Fire doors are doors made of fire-resistant and flame-retardant materials that have fire resistance stability, integrity, and thermal insulation properties. They are mainly used for firewall openings in building fire compartments, stairwell entrances and exits, evacuation corridors, pipeline entrances, etc. They are commonly used for personnel passage and can prevent the spread of flames and the flow of combustion smoke in the event of a fire. They also play a sealing role when the positive air supply system is working. In today's increasingly mature fire protection technology, buildings with fire protection requirements all have the presence of fire doors. Currently, the vast majority of fire protection design specifications in China explicitly require the use of fire doors.

At present, there are more than a thousand enterprises in China that produce and sell fire doors. There are many types of fire doors sold on the market, but there are only a few products with truly excellent quality. The prices of various fire door products vary greatly, with some even differing by several times. Counterfeit and shoddy products that pass off inferior goods as good are still ubiquitous in the market.

Many manufacturers produce fireproof door steel plates with a thickness only half of the standard, and the filling materials have poor fire resistance, insufficient thickness, and poor fireproof board quality. Some companies even spend a high price to purchase samples for testing in order to obtain market access certificates for related products. After obtaining the certificates, the quality of their own products still does not meet the standards.

The relevant person in charge of the Fire Department of the Ministry of Public Security once told the media that in recent years, the construction of public fire protection facilities and the demand for fire safety products in China have increased sharply, and the fire protection industry has shown unprecedented development momentum. Currently, the entire industry has more than 10000 production and service-oriented enterprises, producing nearly a thousand varieties of fire protection products. However, the market order of fire protection products in our country is still relatively chaotic, with a large number of inferior fire protection products flowing into construction projects and fire protection systems, resulting in ineffective fire protection facilities and causing a large number of fire hazards, seriously endangering public safety.

The new standard has been revised in terms of the types, classifications, production materials, related concepts and requirements of fire doors, and has stricter requirements for product quality identification and inspection, which is a thorough reshuffle of fire door enterprises. Whether they can successfully pass the new standard appraisal and obtain a new certificate has become a huge challenge for fire door production enterprises. Having this new ticket is the primary prerequisite for all enterprises to continue selling.

Experts say that fire doors play a crucial role in fire isolation equipment in various buildings. The effectiveness of fire doors during a fire is closely related to the magnitude of the damage caused by the fire. According to authoritative data analysis, 82% of the deaths in fires in densely populated areas are caused by inhaling toxic smoke released from the combustion of indoor decorative materials, resulting in poisoning and suffocation. The deadly culprit in fire accidents is often not fire, but smoke. Because many people had already fallen into unconsciousness and died in the fire due to inhaling excessive toxic smoke before the fire spread significantly. (From Huicong Fire Information)
