Mild Steel Round Tubing 1-1/4in x .120in x 12ft

The Mild Steel Round Tubing 1-1/4in x .120in x 12ft from ALLSTAR PERFORMANCE is the backbone of custom chassis fabrication, roll cages, and structural reinforcement in vehicle modification work. Whether you're building a race car frame, constructing a custom bumper assembly, or reinforcing a suspension linkage, this tubing delivers reliable structural integrity at an economical price point. Mild steel tubing is the industry standard for welding applications because it accepts heat and filler material predictably, making it ideal for fabricators of all skill levels.

This tubing features a 1-1/4 inch outer diameter with a 0.120 inch wall thickness, providing an excellent strength-to-weight ratio for high-stress fabrication projects. The 12-foot length allows you to maximize material yield and minimize waste on multi-component builds. Mild steel's machinability and weldability make it superior to alternative materials for frame work, as it doesn't require specialized welding equipment or pre-heating procedures typical of higher-carbon alloys. The consistent wall thickness ensures uniform load distribution across joints and bends, critical for chassis rigidity and longevity under track or off-road conditions.

This tubing suits fabricators building custom frames, welding cages, suspension components, and structural bracing for street rods, drag cars, and off-road vehicles. Its dimensions make it compatible with standard tube notchers and bending equipment found in most fabrication shops. Before welding, degreasing and wire-brushing the surface removes mill scale and ensures strong, clean welds. For applications requiring corrosion resistance, prime and paint immediately after fabrication to extend service life in exposed environments.
