Steel single opening insulated fire door

Doors are present in each of our homes. And we are very familiar with it. Not only that, we can say that it is closely related to the steel single-opening insulated fire door. for the door. Do we understand it? What is its structure? As for doors, we know that most homes have security doors installed. But today we tell you that although theft prevention is very important, we must also pay attention to fire prevention.
So do we know about fire doors? Now let Tongxiao introduce it to you! After more than ten years of development in my country's fire door industry, product quality and performance have been greatly improved, and product types have also increased. The original standards are no longer applicable to guide the production, quality supervision and inspection of this product. According to the plan issued by the National Standards Committee, the "General Technical Conditions for Steel Fire Doors" and the "General Technical Conditions for Wooden Fire Doors" will be integrated and revised to unify the technical requirements for various fire doors. During the revision process, the Tianjin Fire Protection Research Institute of the Ministry of Public Security referred to international standards and standards of foreign developed countries, and conducted in-depth investigation, analysis and research based on the production, installation and use of fire doors in my country. The new version of the standard introduces some concepts and requirements for insulated fire doors and non-insulated fire doors from international and foreign standards. The classification of fire doors has been changed from the original classification of only insulated fire doors to insulated fire doors
(categories), partially insulated fire doors (categories) and non-insulated fire doors (categories). At the same time, the fire resistance limits of the original Class A, B, and C fire doors have been adjusted to enrich the fire door products in my country. Types increase the choice of practical applications. For applications that only require partial insulation or fire-resistant integrity requirements for fire doors, partially insulated or non-insulated fire doors can be selected. The new version of the standard also stipulates that if the door leaf is filled with materials, fireproof and heat-insulating materials that are non-toxic and harmless to the human body should be used to reduce the impact on human health. These regulations not only make the installation of fire doors more reasonable, but also reduce the production cost and raw material consumption of fire doors, in line with the requirements of environmental protection and building a conservation-oriented society. At the same time, the new version of the standard also adds the content and requirements for steel, wooden fire doors and fire doors made of other materials, providing a technical basis for the application of new materials, new technologies and the production and inspection of new fire doors, and expanding the scope of steel single-opening thermal insulation fire doors. Development space for door manufacturing enterprises.
