Square Mild Steel Tubing 3/4in x .065in x 20ft

Square mild steel tubing 3/4in x .065in x 20ft from ALLSTAR PERFORMANCE is a foundational structural component trusted across tactical fabrication, vehicle modification, and equipment manufacturing. Law enforcement armorers and military logistics personnel rely on this material for building reinforced frames, mounting systems, and load-bearing assemblies where predictable strength and weldability are non-negotiable. The 20-foot length delivers material efficiency for multi-component builds without excessive waste, making it the standard choice for field-expedient construction and OEM fabrication shops.

The 3/4-inch outer dimension with .065-inch wall thickness creates a lightweight yet rigid tube that handles moderate torsional and bending loads while remaining manageable for hand-tool assembly in austere conditions. Mild steel composition ensures superior weldability compared to higher-carbon alternatives—critical when field repairs or custom modifications are required without specialized equipment. The square profile provides flat bearing surfaces and simplified fastening geometry, eliminating the machining complexity of round tubing. At 12.5 pounds total weight, this 20-foot section maintains portability while delivering the structural integrity demanded by ballistic barrier frames, equipment racks, and tactical vehicle reinforcement.

Professional fabricators—including armored vehicle outfitters, range infrastructure builders, and law enforcement maintenance technicians—specify this tubing for its proven performance in high-stress applications. Stock-keeping across tactical supply chains benefits from its universal dimensions and compatibility with standard fastening hardware. Suitable for cutting, drilling, bending, and welding using conventional shop tools, the square mild steel tubing integrates seamlessly into both retrofit projects and ground-up builds. Ordering in 20-foot lengths allows job-lot planning and reduces per-unit material cost for large-scale tactical equipment programs.
