​Steel structures have an Achilles heel: poor fire resistance. In order to keep the strength and stiffness of the steel structure for a long time in the fire, and protect the safety of people's life and property, a variety of fire protection measures are adopted in the actual project.

Why Do Steel Structures That Do Not Burn Need Fire Protection?


Steel is a building material that does not burn. Compared with concrete, steel has many ​exposed  steel beams fire protection such as earthquake resistance and bending resistance. Therefore, in modern buildings, steel structures are widely used, not only to relatively increase the load capacity of buildings, but also to meet the needs of architectural design aesthetic modeling, such as various single-story or multi-story factories, skyscrapers, warehouses , waiting rooms The hall is generally designed with steel structure.

Although steel will not burn, it will deform when exposed to high temperatures, resulting in structural collapse. As a building material, steel has some unavoidable defects in fire prevention. Generally, the fire resistance limit of unprotected steel structures is about 15 minutes. Usually, at a temperature of 450~650C, the bearing capacity will be lost, and great deformation will occur, resulting in the bending of steel columns, steel beams and even structural collapse.

Fire Protection Measures For Steel Structures


According to different fire prevention principles, the fire protection measures for steel structures are divided into heat resistance methods and water cooling methods.


The heat resistance method can be divided into the spray method and encapsulation method.
