Tata Steel has developed a hot-rolled, fire-resistant E350 structural steel designed to improve the safety and resilience of buildings and engineering structures during fires. The new steel has received certification from the Bureau of Indian Standards (BIS) under IS 15103, the Indian standard for fire-resistant structural steel. The key feature of the newly developed E350 structural steel is its ability to retain approximately two-thirds of its yield strength at a temperature of 600°C for up to three hours. This performance can help structural components maintain their load-bearing capacity for longer during a fire, potentially giving building occupants more time to evacuate safely. Tata Steel's fire-resistant steel is intended for manufacturing structural components used in construction and engineering projects. Its potential applications include: Structural hollow tubes: For use in structural systems requiring improved fire performance. Pre-engineered buildings: For industrial facilities, warehouses and other large-span structures. Engineering infrastructure: For applications where maintaining structural integrity during a fire is important. The product adds to Tata Steel's portfolio of specialised, value-added steel products developed to address evolving requirements in construction, infrastructure and industrial engineering. The certification under IS 15103 confirms that the new steel meets the applicable Indian standard for fire-resistant structural steel. The development comes as fire safety and structural resilience become increasingly important in modern buildings, industrial facilities and infrastructure projects. Tata Steel operates across several international markets, including India, the Netherlands, the United Kingdom and Thailand. According to GMK Center, the company's consolidated annual steelmaking capacity stood at approximately 35.9 million tonnes, with plans to increase it to 51.5 million tonnes by the 2030–31 financial year.Tata Steel's New Steel Can Retain Strength at 600°C
According to Tata Steel, the material's improved heat resistance comes from an advanced alloy design that combines optimised microalloying elements with microstructural engineering. This approach helps the steel retain its strength under high-temperature conditions.Applications in Pre-Engineered Buildings
