Why Should Steel Structures Take Fire Protection Measures

Why should steel structures take fire protection measures?

For many years, steel structures have been widely used in various fields of construction due to their various performance advantages, especially large-span workshops, venues.

However, as a building material, steel has some unavoidable defects in terms of fire protection. 

Its mechanical washing energy, such as yield point, tensile elastic film amount, etc., will decrease sharply due to the increase of temperature.

For example, when the steel structure is usually at 450-650 degrees Celsius, it will lose its bearing capacity and undergo great deformation, resulting in the bending of steel columns and beams, and loss of life and property.

Generally, the fire resistance rating of unprotected steel structures is about 15 minutes.

Therefore, it is necessary to take fire protection measures for steel structures. 

As the steel structure building bearing capacity, CONING glass wool is the best choice with light weight and fire proof Class A performance.
