Problems solved by technology

Although the steel will not burn, its mechanical strength will gradually decrease as the temperature rises. When the temperature of the steel material rises to a certain value, the steel will lose its supporting capacity. Therefore, the fire resistance of the steel structure building is better than that of the masonry structure. Much different from reinforced concrete structures
