Beschreibung
Zusammenfassung:	The invention provides an armor-piercing-resistant protective door which is composed of a protective door grid-type fixed framework, a lead plate protective layer and a depleted uranium square spindle. The protective door adopts thick grids shaped like the Chinese character 'jing'. The depleted uranium square spindle is filled in the grids. The lead plate protective layer is adopted as a protective layer of two sides of the grids, and then stainless steel plates are glued on the surfaces of the grids for decoration and anticorrosion. Because high-intensity metal materials are used, a kinetic energy armor-piercing bomb can not puncture the door, and the door can be used in airplane air-raid shelters, traffic tunnels and other occasions with high requirements for protection grades.
