Steel structure is a structure composed of steel materials, is one of the main building structure types, the structure is mainly made of steel beams and steel plates, steel columns, steel trusses and other components, and the use of silanization, pure manganese phosphating, washing and drying, galvanized rust prevention process, the components or components are usually welded seams, bolts or rivets connected.

Guangdong Steel Structure Company talked about steel structure in the fire protection can take a variety of measures to improve its fire performance.

Here are some common methods:

Spraying fire retardant paint: This is a simple and effective fire prevention method, you can spray a layer of fire retardant paint on the surface of the steel structure to improve its fire resistance. The fireproof coating can form a protective film, which can delay the heating rate of the steel, so as to play the role of fire prevention.

Coated with fireproof material: Coated with a layer of fireproof material on the surface of the steel structure, such as fireproof board, fireproof rock wool, etc., can effectively isolate the fire source and delay the spread of the fire. This method is usually suitable for some places with high fire protection requirements, such as high-rise buildings and petrochemical facilities.

Fireproof paint method: The use of fireproof paint on the steel structure, can play a role in fire protection. Fire retardant paint is a special paint that can form a layer of insulation at high temperatures, thereby protecting the steel structure from being burned.

Water shower and water-filled cooling method: This method is to set a water cooling system inside the steel structure, and reduce the temperature of the steel through water circulation, so as to play the role of fire prevention. This method is usually suitable for some large steel structure facilities, such as steel plants, oil refineries, etc.

Structural optimization design: Through reasonable structural optimization design, the thermal stress concentration and temperature deformation of the steel structure can be reduced, and the overall stability can be improved. For example, the use of reasonable cross section shape, size and connection mode in the design of steel structure can improve the fire resistance of steel structure.
