IS Codes for Structural Steel

Structural steel is an essential material used in the construction industry for creating load-bearing structures such as bridges, buildings, and towers. The Bureau of Indian Standards (BIS) has established a set of standards for structural steel, known as Indian Standard (IS) codes, to ensure the quality, safety, and reliability of steel products used in construction.

IS codes cover a wide range of topics related to structural steel, including the quality of raw materials, mechanical properties, chemical composition, dimensions, and testing procedures. These standards ensure that structural steel products meet specific requirements and are suitable for their intended use. Compliance with IS codes is mandatory for manufacturers, importers, and users of structural steel products.
