What are the dimensions and specifications of fire doors?

In fact, fire doors, like security doors, play a preventive role. Security doors will be installed in almost every household and installed at the main entrance of the house, while fire doors will not be installed in every household, but at least every floor of every building will be installed at the entrance and exit of stairs. Mainly plays the role of isolating flame and fire. The acquisition of fire doors is very strict. Accredited laboratories must be designated by the Economic Affairs Department of the Fire Department. According to the new national standard GB _ 1 2955-2008, which was implemented on June 65438+1October12009, the fire door has passed the fire resistance test, and the Bureau of Standards and Inspection of the Ministry of Economic Affairs has issued the verification login certificate and authorization mark. It can be seen that fire doors have some national standards. Let's get to know the size specifications of fire doors.

Specification for dimensions of fire doors-Dimensions of common fire doors

Fire doors include wood fire doors, steel fire doors, stainless steel fire doors, fire glass doors, fire entry doors, steel fire doors, etc. The functions of the products are similar, and they all play the role of fire prevention and isolation. Consumers choose different materials according to different places and functions, and the size of various fire doors is also limited by the differences in the performance of manufacturing materials.

The relatively fixed specifications are fire-proof entrance doors and steel-wood fire doors. These two products are mainly used for home doors and office doors. So generally speaking, the sizes are relatively fixed, mostly single-mouth and sub-female, mainly 950mm*2050mm and 1 150mm*2050mm, which are relatively unified in manufacturing and installation.

Ordinary wooden fire doors, stainless steel fire doors and fire glass doors are mostly customized in size. At present, the domestic requirements are that the maximum width is 2 100mm and the height is not more than 2300mm, and it must be determined according to the fire door inspection report obtained by the fire door manufacturer. Some enterprises may get less qualifications, such as 1800*2 100, 1500.

The conventional size of steel fire doors is also less than 2 123. For the parts of super-large fire doors, the fire door factory approved by the state that meets the manufacturing conditions can produce super-large steel fire doors. At present, our company can provide 3000mm*3000mm, 2700 mm, 2500 mm, 2400mm and so on. To meet the needs of large industrial doors. Need to be reminded that at present, there are very few enterprises that can manufacture super doors in China, and users must buy them from qualified super-large fire door manufacturers.

Specification for dimensions of fire doors-Dimensions of oversized fire doors

Compared with the related documents of 20 14, the height and width of oversized fire doors are not more than 2300mm and 2 100mm respectively. Products exceeding this specification are called oversized fire doors.

With the demand of the market, the demand of users; Relevant departments allow fire door manufacturers capable of producing super-large specifications to apply for approval and obtain corresponding qualifications; However, at present, the vast majority of the market is only for the declaration of individual items and individual sizes; Instead of the qualification of ordinary fire doors, you can produce them at will after you get them.

At present, there are two kinds of manufacturers who claim to be able to manufacture oversized fire doors. One is an unlicensed enterprise. The enterprise's practice is to apply for manufacturing approval for the project and door size as much as possible after receiving satisfactory orders; This situation applies to enterprises that have already obtained a certain project qualification, and the other is enterprises that have already declared and obtained relevant qualifications. We mainly talk about the latter situation.

According to the understanding of obtaining the production qualification report of fire doors before, since such enterprises have obtained the super-door report, they can process and produce within their maximum size range; In fact, the difference is here; The production qualification of ordinary steel fire doors is covered, for example, it has obtained the qualification of 2 123, which means that the fire doors of this manufacturer can be produced to a maximum width of 2. 1 m and a height of 2.3 m; Anything within its range can be generated, such as 182 1, 1523, 1220, 14 19, etc. , as long as it is double-open; However, the super gate is not. If you get 3000 * 3000 production qualification, you can only produce doors with a width of 3 meters and a height of 3 meters. If you need to produce other sizes, you must have a corresponding report; This explains why some companies' reports on a project are useless in different sizes.

The above is the description of the dimensions and specifications of fire doors, and I hope it will be helpful to everyone. Although we feel that there are many similarities between security doors and fire doors, the main function of security doors is to have better prying and sealing performance. Generally, you can't open the door without a key outside the back door, and the filler in the door panel is not fireproof material. Fire doors must be opened 24 hours a day and cannot be locked without permission, because locking is not allowed, which has great security risks. Therefore, we must treat fire doors and security doors differently.
