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.

How to Calculate Steel’s Fire Resistance?

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.

Fire Safety Ratings and Testing in India

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.

Finishes, Coatings, and Fire Protection Methods for Manufacturing Fire-Resistant Steel

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.

At SBF Rapid, we use various methods to manufacture fire-resistant steel products that help to prevent the spread of fire and minimize damage to steel structures.

  • What is fire-resistant steel?

    A fire-resistant SBF Rapid Steel TMT bar is made up of fire-resistant alloys containing Chromium, Titanium, and Nickel, which neither degrades in terms of the strength of the TMT Bar, resistance to crack, or any damage to the infrastructure during a firestorm.

    Our TMT bars have AOAS covering to shield against fire storms and remain unaffected up to temperatures as high as 650 degree Celsius.

    Our TMT Bars also show resistance to the spread of fire, affecting the strength of the entire structure, and are certified for meeting excellent standards by Shri Ram Institute of Industrial Research, RSRDC- Jaipur, and Bureau Veritas.

  • How is fire-resistant steel made?

    At SBF Rapid, the manufacturing process of TMT bars takes place with maximum attention to the details and guidelines by BIS to deliver high-grade, powerful, anti-corrosive, and fire-resistant TMT bars.

    The process of manufacturing begins after selecting the best quality of Iron Ore, an anti-corrosive and fore resistant alloy that undergoes.

    • A) Quality check-ups using a spectrometer to test the liquid.
    • B) Automatic Rolling Mill for uniform thickness of the TMT bars.
    • C) Further processing through German Thermax technology for cooling TMT bars in process, using jet sprays to ensure tensile strength that can withstand pressure intensities.
    • D) USM Technology for giving a precision shape of a perfect solid rod.
    • E) AOAS technology to make TMT bars fire-resistant up to temperature 650 Celsius.
    • F) Automatic Straight Bundling technology.

    The final outcome of our entire production process is 550D and CRS TMT Bars, fire-resistant, corrosion-resistant TMT bars, ingots, and billets as per the set parameters of BIS.

    Additionally, we also ensure a cut down on carbon emissions to promote green and environment-friendly manufacturing.
