The steel shall be classified into three grades: E165, E170, and E215.

The processes used in steel production and further hot rolling into steel strips, sections, flats, bars, etc., are left to the manufacturer’s discretion. Steel must be killed or semi-killed, and all finished steel must be well and thoroughly rolled. The chemical composition must be in accordance with applicable standards. The general requirements for structural steel supply must conform to IS 8910.


Tests shall be carried out in accordance with the method specified.

  • Tensile test
  • Bend test


With the exception of round, square, and hexagonal bars and flats, each product must have a tag or be marked with the manufacturer's name or trade mark. The standard mark (ISI Mark) may also be applied to the material.

The Manufacturer must obtain a BIS license from the Bureau of Indian Standards to use a standard mark (ISI Mark).
