Update Time: 2019-6-28 16:00:50

When purchasing stainless steel fire doors, users often pay more attention to the situation of the fire door itself and ignore some accessories, but the professionally supplied stainless steel fire door manufacturers said that in fact, it is very important to have three major accessories when installing and using Zhenjiang fire doors . . Stainless steel fire doors can improve the grade of the office or home, and can also protect privacy. The important thing is that the products of stainless steel fire door manufacturers can protect our lives and property, so many people will choose reasonable price stainless steel fire door manufacturers to install it in their offices or homes.
The function of the fire door sequencer is to prevent gaps from appearing in the wrong order during installation, which affects the fire prevention effect. The fire door products of stainless steel fire door manufacturers have relatively high requirements for the heat insulation performance of the products. For example, they can meet the heat insulation effect standard to a certain extent within a specified time. There are corresponding detection methods, and according to the heat insulation effect, Fire doors will also be divided into different grades. The future sales market of insulated fire doors will be larger and more popular, because this is a big demand in the market, and products with fire and heat insulation functions will be better.


In addition to the pipe closer, other fire doors of stainless steel fire door manufacturers should install this accessory, so as to ensure that the door can be closed in time after opening the door. Stainless steel fire door manufacturers also have high requirements for products. There is a fundamental difference between anti-theft doors and fire doors. The big feature of anti-theft doors is that the safety opening function is good, but they cannot be fire and thermal insulation. For us, there is no great fire protection value. In some aisles and shopping malls, no security door is needed, but fire doors are very needed. The security door is not filled with any fireproof material, and their technical standards are completely different.
The main function of the fire lock is to achieve the effect of isolating fire and smoke in an emergency. There are three options available at present, namely fire lock, aisle door lock and handle. You can choose one of them. Good hinges can ensure the normal use of fire doors, so stainless steel fire door manufacturers believe that it is also one of the accessories we must focus on when buying fire doors. Stainless steel fire door manufacturers must go through corresponding tests when the products are shipped from the factory. They must meet national fire protection standards. There is a distinction between Grade A and Grade B products.
