The new version of the standard for fire doors introduces the concepts and requirements of some insulated fire doors and non-insulated fire doors from foreign standards. The classification of fire doors is changed from the original classification of insulated fire doors to all insulated fire doors (Class A), partially insulated fire doors (Class B) and non-insulated fire doors (Class C). At the same time, the fire resistance of the original Class A, B and C fire doors is adjusted to 1.5h, 1.0h and 0.5h, which enriches the types of fire door products in our country and increases the choice of practical application. For applications that only require partial insulation or fire integrity of fire doors, partial insulation or non-insulation fire doors can be selected. The new standard also stipulates that if the door leaf is filled with materials, fire insulation materials suitable for the human body should be used to reduce the impact on human health. These regulations not only make the setting of fire doors more reasonable, but also reduce the production cost and raw material consumption of fire doors. Conform to the requirements of building a conservation-oriented society. At the same time, the new version of the standard also increases the content and requirements of steel wood fire doors and other material fire doors, which provides a technical basis for the production and inspection of new materials, new technology applications and new fire doors, and expands the development space of fire door manufacturers.

Fire door manufacturers tell you which parts of the fire door are generally located, as follows:

(1) Close the evacuation stairs to the walkway; close the elevator room to the front room and the door of the front room to the walkway.

(2) Inspection doors for vertical pipeline wells such as cable wells, pipeline wells, exhaust flue and garbage ducts.

(3) Divide fire zones and control the fire walls and doors on the fire partition walls set up in the building area of the zones. When it is difficult to set up a firewall or fire door in a building, it should be replaced by a fire shutter, and at the same time, it should be protected by a water curtain.

(4) specifications (such as the GB50045-95 "high-rise civil building design fire protection code") or design special requirements of fire, smoke partition door.
