Product Description
Our 1-1/2" Square Steel Tubing with an 11-gauge (approx. 1/8") wall thickness is the industry standard for high-strength frames and supports. Manufactured to ASTM A513 standards, this cold-rolled mechanical tubing provides a smooth, mill-finish surface that is exceptionally easy to prep for welding, painting, or powder coating.
The 1.5-inch profile combined with the 11-gauge wall offers significant rigidity and load-bearing capacity, making it the professional choice for utility trailer frames, heavy-duty racking, and agricultural equipment repairs where weight and strength must be carefully balanced.
✅ Key Features & Benefits
-
Professional 11 GA Wall: Provides robust structural integrity and high resistance to bending and torsion compared to lighter 14-gauge tubing.
-
Exceptional Weldability: Clean carbon steel composition ensures strong, consistent welds using MIG, TIG, or Stick processes.
-
Precision Corners: Tight radius corners and flat sides allow for perfect alignment in multi-joint assemblies and miter cuts.
-
Paint-Ready Surface: The cold-rolled finish is smoother than hot-rolled tubing, significantly reducing the amount of sanding and prep needed for a high-quality finish.
-
Versatile Size: The 1-1/2" dimension fits most standard industrial mounting brackets and hardware.
