Light steel frame (LSF) buildings are celebrated for their sustainability, durability, and efficiency in construction. However, fire safety remains a significant concern due to the thermal properties of steel, which loses strength at high temperatures. This paper examines the principles and strategies that enhance fire resistance in LSF buildings, focusing on the use of fire-rated materials, advanced insulation techniques, and innovative protective technologies. Real-world case studies and advancements in fire protection systems are also discussed to highlight best practices in ensuring the safety and resilience of LSF structures.
