Fireproof treatment of prefabricated steel warehouse

Steel structure company’s steel structure fireproof coating has an early production time, mature technology and excellent fireproof performance. It is often used in frame beams, roof structures, support systems and columns of large steel structure buildings such as airports, railway stations, and prefabricated steel warehouses. fire prevention, etc. In recent years, fires in prefabricated steel warehouses have emerged in an endless stream. There are many factors that cause fires, such as human factors, accidental factors, etc. Today we will talk about how steel structure companies do a good job in fireproof treatment of prefabricated steel warehouse.

1. Heat resistance limit of prefabricated steel warehouse

It is well known that although the steel structure is non-combustible, it is easy to conduct heat. When its temperature reaches above 540 °C, its load-bearing performance drops rapidly, and when the temperature reaches 600 °C, the strength of the steel structure material is almost zero. The fire resistance limit of bare steel is usually only 15-30 minutes. According to the requirements of my country’s steel structure building fire protection design code, the fire resistance limit of steel structure columns, roof load-bearing components, beams and floor slabs is required to be 0.5-3.0 hours. Therefore, it is very important to apply refractory dyes to the fire protection of steel structures. To this end, the steel structure company attaches great importance to the application of refractory dyes, and has a set of strict construction procedures and regular inspection plans.

2. Fireproof treatment of prefabricated steel warehouse

The steel structure company has a special painting and processing department in the factory, from the production of fireproof paint to the painting of steel structure, which is an essential process before the steel structure accessories leave the factory. The support system, etc. are sprayed. After the spraying process, the workers will use a 0.5kg hammer to check the empty drum. If the empty drum is found, the worker will remove the worker will remove the fireproof dye and re-paint the process until the next process cannot be entered until the fireproof treatment of prefabricated steel warehouse has no errors.

3. Regular inspection and maintenance

In addition, in order to better ensure the safe use of prefabricated steel warehouses, steel structure companies need to conduct house safety inspections on prefabricated steel warehouses every 4-5 years during the daily maintenance process, and require the warehouses to provide compliant house safety Test report. The type of warehouse structure, the number of floors, the address of the house, the age of construction, the current cracks, damage, coating peeling, steel corrosion, joint damage, welding appearance defects, connection and fastening conditions, etc. The scope of regular inspection by steel structure companies.
