means superior arc-welding characteristics; you can work with standard MIG or stick processes without preheating or post-weld stress relief in most applications. The consistent wall gauge ensures predictable bending behavior on a tube bender and uniform strength along the entire 20-foot length.

Fabricators, welders, and DIY builders restoring classic cars, building off-road frames, or reinforcing existing chassis will appreciate the value and versatility this tubing offers. The 1-1/4-inch diameter is ideal for secondary bracing, small-diameter roll cage hoops, and engine bay reinforcement where space is tight but strength is critical. Installation is straightforward—measure your section, cut with a bandsaw or plasma cutter, position, tack-weld, and finish with full-strength beads. Order by the 20-foot length to ensure you have stock on hand for multiple fabrication projects or to minimize waste during complex bends and joints.
