According to daily life, disasters often bring incalculable loss of life and property to human beings. As far as fire is concerned, it not only caused major losses in terms of property, but also caused people's casualties.

Buildings in Taiwan (such as garages, factories, or homes in buildings) are mostly in their fire isolation areas (especially the isolation areas used to isolate and control fire sources to prevent the fire from spreading outward). There are iron roll doors around or at the entrance and exit. In the event of a fire accident, in order to effectively control the spread of the fire, prevent it from spreading outside the fire isolation area, and obtain more escape time for the trapped people, it is usually required that the iron roll door must be able to provide sufficient fire and heat resistance ability.

Generally, the structure and components of traditional fire-resistant rolling doors are bladed and formed from a single steel sheet, so when one side is heated, the heat will be directly transmitted to the other side without any heat resistance effect; or double-layer resistance The hot blade is made of double-layer steel sheet, and the interlayer is filled with heat-resistant layer materials such as foamed polyurethane or heat-resistant glass fiber cotton. However, because the upper and lower blades are hooked to each other, There is no heat resistance design, so the heat will still be directly conducted from the hook to the non-fire surface; it can be seen that the above two conventional blades can not meet the requirements of heat resistance performance.
