WebStructural steel fire protection can help ensure this. Exposure to fire can seriously damage the frame and lead to building collapse. While it may not melt until reaching more than 1,300°C1, structural steel will begin to weaken at about 300ºC and increases rapidly after 400ºC. At 550ºC steel loses approx. 40% of its load bearing strength.
