Introduction
Rectangular and Square Steel Tubes: Selection Guide for Structural Fabrication Projects is designed to assist engineers and fabricators in navigating the technical complexities of choosing Hollow Structural Sections (HSS). These profiles are among the most versatile components in modern construction and mechanical engineering, valued for their high strength-to-weight ratio and aesthetic appeal. Unlike open sections like I-beams or channels, square and rectangular tubes offer excellent resistance to torsion (twisting) and provide uniform strength in multiple directions. This guide examines the critical factors—ranging from material grades to dimensional tolerances—that must be considered when selecting these tubes for structural applications.
