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

The Square Mild Steel Tubing 3/4in x .065in x 20ft by ALLSTAR PERFORMANCE is a versatile structural component engineered for fabrication, repair, and custom assembly work in tactical, automotive, and industrial applications. From reinforcing equipment mounts and building protective frames to constructing specialized gear racks and ballistic barriers, this tubing serves operators, armorers, and fabricators who demand predictable material performance under demanding field conditions. The 20-foot length provides substantial working stock for projects requiring multiple cuts or extended runs without excessive waste.

Constructed from mild steel with a 0.75-inch outer dimension and 0.065-inch wall thickness, this tubing delivers a favorable strength-to-weight balance critical for mobile platforms and load-bearing applications. The square profile provides superior welding surfaces and structural rigidity compared to round tubing, making it ideal for mounting hardware, indexing components, and absorbing lateral stress. Mild steel's inherent forgeability and machinability allow field modification without special equipment, while the material's thermal properties enable heat-treating if hardening is required for high-wear surfaces.

Law enforcement gunsmiths, military armorers, and equipment fabricators benefit from this tubing's dimensional consistency and weldability across extended runs. The 12.5-pound weight per 20-foot section maintains portability while resisting deformation under operational loads. Applications include reinforcing carrier frames, constructing modular mounting systems, fabricating breaching tool housings, and building diagnostic fixtures. Mild steel's bare finish accepts standard coating methods—paint, bluing, or parkerizing—for corrosion protection in field environments.
