Properties - HA: HSS - ASTM A500 Round

Welcome to our HSS Round (ASTM A500) property page. Here you'll find section properties — area, moment of inertia, torsional constant, section modulus and radius of gyration — for every round HSS section in this grade, sourced from CISC 12. Sort by any column to compare sections. ---
