scope:

This European Standard specifies dimensional and cross-sectional tolerances for cold rolled steel sections produced on roll-forming machines. It applies to cold-rolled sections for general use (standard sections) produced from steels conforming to EN 10025, EN 10142 and EN 10147 and in the form of rectangular L, U, C, Z and Omega cross sections as well as split tubes (see Figures 1 to 6). It applies to cold rolled sections for special applications (special sections) produced from steels listed in clause 5 with other radii, tolerances and shapes.
