Types of Steel Tubing


Steel tubing is commonly grouped into square, rectangular, and round shapes. Contact United Ornamental Supply to confirm current availability for the dimensions and quantities required:


Square Tubing


Square steel tubing provides excellent structural integrity. It is ideal for framework applications. Common sizes range from 1/2" x 1/2" to 8" x 8", with wall thicknesses from 16 gauge to 1/4". Square tubing is perfect for:


  • Structural frameworks

  • Gate construction

  • Furniture fabrication

  • Architectural elements


Rectangular Tubing


Rectangular tubing offers the strength of square tubing with added versatility. This is useful for applications requiring different dimensional ratios. Popular sizes include 1" x 2", 2" x 3", and 3" x 6". Rectangular tubing excels in:


  • Handrail systems

  • Trailer frames

  • Equipment supports

  • Custom fabrication projects


Round Tubing


Round steel tubing provides uniform strength in all directions. It is essential for applications requiring smooth, curved aesthetics. Available in sizes from 1/2" to 8" diameter, round tubing is ideal for:


  • Ornamental scrollwork

  • Balusters and spindles

  • Pipe applications

  • Decorative elements


Selection Criteria


When selecting steel tubing for a project, consider these key factors:

For current steel tubing availability, contact United Ornamental Supply with the required shape, outside dimensions, wall thickness, length, quantity, and project date. Structural selections and substitutions should follow the approved plans and qualified professional direction.
