The RF-shielding is Frankonia’s basic system and follows the principles of the Faraday cage. The modular and prefabricated high-quality RF-shielding is typically a pan-type shielding made of 2.0 mm galvanized steel that is manufactured to perfection. Frankonia’s shielding is used for all kinds of shielded rooms, such as MRI, Data Center, EMC Anechoic Chambers, or any other room that requires a shielded standard.

Standardization matters to ensure the highest shielding quality and to ensure a maximum of functionality and flexibility that adapts to all special conditions. The complete shielding system is designed to match current or even future modifications and requirements in length, width and height. Thanks to the modular and prefabricated system, modifications can be realized in a very short time at lowest costs, minimizing dirt, dust and noise. Frankonia’s contribution to an overall modular system allows for a complete transfer of all kinds of chamber and is therefore a future-proofed solution.

Each pan-type shielding module offers an all-side reverse bending in order to achieve a self-supporting static structure, and to bolt the modules correctly. Besides this, it allows for an internal installation of accessories without penetrating the shielding. Frankonia’s shielding is prepared for internal bolting that allows an installation very close to the building surface. In special cases, the shielding can be bolted in reverse from outside. The corners are welded completely in-house and so are assured a perfect connection to the surrounding modules. Frankonia’s shielding is a complete self-supporting construction system with a module standard of 3.0 x 1.2 m. In between all modules a highly conductive mesh gasket is integrated that ensures a long-lasting shielding quality. Within this system, all Frankonia components, e.g., honeycombs, doors, feed-through’s or filters offer the same RF quality level.

The standard shielding is made of German steel that offers a minimum of 20.0 μm galvanic coating in accordance with DIN 17162/EN 10142 with quality index DX 52 D+Z. The acceptable tolerance is in accordance with DIN/EN 10143 limited and is a minimum 275 g/m2.

Steel Structure

For static purposes, larger rooms or specific room application (e.g., ceiling supply units) require an additional steel structure support that perfectly meets the shielding fixation, considers a variable static design for different chamber sizes and configurations, and adapts to any specific building characteristics and conditioning layouts. Frankonia’s steel structure is a totally self-supporting system and does not require a connection to the existing building. Furthermore, the steel structure is painted for corrosion prevention. Moreover, Frankonia’s steel structure considers country-specific seismic conditions as well as low point loading to the buildings’ concrete slab.
