Producers: SAIL · TATA · JSW · RINL

Engineering Note: All properties per IS 808:2021. Fy and Fu are nominal values per IS 2062:2011 — use actual mill certificate values for design. Plastic modulus S_xx used for plastic design per IS 800:2007 Clause 8.2.2. Radius of gyration r_yy governs lateral-torsional buckling (Cl. 8.3). Always verify dimensions against current edition of IS 808 before use in fabrication drawings.
