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

Square mild steel tubing 1/2 inch x .065 inch x 12 feet is a lightweight structural material engineered for fabrication, repair, and custom builds in tactical, automotive, and industrial applications. This tubing is ideal for gunsmiths, armorers, and equipment manufacturers who demand precision materials for reinforcing firearm components, constructing equipment racks, or fabricating mounting solutions for gear systems.

The mild steel construction delivers excellent machinability and weldability, critical for fabricators who need to drill, cut, and join components with precision. With a wall thickness of .065 inch, it strikes a balance between structural rigidity and material economy, ensuring strength under load while minimizing weight—essential for tactical equipment that must perform reliably without adding unnecessary bulk.

The square profile offers four flat surfaces for secure clamping, mounting, and alignment during fabrication and assembly operations. At a manageable weight, this 12-foot length remains portable for shop work while retaining the durability required for load-bearing applications in harsh conditions. Armorers, gunsmiths, and tactical equipment manufacturers will find this tubing invaluable for custom mounting systems, optic adapters, and reinforcement brackets.
