Classification Definition

"Rectangular Mechanical Tubing is a welded steel tube used where greater strength is required in one direction. It provides a flat surface for mounting and is efficient for joining and fabrication."

Rectangular Tubing from Vanex Tube is engineered for versatility. Whether for load-bearing frames or architectural elements, our tubing meets strict dimensional specifications. For box-section profiles requiring equal-sided geometry, see our square mechanical tubing. Non-standard cross-sections — flat ovals, D-shapes, and more — are available through our specialty shapes program.

Value-Added Capabilities

  • 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.
