Frankonia Shielding & Steel Structure

Frankonia shielded rooms and anechoic chambers are designed based on a modular construction system. Prefabricated high-quality PAN type shielding modules guarantee a maximum of flexibility and usability paired with a vast shielding attenuation throughout the complete shielding system.
The standard modules are bolted from inside every 75 mm with high conductivity mesh gasket inserted for sealing the joints of the panels. This facilitates an installation close to the walls of the parent building.

Frankonia‘s steel construction is totally self-supporting and does not require any connection to the existing building. Frankonia’s steel structure is made of strong steel beams which are designed and manufactured in-house. It considers a variable static design for different chamber sizes and configurations and adapts to any specific building characteristics. The design is made in order to attain best stability and lowest point loads for the concrete slab of the building.

Features

PAN type shielding panels made of 2,0 mm galvanized sheet steel, min. 20 µm acc. to DIN 17162 – EN 10142-Quality DX 52 D + Z, thickness of the galvanization 275 g/m²

Self-supporting stability

Static steel structure for any country-specific seismic condition

Mounted from the inside, optional interior finishing, insulation or lead lining on request

Reverse installation possible (flat surface inside, e.g., reverb characteristics, or local absorber lining)

Raised floor systems, or welded floor systems

Everything remains modular with screwing standard

Nothing is glued or welded, no timber works

Long-life shielding attenuation characteristics for the complete shielding system and products

Dismountable without any damage, easy modifications and maintenance

A complete transfer or future modification is possible

Painting of the steel structure for corrosion prevention

Frankonia Door & Gate Solutions

Frankonia’s doors and gates are constructed and manufactured acc. to state-of-the art technology and are compliant with valid EMC standards. The triple-row knife-edge system achieves the same shielding effectiveness as the standard shielding modules by its innovative design, and therefore offers continuous quality. Thus, the maintenance intervals are reduced to a minimum, ensuring a stable shielding performance.
