Source notes and corrections
gost:angleIu: The printed Iu values are approximately ten times lower than both A*ru^2 and Ix+Iy-Iv from the same rows. The comparison manufacturer's catalog lists 12200 and 14700 cm4 with matching dimensions, area, mass, Ix and Iv. Adopt the explicitly authorized catalog values, not recalculated values from rounded inputs.
Original source value: 1470
Verified value: 14700
Source publicationAnnex A prints Iu=1220 and 1470 cm4 for 250x250x28 and 250x250x35. Original cells retained; effective Iu corrected to 12200 and 14700 cm4 by explicit user instruction, supported by the comparison source in valueCorrections. This is not an official GOST corrigendum.
