Steel and Iron - Structural Steel (Ordinary Quality)
Summry
Structural Steel (Ordinary Quality) is a type of carbon steel used for general construction purposes, such as beams, columns, angles, and channels. It provides adequate strength, ductility, and weldability for buildings, bridges, and industrial structures. It is suitable for standard load-bearing applications without special mechanical or chemical requirements.
Why BIS Certificate is Mandatory for Structural Steel (Ordinary Quality) ?
BIS certification is mandatory to ensure that structural steel meets Indian Standards for chemical composition, tensile strength, and dimensional tolerances. Certification prevents the use of substandard or unsafe steel in construction, ensures structural safety, supports quality consistency, and protects lives and property from risks associated with weak or defective steel.
What is BIS Certified for Structural Steel (Ordinary Quality) ?
BIS certified specification for Structural Steel (Ordinary Quality) is defined under IS 2062 / IS 226. It specifies chemical composition, mechanical properties, surface quality, permissible tolerances, and testing methods. Compliance ensures steel is safe, durable, and suitable for general structural applications in buildings, bridges, and industrial infrastructure.
