Square Mild Steel Tubing 1-1/2in x .083in x 4ft

The ALLSTAR PERFORMANCE Square Mild Steel Tubing 1-1/2in x .083in x 4ft (ALL22175-4) is a versatile structural steel component engineered for welding, fabrication, and custom frame assembly in motorsports, automotive restoration, and industrial applications. This 4-foot length of square tubing provides a solid foundation for roll cages, chassis components, exhaust systems, and structural reinforcement where moderate wall thickness and mild steel composition deliver reliable performance at competitive cost.

Specifications break down to a 1.5-inch outer dimension with 0.083-inch wall thickness, balancing strength-to-weight for applications requiring structural integrity without excessive material. The mild steel composition accepts standard MIG and TIG welding techniques without special preparation, making it ideal for fabricators and builders who need predictable weldability. At 5.91 lbs per 4-foot section, this tubing remains manageable for hand-positioning during assembly while maintaining the rigidity necessary for load-bearing applications. The natural finish arrives ready for immediate use or surface preparation for paint, powder coating, or protective treatments in corrosive environments.

This product serves fabricators, motorsports builders, automotive restoration specialists, and DIY engineers constructing custom frames, bumpers, rollover protection systems, or structural supports. The square profile provides consistent geometry for welding joints at 90-degree angles and simplifies fixture setup during fabrication. Whether building a race car frame, reinforcing a classic car chassis, or creating industrial equipment, the ALL22175-4 delivers the dimensional consistency and material quality expected from ALLSTAR PERFORMANCE's reputation in the motorsports supply market.

Square steel tubing remains the go-to choice in fabrication where round tubing offers insufficient load distribution or where orthogonal mounting surfaces are required. The 1.5-inch size sits in the optimal range for mid-scale structural work—large enough to resist bending under typical loads, compact enough to fit tight spaces and weight-sensitive builds. For serious fabricators and enthusiasts purchasing square steel tubing online, having a trusted supplier stocking the exact sizes and quantities you need eliminates delays and ensures project continuity.
