This guide explains what every fabricator and contractor must know before ordering IS 2062 steel: grade, MTC, heat-number traceability, drawing fit and site requirement.
IS 2062 is the Bureau of Indian Standards specification for hot rolled medium and high tensile structural steel. It is the most referenced steel standard in Indian fabrication, PEB construction, industrial sheds and infrastructure projects. Yet many buyers accept material without verifying compliance.
Grades Under IS 2062
IS 2062 covers multiple grades. E250 (formerly Fe 410) is the standard grade used in most fabrication and structural applications, with a minimum yield strength of 250 MPa. E300, E350 and E410 offer progressively higher yield strengths for demanding structural applications. Each grade has defined chemical composition limits for carbon, manganese, sulphur and phosphorus.
Mill Test Certificates
Every consignment of IS 2062 material must be accompanied by a Mill Test Certificate from the producing mill. The MTC confirms heat number, chemical composition, mechanical test results and grade compliance. A MTC from a stockist or trader that does not reference a specific mill heat number is not genuine traceability.
Dimension Tolerances
IS 2062 sections are rolled to defined dimension tolerances. Web depth, flange width and thickness all have permitted variation bands. Material that falls outside these tolerances affects fabrication fit-up, weld quality and structural performance.
Common Supply Risks
Sub-grade material sold as IS 2062, re-rolled sections without mill traceability and fake MTCs are real problems in the Indian steel market. Buying from established, accountable suppliers with genuine mill relationships reduces this risk significantly.
