Product Description
Our 4" Square Steel Tubing with an 11-gauge wall thickness is designed for high-capacity structural applications where maximum span strength and rigidity are required. This cold-rolled mechanical tubing provides a massive profile for structural integrity while maintaining the manageable .120" (approx. 1/8") wall thickness that allows for efficient welding and assembly.
This tubing features a smooth, mill-finish surface that is easy to prep, making it the preferred choice for commercial gate posts, heavy-duty trailer mainframes, and industrial mezzanine supports.
✅ Key Features & Benefits
-
Maximum Structural Rigidity: The large 4-inch profile provides exceptional resistance to bending and deflection over long spans.
-
Industrial-Grade Weldability: Clean carbon steel chemistry ensures excellent arc stability and deep penetration for MIG, TIG, or Stick welding processes.
-
Precise Dimensional Accuracy: Features tight-radius corners and flat, uniform sides for easy alignment of heavy mounting plates and structural brackets.
-
Superior Surface Finish: The cold-rolled process provides a smoother surface than hot-rolled tubing, significantly reducing the labor required for painting or powder coating.
-
High Load Capacity: Designed to handle significant vertical and horizontal loads in commercial and agricultural environments.
