2022 / 12 / 22

Shandong Wiskind Architectural Steel Co., LTD. Uses the full high density hydrophobic rock wool core material, double-sided coated steel plate, bonded and Chengli Caicaijin ® fire proof board, to meet the strict fire protection requirements, fire resistance limit at 1000℃ for more than 4 hours, and does not emit toxic and harmful gases, fire performance reaches the national A class standards.

Why do steel structures need fire protection

Steel structure buildings take some proportion in the existing buildings in our country, especially the big frame traffic buildings, industrial buildings, high-rise buildings, sports centers, exhibitions and so on. Under high fire temperature, the steel structure without fire protection will collapse in about 15 minutes, causing great harm. Therefore, the fire prevention of steel structure buildings is very important for the life and property safety of such building users.


Methods of fire prevention in steel structures

In order to reach the fire resistance limit of steel structure design, GB51249-2017 "Technical Specification for Fire Protection of Steel Structures in Buildings" provides the fire protection measures that can be adopted for steel structures, including fire-resistant coating, fire-proof board coating, flexible felt-like material coating, outsourced concrete and other ways. Steel structure fire protection needs to maintain good physical and chemical properties for a long time to play a protective role in fire. Cladding fire-proof board has good durability and has been used in prefabricated steel structure buildings.
