As a tool for daily residents to go upstairs and downstairs, the safety performance of elevators is of utmost importance. Therefore, the prevention of fires in elevators is an indispensable part of daily work. However, there are many real-world reasons for considering cost savings. There is no choice to install fire rated doors. In general, since the elevators are all exposed at the top of the building and exposed to the open air environment, careful consideration should be given to the material selection of the doors. Most customers will use stainless steel fire rated doors because of the frame and the panel material is steel. Materials, after rust treatment, high temperature surface spray, better than general doors. At the same time, the stainless steel fire rated door also has a certain anti-theft performance, forming a certain guarantee for the safety of elevator equipment.

In the event of a fire in an elevator, the surface of the elevator hall door is exposed to temperatures above 1000°C. At high temperatures, the following conditions occur in ordinary elevator hall doors: First,  severe deformation occurs, creating a large gap between the two doors. In the course of escape, people can easily fall into the well and cause casualties. Second, the hall door collapsed or the door panel could not withstand the prescribed force, which caused the personnel to open the hall door accidentally in the escape and fell into the hoistway causing casualties. Third,  severe deformation and loss of closure, causing the fire on the affected floor to spread from the elevator hall door through the hoistway to other floors. Class A fire entrance door fire endurance limit time can reach 1.5 hours, Class B fire rated door fire time is 1 hour, the fire field, the time is the life, this product can restore the loss for us, so the fire door must be valued.
