[0002] At present, steel fire doors are widely used in construction. Compared with stainless steel fire doors and wooden fire doors, the surface of steel fire doors can be more colorful. By simply electroplating or painting the surface of the steel fire door, you can get the various very beautiful appearances that the designer wants. At the same time, through measures such as frame grouting and built-in insulation materials in the door leaf, it can meet the requirements of various fire protection grades. However, in buildings with extremely high requirements for details and overall decorative effects, such as museums, art galleries, exhibition halls and other buildings with large spaces and high degree of integration, although the appearance of the surface can be infinitely close to the decorative wall, due to the exposed frames and hinges of traditional steel fire doors, as well as the difficulty in closing the decorative wall, especially the light steel keel wall, it is impossible to integrate with the decorative wall, which looks very abrupt and seriously affects the overall beauty and decorative effect.
