The fire protection design of steel structure is very important

In modern architecture, steel structure is widely used in various types of buildings because of its superior strength, flexibility and construction efficiency. However, the performance of steel in high temperature environment will be significantly reduced, so the fire protection design of steel structure is particularly important.

Although steel itself does not burn, when exposed to high temperatures in a fire, its strength and stiffness rapidly decrease, potentially leading to structural instability or collapse. Therefore, scientific and reasonable fire protection design is crucial to ensure the safety and stability of steel structure buildings.

Fireproof coating is a common method in fireproof design of steel structure. By coating a layer of fireproof paint on the surface of the steel structure, it can form a thermal insulation barrier in the event of a fire, effectively delaying the rise of the temperature of the steel and maintaining the integrity of the structure. These fire retardant coatings are usually divided into thin and thick two types, the choice should be based on the specific building fire requirements and use of the environment for comprehensive consideration.
