The "sliding type" comes in two varieties: manual and electric. Traditional shield doors are often heavy and cumbersome, resembling iron doors, and we have heard opinions that they are heavy and difficult to use. However, our shield doors use shield panels for the door material, significantly reducing the weight of the door itself. They are characterized by very smooth opening and closing operations. As for the shield materials used in the doors, there are three types: "shield gasket," "shield finger," and "magnet." We will make suggestions based on your needs and performance requirements.

It is an anechoic chamber with a panel assembly method using a frame structure, similar to a shield room. The radio wave absorber uses self-extinguishing radio wave absorbers, and by combining them with non-combustible panels, it can be used as a highly fire-resistant anechoic chamber.

This is a shield room with a panel assembly method using a frame structure. The non-combustible shield panel is a non-combustible panel with galvanized steel plates attached to both sides of a magnesium silicate core material. This panel is of the same type used in clean rooms and similar environments. There have been cases where the use of non-combustible panels has allowed for the avoidance of installation requirements for smoke exhaust systems and other equipment. Because it is composed of non-combustible materials, it has a very high ability to stop the spread of fire in the event of an emergency.
