A500 American Standard Square & Rectangular Hollow Sections (SHS/RHS) are square or rectangular steel tubes manufactured in accordance with ASTM A500GR standards established by the American Society for Testing Materials (ASTM).
These sections are produced using cold-formed or hot-rolled processes, with common size ranges from 1 inch to 16 inches and wall thicknesses from 0.065 inch to 0.625 inch.
A500 SHS/RHS are classified into three grades (A, B, C) based on their strength, chemical composition, and mechanical properties.
