Properties

RHS properties explained

These properties are especially relevant when comparing RHS. View the complete property glossary.

Symbol Property Units Why it matters
Weight Weight lb/ft, kg/m Mass per unit length; used for self-weight and economy comparisons
Height Outside height in, mm Outside height of a rectangular or square HSS
Width Outside width in, mm Overall width (angle leg or HSS side)
t Thickness in, mm Leg thickness for angles
A Cross-sectional area in², mm² Total steel cross-sectional area
Ix Moment of inertia (x) in⁴, mm⁴ Major-axis flexural stiffness
Iy Moment of inertia (y) in⁴, mm⁴ Minor-axis flexural stiffness
Sx Elastic section modulus (x) in³, mm³ Elastic bending property about the x-axis
Sy Elastic section modulus (y) in³, mm³ Elastic bending property about the y-axis
Zx Plastic section modulus (x) in³, mm³ Plastic bending property about the x-axis
Zy Plastic section modulus (y) in³, mm³ Plastic bending property about the y-axis
rx Radius of gyration (x) in, mm Strong-axis radius of gyration
ry Radius of gyration (y) in, mm Weak-axis radius of gyration and lateral stability relevance
J Torsional constant in⁴, mm⁴ Torsional constant
