About Square Hollow Sections (SHS)

Square Hollow Sections (SHS) are square tubes used as columns, posts, frames, and general structural members. They offer good compression resistance and a clean appearance. Like CHS, they have equal properties in both axes. Available from 20x20 to 400x400.

This page shows section properties for all 147 standard UK square hollow sections (shs) from the Tata Steel Blue Book (SCI P363). Properties include dimensions, cross-sectional area, second moment of area, elastic and plastic section modulus, radius of gyration, and torsional properties. All values are per BS 4-1:2005 / BS EN 10365.
