This standard BS EN 10210-2:2019 Hot finished steel structural hollow sections is classified in these ICS categories:
77.140.75 Steel pipes and tubes for specific use
This document specifies tolerances for hot finished circular, square, rectangular and elliptical structural hollow sections, manufactured in wall thicknesses up to 120 mm, in the following size ranges: - Circular: Outside diameters up to 2 500 mm; - Square: Outside dimensions up to 800 mm × 800 mm; - Rectangular: Outside dimensions up to 750 mm × 500 mm; - Elliptical: Outside dimensions up to 500 mm × 250 mm. The formulae for calculating sectional properties of sections manufactured to the dimensional tolerances of this standard, to be used for the purposes of structural design, are given in Annex A. Dimensions and sectional properties for a limited range covering the more common sizes are given in Annex B. NOTE The designation of the sections' major axis (yy) and minor axis (zz) aligns with the axis designation used for structural design in the structural Eurocodes.
