Square Mild Steel Tubing 1/2in x .065in x 12ft

Square mild steel tubing 1/2in x .065in x 12ft is a versatile structural and fabrication component trusted by armorer shops, tactical equipment manufacturers, and field repair teams across law enforcement and military operations. This product serves as the backbone for custom equipment builds—from mounting solutions and equipment racks to structural reinforcement in mobile command posts and vehicle-mounted systems. The 12-foot length provides enough material for multiple projects without excessive waste, making it economical for both prototype development and production runs.

The 1/2-inch square cross-section with .065-inch wall thickness delivers a balance of structural rigidity and workability that experienced fabricators demand. Mild steel construction accepts welding, drilling, and threading without brittleness, and the uniform wall thickness ensures consistent load distribution across custom-built frames and supports. At 4.5 pounds per 12-foot section, the tubing remains manageable for single-technician handling while maintaining sufficient material density for load-bearing applications. This gauge and profile are ideal for precision drilling and tapping—critical for mounting optics, rails, or modular accessories on field-expedient platforms.

Armory specialists and tactical equipment OEMs benefit most from this tubing when fabricating custom weapon mounts, scope rings, or support structures that demand exacting tolerances and repeatable geometry. Installation is straightforward—cut to length using standard band saws or angle grinders, then weld, bolt, or thread as your application requires. The ALLSTAR PERFORMANCE designation ensures consistent material properties batch-to-batch, essential when manufacturing multiple units that must maintain identical fit and function. Pre-galvanizing is not standard; plan for surface treatment or protective finish if outdoor exposure is anticipated.
