Characteristics and applications of fireproof sandwich panels

Fireproof sandwich panel is a composite panel composed of two layers of metal panels filled with fireproof insulation material in the middle. Its outer metal panel has good corrosion resistance and impact resistance, while the fireproof insulation material filled in the middle can effectively block the spread of fire and improve the fireproof performance of the building. In heavy steel warehouses, fireproof sandwich panels are mainly used to cover exterior walls, roofs and other parts. They can not only meet the thermal insulation needs of the warehouse, but also significantly improve the fire safety level of the warehouse.

The role of purlins in heavy steel warehouse structures

Purlins are key components in heavy steel warehouse structures and are mainly responsible for supporting roof panels and distributing loads. In fireproof sandwich panel heavy steel warehouse with the purlins, the purlins are usually made of high-quality steel and have sufficient strength and stiffness to ensure the stability and safety of the warehouse structure. At the same time, the purlins and fireproof sandwich panels are closely combined to form an overall stress-bearing system, which effectively improves the overall wind and earthquake resistance of the warehouse.

Key elements of structural safety of Chongqing Steel Warehouse

Steel quality and selection

Steel is the main structural material of heavy steel warehouses, and its quality and selection are directly related to the structural safety of the warehouse. When selecting steel, full consideration should be given to its yield strength, tensile strength, elongation and other performance indicators to ensure that the selected steel meets the design requirements. At the same time, the cross-sectional size and model of steel should be reasonably selected based on the use function and load conditions of the warehouse to ensure the stability and load-bearing capacity of the structure.

Fire protection design and measures

Although the application of fire-resistant sandwich panels has improved the fire-proof performance of the warehouse, further fire-proof measures still need to be taken. First of all, it should be ensured that the fire protection grade of the fire-resistant sandwich panel meets the design requirements and is installed in strict accordance with the specifications during the construction process. Secondly, complete fire-fighting facilities should be installed inside the warehouse, such as fire extinguishers, fire hydrants, etc., so that they can be put out in time when a fire occurs. In addition, fire safety inspections and drills should be conducted regularly to improve employees’ fire safety awareness and emergency response capabilities.

Anti-corrosion and maintenance

During the use of heavy steel warehouses, they will be affected by various factors such as the natural environment and climatic conditions, and are prone to corrosion and damage. Therefore, anti-corrosion and maintenance work are crucial to ensure the structural safety of the warehouse. During the design stage, the anti-corrosion properties of steel should be fully considered and coatings with excellent anti-corrosion properties should be used for coating. During use, the warehouse should be inspected and maintained regularly to detect and deal with problems such as corrosion and cracking in a timely manner to ensure the integrity and stability of the structure.


The fireproof sandwich panel heavy steel warehouse with the purlins plays an important role in the field of warehousing due to its excellent performance and wide application prospects. By in-depth analysis of its structural characteristics and key elements, we can better understand its principles and methods for improving structural safety. In the future, with the continuous advancement of science and technology and the continuous emergence of new materials, the structural safety of FAMOUS Steel Engineering's heavy steel warehouses will be further improved, providing a strong guarantee for the sustainable development of my country's logistics and warehousing industry.
