Classification Definition

"Square Mechanical Tubing is a box-section steel tube valued for its strength and ease of fabrication. It is commonly used in construction and equipment manufacturing where multi-axis loading is present."

Our Square Mechanical Tubing offers excellent weldability and formability. The uniform grain structure ensures reliable performance in structural applications. Vanex also manufactures rectangular tubing for applications requiring greater strength in one direction, and round tubing where cylindrical profiles are required. For non-standard cross-sections, see our specialty and custom shapes.

Fabrication Capabilities

  • Squaring: Tight tolerance control
  • Corner Radii: Controlled for aesthetic and functional needs
  • I.D. Flash Scarfing: Vanex utilizes I.D. scarfing for removal of the I.D. Flash, which is more precise than I.D. Rolling. This also enables us to provide an I.D. Undercut condition, if so desired.
