Steel and Iron - Fire resistant Steel- Specification
Summry
Fire resistant steel is a specially engineered structural steel designed to retain strength and load-bearing capacity at high temperatures during fire exposure. Unlike conventional steel, it delays deformation and collapse, making it suitable for buildings, bridges, tunnels, and critical infrastructure requiring enhanced fire safety.
Why BIS Certificate is Mandatory for Fire resistant Stee ?
BIS certification is mandatory to ensure fire resistant steel complies with Indian Standards for high-temperature performance, mechanical strength, and chemical composition. Certification guarantees reliable fire resistance, prevents use of substandard steel in structures, and ensures public safety, regulatory compliance, and uniform quality in construction projects.
What is BIS Certified for Fire resistant Stee ?
The BIS certified specification for fire resistant steel defines requirements for chemical composition, yield strength, elongation, and performance at elevated temperatures. It also specifies testing methods, sampling, marking, and inspection criteria to confirm the steel’s ability to maintain structural integrity during fire conditions.
