About Rectangular Hollow Sections (RHS)

Rectangular Hollow Sections (RHS) are rectangular tubes used where the loading is different in each axis, such as beams, mullions, and frames. The deeper dimension resists bending while the wider dimension provides lateral stability. Available from 50x25 to 500x300.

This page shows section properties for all 239 standard UK rectangular hollow sections (rhs) 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.
