Shandong Xinming FRP Products Co., Ltd.

The new lightweight composite protective equipment (civil air defense doors, lightweight civil air defense doors, civil air defense airtight doors, protective airtight doors) jointly developed by Shandong Xinming FRP Products Co., Ltd. and the Fourth Design and Research Institute of the General Staff has filled the current gap in domestic civil air defense equipment. Yes, it is a national patent product. , light weight and high strength
The material of the civil air defense door leaf is low-pressure molded fiber reinforced sheet mold composite material, which is light weight and high strength. Compared with the civil air defense door of the same specification, the light civil air defense door leaf is lighter in weight by more than %. The anti-explosion test proves that the strength of the light civil defense door fully meets the standard.
, Corrosion-resistant, long life
The civil air defense door is made of polymer thermosetting fiber reinforced sheet mold composite material, which has certain resistance to acid, alkali and other chemicals. The light civil air defense door can be used in the basement all year round. It will not rust or rot in a humid environment and has a service life of more than 10 years.
Therefore, lightweight civil defense doors are an excellent alternative to traditional inventions.
, easy to install, maintenance-free
The light civil air defense door lock adopts a four-link driven slide bolt lock, which is light in weight, simple in structure and easy to operate. Compared with traditional reinforced concrete and steel structure protective equipment, it is lighter in weight and easier to install. In addition, the surface of the door leaf adopts a low-temperature baking process, which eliminates the need for maintenance in the future.
, Other advantages
Civil air defense doors also have many advantages such as high productivity, good insulation, sound insulation, flame retardancy, moisture resistance and beautiful appearance.
