There has been an increasing demand for fire resistant steel in India over recent years due to the growing concern for public safety and the prevention of fire-related incidents. Steel is a popular construction material, but it is not immune to fire damage. Therefore, fire-resistant steel has become a crucial component in buildings, bridges, and other structures.
The fire resistance of steel is calculated based on the fire resistance rating (FRR), which is determined using the Fire Resistance Test (FRT) as per the Indian Standard (IS) code. The FRR is a measure of the time that a material can withstand a fire without losing its structural integrity or functionality.
The FRT involves exposing the steel to high temperatures for a specified period while measuring its temperature rise, deflection, and load-carrying capacity. The FRR is then determined based on the results of the test, with the highest rating being F240, which indicates that the steel can withstand a fire for 240 minutes or four hours without collapsing.
The Bureau of Indian Standards (BIS) has set guidelines and standards for fire safety ratings and testing in India. The BIS guidelines specify the minimum fire resistance rating required for different types of buildings and structures. For instance, residential buildings must have a fire-resistance rating of at least 1 hour, while commercial buildings must have a fire-resistance rating of at least 2 hours. Therefore, manufacturers of steel products such as TMT bars manufacturers must ensure their steel structures go through fire resistance testing in accordance with the BIS standards to ensure compliance.
In addition to the FRR, other important fire safety ratings for steel include the flame spread index (FSI), which measures how quickly fire spreads across the surface of the material, and the smoke-developed index (SDI), which measures the amount of smoke produced by the material when exposed to fire.

There are various finishes, coatings, and fire protection methods that can enhance the fire resistance of steel structures. One of the most common methods is the application of intumescent coatings, which expand when exposed to fire, forming a protective barrier around the steel. This can significantly improve the fire resistance of steel structures. Other methods include the use of fireproofing sprays, fire-resistant insulation, and fire-resistant sealants.
